Hammer Mills : An Engineering Overview. What Is It ? How

If the mill is used as a crusher, which means that the particle size diameter of the finished product is quite coarse ( 1 mm), then the mill can be discharged by gravity. however, for finer target sizes, requiring very high speed and thus moving a lot of air, the final product can be transferred pneumatically.

Milling Parameters

The end mill speed is calculated with the following formula: n [rpm] = (vc [m/min] *1000) / 3.14 * d1 [mm]) example calculation: vc = 500 m/min (selected from chart) d = 8 mm 19904 rpm = (500 *1000) / (3.14 * 8). if the maximum speed of the milling motor is lower than the calculated value, the maximum speed of the milling motor needs to be inserted into the formula for the .
