Of simple, yet robust design, the precrushers series PG are especially suitable for reducing lumps or blocks of soft and medium-hard materials up to a size of a few centimetres.

They are mainly used to prepare materials that have to be ground or mechanically conveyed afterwards. The obtainable size is particularly suitable to feed mills configured in order to obtain higher fineness.
The allowed feeding size is of 35-40 cm Max. and the production capacity is up to 5 ton/h.

Roll Crusher – Series BI e TR

The smooth roll crushers are particularly suitable to obtain the most medium granules with low dust content, or to grind abrasive, moist, fibrous, heat sensitive products and materials with a tendency to melt.
The maximum allowed feed size for the crusher series BI is from 15 up to 30 mm and the production capacity is from 0,1 to 12 ton/h.
The crushers series TR represent an improvement of the series BI in that the addition of a third roll ensures a high size-reduction ratio. It is therefore possible to both precrush and grind on one mill only. Rotation speed of the rolls can be equal or different to meet several requirements.
TR crushers are designed for the production of medium/small granules (0,2 – 0,3 mm) having narrow granulometric distribution curve.
Both BI and TR crushers are equipped with a special spring device both to adjust grinding intensity and to return the roll in case metallic parts are accidentally fed.
