Ball Mill Used In Minerals Processing Plant Prominer
this ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types: grid type ball mill and overflow type ball mill.jun 25, 2011 inr however MV vfd starts from range about 1.2 cr. inr. for ball mill starting torque requirement is very high about 0%. pull out torque requirement is also high about 250%. hence, while specifying ball mill motor, pull out torque is generally given as 250% without negative tolerance. above said conditions can be met by both lrs and MV vfd.ball mill working principle and main parts. -14 ball mill working principle.
