Once the dust settles: Cement plants develop sustainable concepts with Scrapetec innovations for conveyor transfer points. Downtime, cleaning costs, maintenance, wear and tear of materials or health risks for employees - the cost factors relating to the transfer points of conveyor systems are not unknown, but usually go unnoticed. Whether in mining, in the production of gypsum or cement. As a result of the cooperation with ScrapeTec, cement plants in Germany have now increasingly discovered the special sustainable effect of the new conveyor skirting for chutes. Manufacturer ScrapeTec does a kind of persuasion with this innovation. In the first step, usually 1-2 transfer points on the customer’s system are equipped with the new non-contact sidesealing. Then comes the work on the fly. The AirScrape conveyor skirting is convincing at first glance, because of the clean working method without dust, spill and maintenance compared to conventionally equipped transfer points. And after 3 months at the latest, the investment has already paid for itself because of the eliminated cleaning and maintenance…

New valve bagging machine for wheat flour for Hedwigsburger Okermühle GmbH Hedwigsburger Okermühle GmbH in Germany is one of the oldest mills still in operation. It dates from 1318 and has had uninterrupted activity since 1820. Okermühle contacted their partner, SSB Wägetechnik GmbH for a new valve bagging machine for wheat flour. Together we designed their new line, which is a fully automatic installation consisting of an automatic bag presenter and a fluidization bagging machine. The flour is introduced by gravity into a chamber in which a stream of air from the bottom fluidizes the flour. Another flow of air from the top of the chamber conveys the product into the bag. The fluidization system is the ideal technique for food products as it is very easy to clean, control and maintain. It facilitates a perfect cleaning of the whole bagging equipment in between different productions. Once the bag is full, the valve is thermo-sealed by two ultrasonic bars. The result is a perfectly airtight bag with good protection against any external…

Dry bulk solids in large containers poses the risk of overfilling and dust explosions. Correct pressure relief must be ensured. When dry bulk solids are stored in closed containers, there is not only a risk of overfilling, but also a risk of dust explosions. The correct pressure relief must always be ensured, and at the same time the fill level must not become too high. Many operators make do with reinforced walls and other devices in case of an explosion. To prevent such an incident from happening in the first place, the only safe solution is to continuously monitor the fill level in industrial transport and storage processes. View MBA888 "Ensuring permanent accurate control requires continuous improvement processes in measurement technology," knows Frank Wengler, senior product manager and one of the engineers at MBA Instruments. "Only in this way have the rotating paddle detectors from MBA Instruments met the current highest standards in demanding measurement tasks for more than 70 years - not least for the safety of man and machine."

A large grain storage facility in the south of England required a reliable content measuring device to replace an old acoustic wave system which was no longer functioning. Non-contact continuous level measurement UWT (UK) Limited proposed the use of the free-radiating radar NivoRadar® NR 3100 which could be supplied with an aiming flange. The integrated aiming flange allowed the radar to be mounted in the same position as the previous acoustic wave device which was close to the silo side wall and which allowed for the narrow 4˚ beam to be aimed towards the lowest point of the silo. This saved the customer time and money as they didn’t need to move the mounting position towards the centre of the silo where the silo was filled from. Bring the levels to where the planner needs them The visualising system that the customer had been using previously was very basic and limited and did not allow them to display the contents in any other way than the level of the material. The customer required the contents of the silo to be displayed in tonnes or percentage of fill. The NivoTec® NT 4600 with cabinet mounted digital display fulfilled…

Explosion isolation systems form part of the measures for explosion protection and are a must in every safety concept for process engineering plants such as silos, mills, filters and conveyors. Explosion isolation is absolutely essential for comprehensive explosion protection. Without isolation, an explosion safety concept is not only incomplete, but is also a waste of money. In almost every production facility, individual plant components are interconnected by means of pipelines. The purpose of explosion isolation is to seal these pipelines in the event of an explosion to prevent the propagation of pressure and flames, thereby protecting the adjacent plant components. Precompression and flame jet ignition increase the severity of the explosion in the connected vessels. This leads to secondary explosions that can cause even more catastrophic damage. Isolation systems prevent an explosion from propagating, thereby reducing the effects of the explosion to a minimum. Adjacent system components are optimally protected. A distinction is made between active and passive isolation systems: Active systems use sensors or detectors to detect an explosion as…

Elevator design for recycled asphalt planings (RAP). Recommending speed, power, shaft & casing sizes, and component specs (SPS steel buckets & NBR belting) Challenge Asphalt is made from a mixture of aggregates, binder and filler, and is commonly used in constructing and maintaining roads surfaces. When the surface layer of tarmacked areas is removed, the resulting waste material known as planings, can be recycled and reused. BG Europa Ltd approached 4B Braime requesting technical advice on the manufacture of a new bucket & belt elevator to be installed at an Asphalt plant in South Wales. Although familiar with bucket & chain elevators, the customer had no technical experience with buckets & belts so requested the expertise of 4B Engineers. The bucket elevator would elevate RAP (Recycled Asphalt Planings), and use a belt instead of chain, and standard 4B pressed buckets instead of fabricated buckets commonly used in the construction industry. 4B Braime were asked to provide a design proposal detailing suitable speed, power requirements, shaft & casing sizes, and component specifications to achieve the desired…

Flow in a silo can be promoted with a hammer. But the use of pneumatic knockers is a much better way. This gives maximum impact, without damage. APPLICATION The Pneumatic Knocker is used for bulk goods with flow problems, such as bridging, funnel flow and stagnant zones, when high speed shakers and vibrators with soft sine-shaped oscillations are no longer effective. Better than a hammer The effect of the knocker is comparable to the infamous "silo hammer", but without the damage a hammer can do. Dents by hammers wil complicate the material flow even more. And cracks and ruptures can also occur. The effectiveness of the knocker is evaluated according to the following rule: If the product can be knocked off or made to flow with a hand hammer, the Pneumatic Knocker is also effective. Mounting of the knocker The knocker is normally controlled by an electrical control system with a solenoid valve. Within the area where the knocking takes place there should be enough space for the impact to expand in all directions. Reinforcements of the silo walls and additional ribs should be avoided, as this increases…

How the Glatt Group implements contract manufacturing with expertise and innovative solutions There are many reasons for outsourcing production - minimizing one’s own risks or a lack of expertise in alternative technologies are just two of them.
