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.
In contrast to a Double Roll Crusher, the basic concept of the Mineral Sizer is the use of two rolls with smaller diameter shafts, because of the operation at a lower rotational speed by a direct high torque drive system. This design produces three major principles which all interact when breaking materials using sizer technology.
