Primus

Hopper interface

Steep side walls in the hopper itself prevent the risk of material bridging. Flow is guaranteed even with wet material. A mechanical straight line controller automatically keeps the hopper belt in the required position.

Reliable drum cleaning

A freely revolving circular brush, configurable from below, is used to clean the screen drum. The position opposite the screen side presents no risk of contamination by the screen material.

Conveying material

In its base configuration, every screen machine has a sturdy cleated V-belt for the fine particle and, for the oversized particle, a smooth belt with screwed-on, exchangeable cleats that minimise rolling back of cubic fractions. With a belt extension, the usable delivery height of the discharge belts on the Primus increases to almost 3 metres.

Separating off the coarse

When working with excavated material, gravel or lightweight building rubble, a hopper pre-screen prevents possible damage caused by solid contraries. The sturdy coarse material grid is hydraulically hingeable via radio remote control and has a chute for deflection of contraries alongside the machine.
