Explain the role of ball mill in mineral industry and why it is extensively used. Describe different types of ball mill design. ... Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore.
There is no general, allpurpose ball in our product range because there are no generic processing plants. The size of grinding media plays a key role in overall performance of the grinding circuit. Larger grinding media has a smaller grinding surface area, but .
Jul 01, 2003· Grinding Media Size Effect The ability to operate a mill with smallerdiameter grinding media greatly increases the mill''s efficiency and can overall further increase the quality of product through finer grinding. However, smaller grinding beads are more prone to hydraulic packing due to their decrease in mass per bead.
In this article, alternative forms of optimizing the milling efficiency of a laboratory scale ball mill by varying the grinding media size distribution and the feed material particle size distribution were investigated. Silica ore was used as the test material. ... These play a major role as gradation of media is influenced mostly by particle ...
Grinding media consumption is one of the major operating costs in mineral processing industry; it was found that the consumption of media in ball mills during grinding operation can be up to 50% ...
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
