Dust emissions during ship loading are often a burden on the environment. It is possible to minimise dust emissions by fairly simple means. When loading ships, product flows down a loading pipe from a great height and gains a lot of speed. When the material flow collides with the product mountain in the ship’s hold, a lot of energy is released. This leads to violent movement of the material, which can stir up a lot of dust. The loading pipe (or loading conveyor) is often telescopic and pivoting, in order to load the vessel as efficiently as possible. Sometimes a dump pipe is used, equipped with a loading bellows at the end. To minimise dust generation, two basic solutions are possible, which can also be applied in combination: * A sealing of the product surface and possible extraction. * A speed reduction of the material flow from the loading pipe. Reducing dust emissions with dust skirt An example of closure is the deployment of a dust skirt under the spout. An automatic height adjustment ensures that the skirt rests on the product surface. A well-designed dust skirt is very effective, especially

How can you use your expensive soil economically efficient? This is possible with a bucket elevator. If you raise your product with an elevator to a height of, for example, 30 meters, you only need a ground surface of approximately 2 m². A belt conveyor quickly reaches a length of 60 meters, with supports the surface area needed will easily be 120 m². What you need for a bucket elevator * a good foundation * a metered supply of product * lateral support per 10 meter height Suitable means of transport The bucket elevator has already proven its value as an extremely reliable means of transport for the transport of dry materials such as grains and flours. Due to the development and application of rubber belts and plastic inserts, there is hardly any elongation and the powers to be transferred have been greatly improved. Because of this and the use of modern plastic cups, the elevator is also very suitable as a means of transport for sand, gravel and other abrasive

Long service life and lower energy consumption by using a plastic base plate. 15 year of mais conveying proves the benefits. By applying a complete plastic wear plate to the base of the chain conveyor, a long service life of the base is achieved. The chain is supported over the entire surface and not only glides over the chain links, but the flights also carry along. Energy consumption has been shown to be around 20 % lower than with other systems. The friction of the product over the plastic is lower than over steel. An example of the service life We supplied chain conveyors to Tate & Lyle for their maize soaking tubs. After 15 years, we had to replace the plastic floor of the main distribution chain. There, 1,300 tonnes of maize are handled every day, 340 days a year, which is almost 5 million tonnes in total, and only then is the first simple maintenance of the plastic parts required. Maize contains a lot of sand and abrasive material.

During transport of bulk solids dust is often released. Under health and safety regulations, companies are obliged to take action against this. A high concentration of dust A high concentration of dust particles quickly leads to you having to take measures to combat dust. Simply handing out face masks is completely inadequate. More needs to be done. The government has stipulated how high the dust concentration may be in a room for each type of substance. If the inspection authorities identify that a room contains too much dust, they are obliged to take action. No need for expensive installations right from the start Fortunately, it is not necessary to buy an expensive extraction system straight away. Sometimes it is perfectly possible to adapt the product, business process or machine so that less dust is released. Contaminated air flow If all this is not enough, it is time to think about a way to eliminate the dust. If you opt for a system that extracts the dust via a filter, you can expect a polluted airflow. There are also regulations on how high the emissions may be. Particularly strict regulations apply to hazardous substances

Jansen&Heuning designed a logistic system for the processing of blood meal, meat meal and feather meal. Contamination was an important issue. For abattoir waste processor Noblesse, our engineers studied the processing of blood meal, meat meal and feather meal. In this process, contamination, among other things, had to be taken into account. How did they do this? At Noblesse proteins the existing production site had to be improved in terms of storage and loading. The available height is 11,000 mm at the ridge and 9,500 mm at the wall, the width of tents is 45,000 mm. The main challenge for our engineers was that it had to be possible to mix from all of the silos. In addition, we had to ensure two completely separate lines to prevent contamination. Finally, all silos had to be placed on load cells for the correct dosage. Objectives * Storage capacity: feather meal 300 tons; meat meal 600 tons; blood meal 60 tons * Loading with movable conveyor above the cars with loading bellows * loading with a capacity of 60-80 tons/hour The system consists of: * new silo block consisting of five silos of over

In the Western Docklands of Amsterdam, ICL Amsterdam is located. This factory annually produces approximately 550,000 tons of high quality potassium and phosphate fertilizers. To improve the production line of ground phosphate, Jansen&Heuning modified the transport system. The work consisted of: * Replacing the old silo/delivery of a new silo * Extension of the existing elevator * Delivery of drop tubes/replacement of old drop tubes * Delivery of a new transport screw * Adjustment of the floors * adapting existing pipework

Diameter 800 mm; capacity 150 tonnes/hour; length 13 meter; rotating around its central inlet point. A unique screw conveyor. Jansen&Heuning designed a screw conveyor to transport sugar for sugar beet company Cosun in Hoogkerk. Cosun Beet Company aims to be the greenest and the most innovative sugar beet processor in the world and our engineers got a chance to contribute to this goal. The sugar is transported to the silos with a transportation system. All sugar is stored in four large silos where each silo is divided into 3 compartments: the core, the inner ring and the outer ring. These compartments are filled evenly. Formerly, the silos were filled using a mobile conveyor belt, however, such a system is never 100% clean and is sensitive to errors. Therefore, our engineers designed a rotating screw conveyor. The screw rests on a slewing ring and a wheelset in the middle, that moves the machine around. The screw conveyor has a diameter of 800 mm and is completely made of stainless steel 304. The filling capacity is approximately 150 tonnes/hour. With a length of 13 meter, this is a

Jansen&Heuning installed a pre-cleaner with cyclone installation for plastic recycling and compounding company REK Europe B.V. in Oosterhout (NL). REK Europe uses plastic waste which they process into high-quality raw materials for plastics processing companies, by grinding, homogenizing and compounding the plastic waste. After installing the pre-cleaner, the existing frame had to be modified. Therefore, Jansen&Heuning made a separate frame for the cyclone with accompanying filter bags, so that a big bag could be placed under the cyclone and the filter bags could be easily unloaded. The hard particles from the extracted product can be loaded into big bags and the remaining air is filtered with filter bags. The pre-cleaner works well and removes about 99% of the angel hair from the plastic granule: a successful project.

A new product in the big bag crusher range of JH. It has proven to be a very successful alternative between the mobile crusher and the fully automatic crusher. The content of big bags can become hard for many reasons. In that case, it is not possible to empty the big bag in a normal way, because the lumps are too big. By crushing the content, the large lumps are reduced to a workable size. Scope of the installation * crusher arms * frame at height * removable shield * radio remote control for the forklift driver * hydraulic unit * the entire frame can be easily moved with a forklift Operation The big bag crusher semi-automatic can be operated as following: a big bag hang with its loops on a forklift and is loaded into the crusher form the top. The crushing usually starts from the top and moves its way down to 4 to 5 places distributed over the height of the bag, the forklift thus lowers the big bag downwards. A crush movement of the big bag crusher lasts approximately 10 seconds. This cycle may be repeated after rotating the big bag 90 degrees , this ensures that all large chunks in the big bags are broken. Hydraulic

Jansen&Heuning made a smart modification to an existing big bag filling station, thus creating fully filled, stable big bags of 2 meters high. Most big bags are slightly over meters high. But how do you ensure a good big bag filling process and stable big bags when they are almost 2 metres high? With this question, HSR Packaging from Ede (NL) came to Jansen&Heuning. We started working on a smart modification of the existing big bag filling station: a big bag fill- and shake station in one. The problem: unstable, poorly filled big bags The big bags at HSR Verpakkingen are almost 2 meters high and are filled with various recycling products. The client noticed that big bags could not be filled fully with the old big bag filling station, because the contents were loosely added to the big bags. In addition, they noticed that the filled big bags did not stand very stable on the pallets, which is necessary with big bags of almost 2 meters high. The solution: bigbag shaking and filling station in one Jansen&Heuning designed a modification of the existing big bag filling stations by adding a big bag shaking

Cameras are used to analyze the colour of each grain of rice individually. With compressed air, each rice grain is then blown into the correct output. Jansen&Heuning has delivered and installed a sorting installation for Manglie, a rice farm in Suriname. It is not the first project Jansen&Heuning carried out for Manglie; earlier they delivered a transport system for loading fertilizer into airplanes. In 2021 our engineers delivered an optical sorter ‘Cimbria SEA TRUE’, two elevators of 10 and 12 meters, a self-made pneumatic two-way valve, an exhaust system and all supplies and parts for these machines. Sorting grains of rice by colour The optical sorting machine is applied in the flow of rice. Cameras are used to analyze the colour of each grain of rice individually. With compressed air, each rice grain is then blown into the correct output. The use of the sorter leads to good composition and therefore to a better final product. The two elevators take care of the supply and discharge of the sorter. The extraction system (fan and cyclone) extracts the dust from the process for the proper operation of

Jansen&Heuning have developed a series of spreading boxes for CIREX, to evenly spread ceramic powders on a wax model. The innovative installations contribute to optimizing the production process and improving the quality of the cast, steel and metal components. Steel and metal foundry CIREX bv manufactures complex components for global industry; from knife heads and pump parts to transport wheels and sensor housing. These are often high-tech components that must comply with class D3 tolerances, as laid down in the internationally recognized German standard VDG-P690. CIREX uses the ‘lost wax model’ method to produce the precision castings. Wax Tree One of the many process steps in the ‘lost wax model’ method is that a ‘wax tree’ -which consists of a series of wax molds-is coated with a ceramic layer, to eventually arrive at a cast result. The wax tree is imersed in a slurry, raised and then dusted with a ceramic powder (a type of sand), followed by a drying process. This is a cycle that repeats itself seven to nine times. Finally a refractory, ceramic mantle is formed

Jansen&Heuning recently delivered the screw conveyors for the gypsum silo project of Eurosilo (ESI) in Serbia. ESI has a silo solution that combines three logistic functions at the smalles possible footprint: dewatering, storage and load out. And all that fully automatically. The filling screws, screw frames, excavating and spreader screw and the eviscerating screw are manufactured by us on the basis of demanding productions specifications. Some screws have a special non stick coating. In addition, the construction is provided with a special paint system. In short, a high-quality product that fits perfectly with the competences of Jansen&Heuning.

HVC tries to give waste a new life. The waste that can not be processed further, is converted into electricity, heat or green gas. The installation in Purmerend makes compost of organic waste and food leftovers from the green container for fertilizing gardens. Jansen&Heuning has modified the existing installation at HVC Purmerend, whereby an extra screening installation has been built in. This will improve the quality of the compost. The adjustment to the installation consists of screw conveyors JHS500, conveyor belts and platforms. Since the existing installation had to be adjusted, our engineering measured the entire process and worked it out in 3D in order to achieve an optimal connection with the existing installation. “The reason for this investment was to improve the quality of the compost. The cooperation with Jansen&Heuning went well; there was proper consultation and we were able to help each other well. The installation is also doing well; the quality of

JHBB300 loading bellow for Alpuro Breeding Jansen&Heuning has deliverd a loading bellow to Alpuro in Uddel, the Netherlands. Alpuro Breeding provides the livestock former everything he/she needs for a successful calf breeding. Alpuro was looking for a loading bellow for both the discharge in open trucks and bulk trucks. Reason for the replacement of the existing bellows was the dust that the installation produced. The biggest challenge was the installation dimensions; the loading bellow should not be more than 850 mm high in retracted position, while the stroke of the loading bellow should be at least 2.100 mm. Furthermore, the loading bellow is equipped with a capacitive sensor that automatically follow the product level. The customer is very satisfied with our product and the technically very compact solution.

For our client CWT Commodities (Amsterdam) BV we place new lines of supply for cocoa beans at Dutch Cacoa in Amsterdam. The project consists of 21 silos and 42 chains. The silos have a capacity of 56 m³ each and are places in two rows, one of 11 and one of 10. - capacity: 100 m³ / hour / 50 tons per hour - operating hours: app. 30.000 per year - product: cacoa - practical bulk density: 550 kg / m³

Despite the heat, our technicians Harald Ozinga and Gerke Mulder have installed the JHE528 Elevator at ICL in Heerlen. The elevator has a capacity of 60 m³/hour and transports fertilizers.

A handful among the projects / deliveries of the past few weeks

Jansen&Heuning has installed a 16 meter high silo in Hoogezand (NL) within 8 hours. This was possible, because the silo was completely designed in 3D and prefabricated with laser-cut parts. But also because the silo was aligned and installed with a top team of three mechanics and professionals of Mammoet. As such, the total construction could continue undisturbed. The silo with a capacity of 180 tons is part of a new kiln system. Our client NEG Glass Fiber will start to use the silo soon to increase the producten of high-quality glass fibers.

Tate & Lyle bought a series of chain conveyors from Jansen&Heuning in 2003 for filling their soaking tubs with corn. In continuous operation the chain conveyors have transported thousands of tons of corn, which caused some wear after 15 years. Replacement by stainless steel was possible, but had to be performed in just 2,5 days due to the great pressure on production. The four Jansen&Heuning mechanics managed to do this within the set time by working hard, using their experience and of course an optimal preparation.

The first parts of the conveyor belts designed and produced by Jansen&Heuning are transported to the Eemshaven with Convoi Exeptionnel. There they are used for the sustainable use of the power plant of RWE. Herewith up to 20% biomass (wood chips) can be added as sustainable fuel for the 2 power generators, each with a power of more than 700 MegaWatt. These belts are in total 300 meters long and have a capacity of 1600 m³ per hour. We are proud that we, as a company from Groningen, can make an important contribution to this energy transition!

Mechtler GmbH Landesproduktenhandel is based in Austria and has recently purchased a roller sorter. They wanted one extra and ended up at Jansen&Heuning via the internet. ”I asked for a quotation via the website and had nice contact with Jansen&Heuning since then. The collaboration worked well.” The company concentrates on the production and trade of agricultural products such as grain, seeds, fertilizer and potatoes. A potato roller sorter is indispensable in their processes. Werner Rannert: ”The sorter works well. Once the machine is properly set up, it is very easy to operate”.

Close to Rihyad (Saudi Arabia) a feed mill is being built that will feed 70.000 cows every day. Jansen&Heuning supplied all elevators, chain conveyors, screw conveyors and paddle mixers. For Jansen&Heuning this is the largest project outside the European Union so far. The factory will be put into operation at the end of this year. On the photo you see the two mixers at the bottom left. On the right the elevators.

In principle, a machine factory can produce everything if the material is made of steel or plastic. However, an all-round machine factory is almost a rarity. Many machine factories have their own specialization, focus or trademark. Jansen&Heuning as well. We produce bulk conveyors and special equipment such as mixers, but what really characterizes our company is smartly combining our own ánd imported machines. In this manner, we created a custom made compact unit for De Heus Voeders B.V. for the optimal production of cleaned and crushed grain. The installation consists of a windsifter, a double-deck sieve and a crusher. Jansen&Heuning has gained a lot of knowledge and experience over the years in the storage and handling of grain. At all times, our special sales team is ready to answer your questions, no matter how diverse. We are happy to help you, so please give us a call!

These JHMX10000 mixers can each mix 45 tons per hour, and have each a net capacity of 10.000 dm³. The power is 110 kW.

Jansen&Heuning supplies a fully automated feed installation Jansen&Heuning supplies a fully automated feed installation for a dairy farm in Saudi Arabia. Two newly developed concentrates mixers, each with a drive of 110 kW, are the heart of this installation. For the 70.000 cows on the farm, each mixer mixes 10 m³ (4,5 ton) of feed every six minutes. Thirteen different nutrients and minerals are carefully weighed before they enter the mixer. And because cows also have a good taste, a bit of palm oil is added. We hope they enjoy it in the desert

fully automac filling of FIBCs A movie about our new FIBC shows the latest invention in the world of FIBC handling. The construction of this new FIBC allows fully automatic take up from a pile and filling them by a spout. Jansen & Heuning won the Process Innovation Award 2010 at the Dutch exhibition at Utrecht in October 2010.

Traditionally, the province Groningen has always been an area of grain cultivation. The cooperation Agrifirm receives, stores, dries and cleans the grain for her members. This happens in different establishments among which is Delfzijl. Over the years the capacity of the drier became insufficient. We supplied two new driers with strainers with a capacity of 25 tons/hour, a couple of chain conveyors and readjusted the existing installation. Long before the harvesting of the grain everything was installed and fully functional. Although the nice summer made sure the new equipment hasn’t seen a lot of action yet.

We believe that innovation is the key to surviving any crisis. That is why we keep investing in new equipment. Such as our new CNC plasma cutting machine, that can handle plates up to 30 mm thickness and a pressbrake, which supplies a pressure of 1.800 kN.

At Hengelo the production of salt is steadily growing. Jansen & Heuning received the order for the renovation of a number of big belt conveyors, including the gantry`s. The production will only be available for the erection for no more than 6 days. These type of orders give Jansen & Heuning the chance to show their experience and professional way of detailed hourly planning.

Glue producer Paramelt rationalized her production using only one big mixer instead of 4. Jansen & Heuning designed, produced and installed the complete project, including bagging units for valve bags and FIBC`s. Usable existing machines were put back in operation in the new situation.
