In the ball mill Lead is converted to Lead Oxide by grinding and oxidation process which is an exothermic process. In this process heat is generated and temperature of oxide is increased to control the temperature with in the operating range of 115 to 135C the ball mill temperature is controlled with constant flow of air and with the Enter the width of a mill shell liner. Note this is not the width of a lifter You may use the Mill Liner Effective Width calculation to determine this value. The mill critical speed will be calculated based on the diameter (above) less twice this shell liner width. Mill Actual RPM Enter the measured mill rotation in revolutions per minute.

• ### Calculate Ball Mill Grinding Capacity

The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent.
