Screening

Looking for efficient screening solutions for waste management?

RPM offers a range of fines screening solutions to clean up trommel fines, particularly when used in conjunction with a density separator to separate the light fraction. We provide several options tailored to your specific needs.

Stretch Deck Screens

Construction and demolition waste often contain sand fractions. For small fractions like sand, RPM incorporates a stretch deck screen. Even when the materials are moist, a stretch deck screen can still screen at the desired mesh size without clogging.

Functioning of Stretch Deck Screens

Elastic polyurethane screen panels are alternately tensioned and relaxed, creating a “trampoline” effect. In the final tensioning phase, the screen panels are stretched, changing the surface of the screen mat. Acceleration forces of up to 50G are achieved, whereas the machine structure experiences only 2 or 3G.

Pearson Star Screens

The screen deck operates free from blinding, even with difficult feed materials. Star screens are also used for demolition and construction waste. RPM includes them as a secondary screening step, screening fractions from 10-50mm on adjustable star screening machines.

Functioning of Star Screens

The material to be screened is brought or falls onto the star screen. The rotating stars transport the material, and during this process, fines are removed by falling through the spacing between the fingers of the star or the spaces between the stars themselves. The oversized material is transported off the end of the star deck onto a belt conveyor or into a bay.
