Estimation of motor power output for crushing by screen hammer
We need a 'comparison' scale by which we can estimate motor power output matching the maximum crushing capacity. 73 Electric energy consumption for The impact crusher (Fig. 13.15) employs high-speed impact or sharp blows to the free-falling feed rather than compression or abrasion. It utilizes hinged or fixed heavy metal Crusher an overview ScienceDirect Topics

Estimation of motor power output for crushing by screen hammer mills
When the motor output (kW) of a mill is large compared with the maximum crushing capacity of a mill, the maximum crushing capacity will be decided by two factors. The first factor is the maximum hold-up H". max in the mill. The second factor is the mean residence time t through the mill. Maximum crushing capacity of a mill 72 Figure 1.shanghai shibang crusher.
