Double Roll Crusher - Binder+Co
Binder+Co Double roll crusher. An optimum grain size of 10 to 50 mm is crucial for sensor-based sorting of cullet since a higher content of fines (0-10 mm) would have an unfavourable effect on sorting performance. In the form of the double roll crusher, Binder+Co has created the ideal prerequisite for the subsequent sorting of waste glass.

Crusher - Wikipedia
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore ), so that pieces of different composition ...
