Roll Crushers

 · Power Consumption of HPGR. As a general rule, motor power is the product of capacity and energy input. For HPGR we have seen that the energy input is defined as the specific energy input. In conventional work, Bond''s work index is usually accepted as the measure of the net specific energy required for comminution.
