dynamic dynamic load of ball mill

Rolling bearing calculation: analysis of the static and dynamic loads

Dynamic load The C loading capacity is the mechanical magnitude that allows us to calculate the rolling bearing's service life wich includes either axial or radial loads. The dynamic load varies in time, but knowing it will help us specify the bearing basic rating life. This is the main piece of data that you should specify in your project summary.

The degree of filling the mill with balls also influences productivity of the mill and milling efficiency. With excessive filling, the rising balls collide with falling ones. Generally, filling the mill by balls must not exceed 30-35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length.

If the hardness is lower than this range, the permissible load and nominal life will be decreased. For this reason, the basic dynamic load rating and the basic static load rating should be multiplied by hardness factor for rating calculation. See figure below. The hardness requirement of PMI linear guideway is above HRC58, thus the fH=1.0.
