Présentation

The roller grizzly can be used for argillaceous or plugging materials. It is set up between an apron feeder and a crusher. This device is perfectly adapted to be mounted with Py primary crushers and it significantly improves pre-screening.

The grizzly can be driven by a set of pinions and chains or just by a single chain.
