What is a granulate screening machine?

Granulate screening machines are used for screening all types of granulates. Granulate screening is a special and highly sophisticated form of control screening. During the production of granules, some granules may not be the same size. Our pellet screening machines help you to separate or screen this heterogeneous pellet from the remaining homogeneous pellet. These separate the pellets according to size and prepare them for further processing in pellet production. We offer overlength separators especially for plastic granulate. This allows you to screen excess length out of plastic pellets very efficiently and reliably.

How do pellet screening machines work?

How the granulate screening works

To ensure that the pellet screening machine can achieve the best screening results, its vibration frequency, screen panels and inclination are optimally adapted to your screened material. At the beginning of the screening process, the raw material is fed into the granulate screening machine. Thanks to our special feeding technology, the granulate is fed very evenly onto the screening machine. The granulate is then separated into different fractions by the screening machine for granulate using vibrations and oscillations. The screening result is the finest granulate, which you can use optimally.

Granulate screening of different materials

How can the pellet screening machine be adapted to material changes?

As a manufacturer of granulate screening machines, we know that parameters can sometimes change in the granulate production process. It is therefore important to us that your pellet screening machine can also handle these changed requirements. We design our screening machines for granulates in such a way that, for example, screen linings can be changed quickly and easily when changing materials. In this context, your employees can replace screen linings very quickly on site. At the same time, maintenance is easy. Both minimize any downtimes during pellet screening and pellet production.
