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.

This example describes the complexity of a screening technology project for a leading manufacturer of polycarbonate. For integration into a new production line at the Chinese production site, a screening solution away from the standard was sought. The solution: A JEL Freischwinger as a special design.

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.

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.

One processing step in the production of S-PVC is oversize separation and dust removal. Find out here how we solved this task with the JEL Freischwinger.

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.

The task was clear, the implementation challenging: the customer is planning to expand its existing production line for EPS granulate. However, space is at a premium. A task made for the JEL Regula Standard.

An internationally active fertilizer manufacturer was looking for a classifying screen that could withstand the abrasive properties of urea and deliver consistently high throughputs in the production of nitrogen fertilizer. And found the ideal screening solution in the JEL cantilever.

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.

Polymethylmethacrylat (PMMA) wird als Rohstoff für die Herstellung verschiedenster Endprodukte genutzt. Im Dental- und Sanitärkeramiksegment sind dabei konsistente Qualitäten in engen Spezifikationsgrenzen ein Muss. Eine Aufgabe für die Schwingsiebmaschine JEL Freischwinger.

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.
