The powder screening system.
The powder screening system.

The new screening concept is suitable  for smaller and medium-sized companies that wish to  carry out  quality controls on powders. It makes it possible to  screen fine powders (≤ 100 mµ, 250 mµ or 1000 mµ) at very high throughput rates (up to 30 to 40 tons per hour), ensuring that the end product complies with the desired justifications. The new screening system is based on a centrifugal screen, whereby the powders being processed are introduced into the screening chamber via a special built-in transport system and then suspended via rotating blades. The centrifugal force ensures that larger particles are immediately transported onwards and removed whereas finer particles are allowed to pass through the appropriate screen. Depending upon the specific product, process and capacity desired, it is also possible to work with a flat screen. 

By using various combinations of rotational speed, screen perforation size, and screen length, almost any desired screening result can be realized. Screening throughput rates of up to 15 or even 70 tons per hour can be realized, and even the very finest powders, from 5µ to 1000 µ, can be processed.
