May 22 2019 · The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

  • Analysis of ball mill grinding operation using mill power

    Analysis of a large amount of batch ball mill grinding data available in the literature has shown that the values of the power specific absolute rate of grinding of the topmost size fraction S and the power specific absolute rate of production of −100 mesh fines F are not independent of the mill operating conditions and mill diameter by mill operating parameters. It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters. Mill speed mill charge ball size and wet grinding are the parameters which have been selected for the present study. It is hoped that the analysis of the

    Working Principle Operation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill for example a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the Normal Ball Mill and Grinding Circuit Operation After the grinding circuit has been brought up to normal operating conditions the operator must monitor the various process variables and alarms. Most of these variables are monitored in the mill control room however the operator is also required to sample and analyse process streams and read
