Bulk solids and plant technology: practical reports and tips

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.

Customers often present us with exciting challenges. This was also the case for a manufacturer from the pharmaceutical industry who was looking for a solution for dust-free big bag emptying for its lactose production, with which it is possible to switch between two different downstream processes.

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.

Screening pellets – sounds comparatively simple. However, when it comes to pharmaceutical pellets in sensitive production environments, it quickly becomes challenging.

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.

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.

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.

Centrifuges are usually used to separate solids from suspensions. However: Vibration screening machines such as the JEL VibSpeed can also achieve perfect results, as this practical example from the pharmaceutical industry shows.
