Not all industries have the luxury of lush margins. It is therefore even more important to work with an experienced partner to design processes that are efficient and energy-saving and ensure the availability of the plant. Do you have your energy costs under control? Energy consumption is becoming increasingly important, and not only for reasons of sustainability. For products with low margins, every cost saving is significant. In many bulk material processes, transport within the plant is an energy guzzler. Tons of material often have to be moved. Here it is important to select the right conveying technology with the expertise of the plant designer, which also takes into account the properties of the bulk material. In a highly standardised production, switching from batch production to a continuous mixing process can also save a lot of energy. Plant failures due to abrasion? Many bulk solids, such as pigments, are very abrasive. Abrasion plays a role wherever bulk solids move. The correct design of the piping, the type of conveying and the right choice of equipment have a dramatic effect on the service life of the plant components. GB Elbows from Gericke are an effective method…

Gericke has delivered multiple dense phase pneumatic transport systems for the gentle and safe transport of fine toxic NMC powders used for the battery production.

Saving energy is a key pillar of a sustainable production environment. With the introduction of highly efficient IoT drives for its GMS batch mixers, Gericke supports their customers in achieving their ambitious goals. GMS mixers The proven GMS mixers are now combined with a highly energy-saving workhorse: a new, very efficient drive, based on a permanent magnet motor. In these motors, the magnetic field is on one side created by a permanent magnet, which offers several key advantages. Strong and efficient The delivered torque is constant over the entire speed range, which makes these motors ideal for batch mixers that start and stop frequently. Since the magnetic field only needs to be built up on one side, the efficiency of the motors is significantly higher than that of asynchronous motors. The international energy rating for such a motor is “ultra premium efficiency” (IE5). In addition to the higher rating, the high torque that can be delivered also indirectly reduces energy consumption, as the motor does not have to be oversized for the start-up. Compact and quiet Space limitations are often seen in a production plant, especially when an existing installation needs…

Twin vessel dense phase conveying is the solution when minimal height is available and when at the same time the product needs to be conveyed gently without any creation of fines. A customer had major issues with a belt conveyor that should transport the instant chocolate drink powder from production to a sieve placed right above the filling lines. The installed belt conveyor contaminated the powder with wear which was not acceptable. Because all upstream equipment was already installed, less than 1 m below a discharge rotary valve was available. A lean phase pneumatic conveying system with negative or positive pressure would have been possible. However, because the powder must be treated very gently minimising the creation of fines during the transport, a low velocity dense phase conveying system Gericke PulseFlow PTA with two vessels was selected. The two 20 l pressure vessels were placed side by side and successfully fitted below the continuously discharging rotary valve. The chocolate powder is fed at a rate of 1.5 t/h into one pressure vessel while the other vessel is conveying and alternating. This mode generates a continuous product…

The accurate dosing of powders, flakes or granules is a widespread operation in all types of process industries, and for various process applications such as feeding of mixers and reactors or filling of bags. The right selection ensures recipe consistency, automated production and prevents product rejects. Gericke manufactures a broad range of feeders for use in applications in the raw materials, chemical, food and pharmaceutical industries. To find the most suitable feeder, a number of points have to be considered. A precise dosing operation requires a high performance feeding unit, adapted to the rheology of each of the products to be dosed, capable of a very wide range of feed rates in order to deliver a high rate of flow to limit the duration of the operation but also a very low flow rate to adjust the flow to the required precision. Often a weighing system is part of the dosing unit, depending on the size of the batches and the desired accuracy. Such gravimetric systems can work as “loss-in-weight” or “gain-in weight” feeders. Loss-in-weight is if used to provide a controlled flow of material (kg/h), gain-in-weight is most often used to provide a batch…

Rotary valves operate under various conditions. They feed, convey or isolate powders of the most different characteristics. In the construction chemical, environmental or mineral industry they handle specific abrasive products like glass cullet, carbon, cement, dolomite, quartz and more. They are exposed to important effects of abrasion. The wear of the rotor but also of the body happens even if the rotary valves are made of hardened materials and alloys. Such treatment will prolongate the working life but will not avoid the abrasion completely. The conclusion is that sooner or later, the rotary valve has to be undertaken a revision and worn out parts have to be replaced. Otherwise the leakage will increase, and the operation and duty of the valve cannot be fulfilled anymore. The OEE (overall equipment effectiveness) will decrease. Gericke has developed its EHDM rotary valve for these applications. The goal is to increase the lifetime, shorten the downtime and make…

From humble beginnings in the year 1894, the company Gericke evolved into a globally positioned and successful provider full of solutions in the bulk goods industry. This is reason enough to take a look at the Swiss family business‘ history. 1894 in the heart of Zürich Ing. Walter H. Gericke founded his machine and mill building factory. He attained quickly an excellent reputation as a specialist and as a reliable supplier of modern, partly already automated, milling plants. He sold roller mills from the prestigious company Seck from Dresden. Other important process steps involved particularly corn cleaning, storageing, conveying, sifting and mixing grains and flours. The vast array of machines was already widely-ranged. At the beginning of the 20th century Gericke constructed its first vertical mixers and celebrated a major success with the patented „Soder-mills“, which resulted a higher yield. Innovation was in the foreground in the 40’s with the construction…

Evolution not revolution August 2018 sees the initial launch of the new Gericke GS centrifugal sifter. The new range of GS centrifugal sifters is the evolution of a long established design principle, highlighting Gericke as an industry leading sifter manufacturer. On commencing his position as General Manager at Gericke UK, Colin Arlott assessed the information and feedback from existing centrifugal sifter installations and decided that a new machine with an evolved design was required to meet today’s productivity demands, a machine with sound engineered solutions fit to bear the Gericke logo. The project began in earnest in January 2018 with the analysis of sifting machines in operation around the world, identifying the various design features which have proven successful with operators and maintenance engineers alike, and importantly, identifying features which had not performed as expected within process environments. This analysis provided a focus for evaluation and a direction to…

For small headroom The advantages of pneumatic dense phase conveying systems are well known. Minimum air consumption, high product loading and throughput, little wear on the piping and preserving the product quality. Pressure vessels require in general a certain height to be installed, which is not always available. As an alternative, rotary valves are used, with all negative side effects as air leckage, wear and product attrition. Gericke has developed a small conveying pressure vessel, which, with its 20 liter volume, requires only the headroom of 660 mm! The smallest sender Gericke PTA/PHF 20 performs although with a throughput of 1.5 m3/h and up to 50 meters. It is equipped with a level probe and the additional air volume control makes the conveying even more efficient. The dense phase conveying can be carried out either as product-gentle plug conveying or thrust conveying. The Gericke STP 61 machine controller ensures trouble-free and fast commissioning and maximum conveying…

The conveying gas (air, nitrogen) enters the vessel and conveying pipe in pulses. Depending upon the product, separate or wave plugs are formed, which are moved slowly by the conveying air in the pipe to…

2 Tasks, 1 Machine Increasing cost pressure especially in the production of consumer goods, in combination with higher complexity of recipes and production result in new requirements to processes and machines. By integrating two normally separated production steps into one machine investments can be reduced as well as space requirements.

The general trend towards shorter product life cycles and towards individual customer manufacture in small batch sizes affects the whole manufacturing chain. As a result, operators of production plants require their operating organisation and machine equipment to be designed and implemented to cope with frequent product changes and small production batches with consistent quality at defined costs. This means for the bulk material processing industry to keep manufacturing batches separated when products are changed. A contamination between the different batches is inconvenient in the best case. In the worst case, however, this can result in the total loss of the produced batch. Along with the costs of the raw material used, increased costs may arise for the disposal of the contaminated material. The resulting loss of profits must also not be forgotten if the faulty batch is not accepted and cannot be processed further. The clean separation of batches when processing…

Dating back to the summer of 1894 is when the family run company Gericke was first set up. At that time, flour milling was among the first industries to incorporate automatic handling systems for bulk solids. Operations such as cleaning, conveying, storing, discharging, feeding, grinding, mixing, separating, de-dusting and bagging were already being developed. With the emerging influence of the third Gericke family, the company established a strong development of philosophy for expansion and growth. Now over 120 years on the company is still going strong under the 4th generation management of Mr Markus Gericke. Gericke started with just one location in the industrial district of Zurich and has now expanded world-wide by establishing subsidiaries in key countries which currently employs over 260 committed employees. People are the company’s greatest asset and hold a key position in all future development plans. With the delegation of responsibility and…

and actively used for the environment and for consumption Activated carbon is used in industrial and commercial cleaning processes due to its characteristic properties. It is used to remove and filter out unwanted substances from liquid and gaseous mix- tures. A precise feeding of the activated carbon is indispensable - both to properly control the cleaning process and to use the expensive raw material activated carbon (well over 1,500 € / t) in a cost-efficient manner. Activated carbon in waste water treatment With the increasing demands from environmental legislation, operators of waste water treatment plants need to add additional cleaning steps to the established waste water treatment process. They must ensure that substances which previously passed through the cleaning process are removed as fully as possible from the waste water. The use of activated carbon allows such toxic materials or those which have poor biodegradability, to be removed from the waste water. To do this, activated carbon is added to the…

Gericke differential feeder with vibration tubes Sensitive bulk materials are a major challenge to a metering feeder in two ways. Products such as flakes, cereals and sensitive chemicals must not only be precisely fed but they are also extremely sensitive to pressure and shearing forces. Gericke offers the differential feeding technology combined with vibratory feeders for applications of this type. Gericke combines the best of two worlds with the DIW-V differential feeder with vibration tubes. The Gericke differential technology compensates for the tare weight of the scale holder so the load cells of the scale can use the complete measurement resolution for the feed product. The vibration tube from the discharge unit reduces the forces acting on the feed product. The shearing and pressure forces are greatly reduced compared to a feeding helix. This makes the DIW-V of interest to a very wide range of industries, regardless of whether the feed product is oxide ceramic, chocolate flakes or chips. The advantages…

Gericke customers increased their bulk handling know how How can sources of bacterial contamination and sediments already be reduced to a minimum when planning a system? Which steps ensure fastest possible process from product idea to industrial mixing system? Participants at Gericke’s 2012 customer seminar received compre-hensive answers to questions like these. Just under 120 participants from 59 different compa¬nies took the opportunity to attend the customer semi¬nar held by the bulk material pioneer from Regensdorf in Switzerland. The fact that visitors came from ten different countries shows that it is worth travelling a considerable distance to participate in a seminar of this kind. Hygienic solutions – from simple coffee pots to indus¬trial plants – were presented by the guest speaker, Hans-Werner Bellin. As an expert for hygienic design, he explained the legal basic principles in Europe and using positive and negative examples. He showed how one can protect a product from unnecessary contaminants…

In many cases, the belt weighers presents an interesting alternative to screw feeders as it achieves high feed rates and…

Reduction of energy required when processing bulk materials When taking a look at the aspect „Application of energy during engineering processes“, in connection with systems engineering, this has to be approached from various angles. A change in chemical or physical characteristics, which is a necessary part of value-adding design of products, is often effected by means of a mechanical or thermal action. Energy is added during the process. Application of energy is necessary. When designing a system for the processing of bulk materials, the equipment manufacturer has the possibility to select machines with low energy demand with expert selection of layout and process design without affecting the result adversely. There is plenty of scope of action for the designing of energy-efficient production processes! When handling mixing processes, Gericke often decides on a continuous process design as this means that logistics can be simplified and drive power per kg of processed product is minimised. The GCM line (Gericke Continuous…

Continuous mixing processes for pharmaceutical solids A new kind of micro mixer now makes it possible to carry out continuous solid substance processes in the pharmaceutical industry. This increases flexibility when compared with the traditional batch process and also reduces the space required for this. The Food Drug Administration FDA, the American approval authority for pharmaceutical products, started the initiative “Continuous Manufacturing” some years ago. This initiative is aimed at improving the production process, shortening the time required for the development of a product which in turn then leads to reduced production costs. Gericke have extended their range of GCM continuous mixers to ensure optimum processing of these very small throughput volumes. The GCM 250 is designed for a capacity of 1 - 200 kg/h allowing a tablet compaction unit, for example, to be installed directly upstream for the blending process. The mixer has a cantilevered mixing rotor with a quick release connection. A purely metallic…

Gericke’s Multiflux® mixer GMS creates with its 2 horizontal, overlapping mixing rotors a fluidized bed. As a mixing process is based on the exchange of the particles in a volume by convection, this principle is very efficient for the energy-saving and product respecting mixing. The GMS mixer is known as long-lasting and reliable process equipment. In order to complete its existing range, Gericke has made a redesign of the GMS Multiflux mixer that responds to the increasing demand for hygienic execution in the food and pharmaceutical industry. The new model is called GMS C. C stands for cantilevered and refers to the 2 shafts that are cantilevered, offering many advantages. Not only the number of sealing is divided by 2. Due to the construction, the front side of the mixer can be opened entirely. In the high end version, named the GMS ECD, the operator can pull out the complete drive and mixing shafts out of the body. Large lateral doors offer an easy access…

Highest mixing homogeneity and the hygienic design characterize the continuous mixers GCM made by Gericke. The series has now been further improved by the models type GCM ECB.

The experiences made with the mixers during the operation have been incorporated in the design of this latest model. For the user it means a remarkable improvement in regard of accessibility to all components and excellent cleanability of the mixer. The GCM mixer is suitable for the operation in ATEX zones. Optionally the mixer can be…

Wear resistant cone valve for dense phase pneumatic conveying of abrasive materials The biggest advantages of dense phase pneumatic conveying systems compared to dilute phase systems are that slow conveying speeds, large conveying distances, high solids loadings and thus high capacities are possible. With minimizing the speed for example the effect of wear and attrition can be reduced to a large extent. However, for dense phase systems a higher pressure gradient must be available and therefore it is vital to have a pressure tight conveying system without any leakage. One of the most critical parts when using a pressure vessel for abrasive materials is the inlet valve. The sealing membrane of a butterfly valve for example can be worn out quickly leading to leakage air which can disturb or completely stop the conveying process. Gericke offers now an improved cone valve (type K5 and K6) which is especially suited for applications with abrasive materials, high pressures and high temperatures. The valve shows excellent wear resistance for abrasive bulk…

Great interest in the Powder Handling and Processing Seminar of Gericke The acquisition of systematic knowledge of particle properties and bulk material behaviour is a big topic in the research and practice. We would like to operate on the design of machines and equipment for bulk processes with scientific knowledge rather than empirical estimates. This topic was a focus on the very well-attended Gericke Bulk Seminar in Regensdorf, Switzerland. The numerous attendees from Europe and overseas followed all presentations and test units with great interest. Gericke has presented a device for measuring particle properties made by Freeman Technology.

The advantages of Gericke`s Easydos Pro Controller for gravimetric feeding Manufacturer of continuous feeders do not offer only PLC based control solutions but also specific, dedicated controllers for gravimetric feeding equipment. The idea to use PLC control parts instead of supplier owned technologies may seem easy. From a financial and process point of view it is worth in most cases and more attractive to use the specific feeding controller of the manufacturers and to link them to the parent IT structure by using Ethernet/IP or bus protocol. Gericke offers with EASYDOS Pro a controller that can be used flexibly and reliably in different feeding processes and is linked to its environment with powerful communication interfaces. A feeding ensemble is embedded in upstream and downstream process stages. Their influence and interaction to the feeding equipment and control is considered during the design phase of a feeding installation. Modern control solutions, tailored as EASYDOS Pro for feeding applications are usually better configurable…

Rotary Valve with Contact Detection System Developed to eliminate the problem of “Nuisance Tripping”, Rota Val’s new RotaSafe RM2™ rotor monitor is claimed to represent a reliable and most advanced solution for rotary valve rotor protection. Detection systems are required to stop a rotary valve instantly if it detects rotor to housing contact, avoiding valve damage and consequent product contamination. Even relatively minor internal valve damage almost certainly invalidates ATEX certification requirements by opening a flame path. Significant reduction of this problem can save considerable expense in repair or replacement of affected valves. The Rota Val RotaSafe RM2™ detection circuit is intrinsically safe and therefore suitable for all ATEX Zones. Rota Val’s RotaSafe RM2™ has innovative control electronics, effectively filtering unwanted electrical noise from unavoidable sources that produce false signals. The new system is unique in that it can be adjusted to measure contact resistance at…

Gericke Systems for Powder Handling For more than 115 years (founded 1894), Gericke has been planning and supplying systems for pow-der handling! In the pneumatic conveying technology as well as in the feeding and mixing technology Gericke belongs to the market leaders. At the beginning of every project when designing a feeding and mixing station there is the question whether to create a batch or continuous process. To come to a conclusion, a careful analysis of the products and processes involved is required, considering the further conditions and criteria. Some-times, the advantages might be with a batch solution, but there are other processes where a conti-nuous system might be preferred. Gericke undertakes great efforts in R&D in pneumatic conveying, feeding and mixing technology and offers additionally components for quality control, e.g. equipment for size reductions and sifters. The know-how based, competent treating of a project is what a customer gets when speaking with Gericke. Gericke…

Highest mixing homogeneity and the hygienic design characterize the continuous mixers GCM made by Gericke. The series has now been further improved by the models type GCM ECB.

The experiences made with the mixers during the operation have been incorporated in the design of this latest model. For the user it means a remarkable improvement in regard of accessibility to all components and excellent cleanability of the mixer. The GCM mixer is suitable for the operation in ATEX zones. Optionally the mixer can be…

The volumetric and gravimetric Gericke feeders, with their high feeding accuracy, robust construction and modular design, rank among the highest-quality feeders on the market. In the case of volumetric feeders, feed rate is normally not regulated continuously, but should remain constant if there is no change in bulk density. A precondition for this is constant filling of the metering organ. Feeding of the bulk material, when using the GDU610, is carried out by means of a metering helix or metering screw. Here at Gericke, we attach a great deal of importance to the linear course of the feed rate in connection with the development of a volumetric feeder. The feed rate depends on the volume transported per time unit. Precise volumetric metering is also an important precondition for high gravimetric accuracy. The new all-purpose GDU610 feeder with complete emptying covers a feed rate range from 340 l/h to 36.000 l/h. The feeder can be used in connection with products…

Vibrations occur above all in production plants and can generate many different types of horizontal and vertical oscillations in a large variety of frequency ranges caused by the drives of the integrated machines. The metering result is influenced decisively by the vibration severity measured in the form of acceleration of the vibrations. “How well do the weigh feeders compensate defined intensities of vibration?” Research carried out by the University of Applied Sciences Constance showed that an acceleration of vibration of up to 0.5 m/s² did not affect the metering accuracy of the Gericke hybrid weighing technology. It emerged that, especially mechanical damping plays an important role when improving on metering accuracy. Tests made it clear that the reduction of transference of vibrations to the system (as a whole) was not achievable by using heavy weights nor were rubber feet suitable as vibration dampers for significant reduction of the effects of the vibrations.…

Gericke’s Multiflux® mixer GMS creates with its 2 horizontal, overlapping mixing rotors a fluidized bed. As a mixing process is based on the exchange of the particles in a volume by convection, this principle is very efficient for the energy-saving and product respecting mixing. The GMS mixer is known as long-lasting and reliable process equipment. In order to complete its existing range, Gericke has made a redesign of the GMS Multiflux mixer that responds to the increasing demand for hygienic execution in the food and pharmaceutical industry. The new model is called GMS C. C stands for cantilevered and refers to the 2 shafts that are cantilevered, offering many advantages. Not only the number of sealing is divided by 2. Due to the construction, the front side of the mixer can be opened entirely. In the high end version, named the GMS ECD, the operator can even pull out the complete drive and mixing shafts out of the body. Large lateral doors offer an easy access…

Feeding particularly low feed rates when hygiene is a central issue presents challenges of its own during production. This situation mostly arises when cost-intensive products are being handled or when small amounts of ingredients already have a decisive influence on the final product. The new DIW-PE-GZD200 „Small Scale Feeder“ with its innovative details has been specially designed for the requirements of minor ingredient addition. The modern weighing system ensures highly accurate feeding results in connection with the twin-screw GZD 200 Loss-in-Weight Feeder.

The mass flow is virtually pulsation free. Conveying of…

Low segregation, low wear, low air and low energy consumption Our dense phase conveying systems with pressure vessels are designed for processes that require gentle conveying, low segregation, low wear, low air and energy consumption. Another advantage when using a dense phase conveying system with pressure vessels rather than a lean phase conveying systems with rotary valves is that no part rotates in the product stream. In lean phase conveying systems, the rotating rotary valve will cause fine metallic attrition when coming in contact with the housing and thereby contaminate the product. Another disadvantage is air leakage. This occurs because of the gap between the rotor and the housing. Due to wear on the rotary valves, the gap gets bigger which leads to increased leakage of air, reduced capacity, to conveying problems and pipe blockages. We designed the dense phase conveying system mini-double vessel PTAD20 to replace rotary valves in existing conveying plants. The Gericke dense phase conveying system mini-double vessel…

Daily production challenges Daily production challenges become critical where particularly low feed rates are required. This can either be due to the high cost of ingredients, or to the significance of accurate addition of small quantity of ingredients. The new DIW-PE-GLD87 Feeder has been designed for the requirements of minor ingredient addition. The latest weighing system technology, which is based on using electromagnetic strength compensation, put into operation in combination with the GLD87 High Accuracy Feeder, leads to extremely exact feeding results. The GLD87 is easy to clean and ideal for industrial applications. Perfect feeding results are achieved if high accuracy is required and products to be metered are very sluggish. This Small Scale Feeder is stable. In order to reduce adverse effects by external influences, the feeder can be supplied with wind shields, special connecting sleeves and vibration cushions and be combined with the fine adjustment possibilities of the Easydos Pro…

Pneumatic dense phase conveying systems for powders and granulates with pressure vessels are favored against lean phase conveying systems with rotary valves wherever one of the following criteria is important: - The products have a fragile surface structure and must be transported without any damage. - Mixtures should not segregate trough the transport. - The product is abrasive, meaning that there is danger of high wear of pipelines and of the installed components. - The consumption of air and thus the corresponding operating energy costs has to be reduced. The Gericke dense phase conveying systems can be operated with air starting velocities from 2 m/s depending on the product and on the application, in comparison to lean phase conveying systems with starting velocities from 20 m/s. The solids loading (= amount of kg of product that can be transported with 1 kg of conveying medium) in dense phase conveying systems can reach up to 150, whereas in lean phase…

On a centrifugal sifter, the bulk material is fed in a controlled flow into the cylindrical basket containing the sieve hose. Fast rotating blades push the product against the sieve and transport the oversize particles in an axial movement towards the oversize outlet. The fine particles pass through the sieve and are forwarded to the next process step. Centrifugal sifters are characterised by high throughput and compact design. A typical through put can vary between some 100 kg/hour and 60 tonnes/hour using an 800 micron mesh. Gericke have been manufacturing centrifugal sifters for more than 50 years. They are available in different ATEX categories. Sifters are used at the reception point of raw materials, e.g. after Big Bag emptying stations, sack tipping units or above filling and conditioning machines. Very low headroom is required by the Inline sifter, which can be placed anywhere in the pneumatic conveying line. Usually Nylon sieves are used. They are robust…

Many raw materials tend to create lumps during transporation or storage. The product loses his ability to be processed easily. Pneumatic conveying systems may get disturbed, feeder deliver inaccurate recipes and mixers cannot distribute the ingredients to a homogene concentration in the mixing chamber. To reduce the size of the agglomerates, Gericke offers a size reductor (Nibbler) for the reliable and quick particle size reduction. Gericke Nibblers treat the raw material gently and reduce blocs, lumps and agglomerates. Rotating paddles push the material through a screen. The rotation and angle of the paddles sweep the product against the serrated screen with the reduced particles passing through the holes. Size reduction is achieved by a cutting action (not grinding) and the breaking effect of brittle materials. The Nibbler works with a low peripheral tip speed avoiding the heating up of the products. Gericke Nibblers are available for the integration into different…
