Our MULTISTAR – star screen technology

Screening is an elementary treatment step in the conditioning of waste, recyclable materials and biomass. The star screen technology is increasingly used for this purpose. And in most cases the star screen used is a MULTISTAR. The reason why can be easily explained: With the exact screening process it takes just one machine and one work step to divide the screening material into 2 or 3 fractions. Both the throughput capacity and the separating accuracy remain unchanged - due to the patented CLEANSTAR cleaning system.

The grain size can be adjusted by just simply pressing a button - the rest is done by the machine. Due to the highly efficient drive, screening runs quietly, reliably and economically.


The MULTISTAR technology is exclusively available from our sales partner KOMPTECH.

You will find the right equipment for almost any application and plant size. Extensions like e.g. magnetic separation, wind sifter or rolling body separation make the screening system multi-functional - everything is possible.

The functional principle: First coarse - then fine

Depending on the design, the interior of the star screen machines consists of one or two screen decks. The rotating shafts of the coarse screen deck convey the material in horizontal direction. Everything that cannot pass through the space between the stars, is separated as coarse grain material and transported further. The material that passes through the screen drops onto the fine screen deck equipped with smaller stars, and is then divided into a fine and a medium fraction by using the same principle. The coarse screening before fine screening principle produces a high screening quality, enables high screening performance with a short screen length and protects the fine screen against solid impurities.

The grain size is changed by adjusting the rotary speed of the star shafts. From the control panel and via frequency converters the grain size can be changed within the band width determined by the star geometry in just a few seconds. A central control monitors all functions and informs about the current operating status.
