Double-roll crushers offer up to a 3:1 reduction ratio in some applications, depending on the characteristics of the material. Triple-roll crushers offer up to a 6:1 reduction. As a compressive crusher, the roll crusher is well suited to extremely hard and abrasive materials.

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 ...
