The rule of thumb for the Double Roll Crusher’s ratio of reduction is 4:1. The simplified design gives these units excellent reliability and requires very little maintenance. The crushers are designed with built-in tramp relief that allows for the passing of uncrushable objects while remaining in continuous operation and returning to the initial product setting.

The action of a roll crusher, compared to the other crushers, is amenable to a level of analysis. Consider a spherical particle of radius r, being crushed by a pair of rolls of radius R, the gap between the rolls being 2a (Figure 6.15).If µ is the coefficient of friction between the rolls and the particle, θ is the angle formed by the tangents to the roll surfaces at

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.
