Very large tonnages can be ground with these ball mills because they are very effective material handling devices.Ball mills are rated by power rather than capacity.Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 mw toromocho, private communications.Get Price
The cylindrical jar is used as a mill that would rotate the material that about to be ground, a motor is used to power the system so that the jar can rotate in high speed and using the regulator.
To determine the size of mill required based on throughput, and therefore motor power.The standard bond ball mill work index test procedure is firstly to stage crush the feed to minus 3.35mm, and size a representative sample.The test then involves a series of batch grinds in a standard bond mill.A bond mill is 0.
