The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced.

Ball Mill Introduction. Ball mill works on the principle of impact: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls.

From the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. Calculate the CSE as the average: (80.7 + 73.5) ÷ 2 = 77.1% + 75 μ. In this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. This means that

In the previous article we considered the method for determining the bulk weigh of new grinding media. Determination the grinding balls bulk weigh directly operating in a ball mill becomes necessary on practice. It is done in order to accurately definition the grinding ball mass during measuring in a ball mill and exclude the mill overloading with grinding balls possibility

Mill has a weighing device under the main mill, which indicates the weight of powder /oxide inside the mill .The feeding lead lumps amount depends on this weight. Pulsaire Collectors/Filters Lead oxide is harvested through a classifier high efficiency cyclone, bag-house filtration unit or Pulsaire collector and induction draft fan arrangement.
