Bulk solids and plant technology: practical reports and tips

When processing plastic powders, agglomerates are often formed during drying processes. How, with the integration of the JEL PS passing sieve, the powder is now transferred lump-free to the next process step – you can find out here.

Not every bulk material can be discharged from its container without difficulty. This can quickly become a challenge. Engelsmann product developer Viktor Quindt gives tips for efficient and residue-free discharge and an outlook on developments in the coming years.

With free-fall mixers, the mixing effect is created by setting the entire mixing vessel in motion – usually by rotating or tumbling. Constructed according to hygienic design criteria, the JEL RRM can also be used in hygiene-sensitive industries.

A manufacturer of plastic granules kept receiving inquiries about smaller product quantities. However, setting up a separate production line with small-bag filling was not worth the effort. Today, new customers are being won with a mobile filling system that can also complement existing big bag filling stations.

In order not to contaminate individual product batches and production plants during the processing of delivered PVC powders into high-quality plastic profiles, a plastics producer requires an upstream protective screen that removes foreign bodies before silo filling – the JEL TWS tanker screen.

Multifunction station for emptying lactose from big bags. With integrated protective screening.

Whether for chemicals, cosmetics, pharmaceuticals, food or animal feed: a globally active contract packer doses, fills and packs across all industries. The new system for big bag emptying with matching conveyor technology should therefore be adaptable to a wide range of products and take up little space.

You know the situation: when working with bulk material, agglomerates and lumps are not uncommon. We have compiled a list of screening and crushing machines that can help in such cases. Always with the product in mind, because that’s what matters.

Besides round sieves, rectangular screening machines can also be used in plants with the highest hygiene requirements – as long as they are constructed according to the basic principles of hygienic design. If this is the case, they even offer interesting advantages over their round relatives.

The practical example with the JEL EasyVib describes how screening machines can be used to achieve optimum dedusting of animal feed pellets and which aspects plant operators must consider when selecting a suitable screening process.

Cocoa as a raw material is demanding, especially when oils and fats escape during processing. This also puts the screening technology used to the test. Read here how the JEL Viro proves itself here.

Sieving nuts: In addition to a screening process that is gentle on the product without affecting quality and consistency, the screening machine must also manage the required production volume. The special buffering system of the JEL Freischwinger efficiently prevents the formation of plugged-in grains.

Coffee products, functional foods, snacks, but also baby food and personal care: as an important process step in production, bulk goods such as milk powder, sugar and other products are processed into homogeneous mixtures by this customer. Ideally suited for this: the JEL CM container mixer.

Containment systems for big bag emptying include single-use or disposable film systems. What level of safety do these systems offer? Where are critical points in the maintenance of the containment? And what demands are made on the operating personnel? You can find out here.

Various types of tea are to be freed from small dust particles and breakage as well as from larger foreign bodies before packaging – and this as gently as possible. Find out how we solved the task with the JEL Freischwinger linear stroke screening machine in this project example.

Protective screenings are one of the most common screening processes in industrial manufacturing processes. Why this process step is so enormously important and what makes good protective screening machine, we have compiled for you here.
