A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser works on the principle of impact and attrition: 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 rotati

wear resistant grinding media ste el ball for mining. A discussion on the measurement of grinding media wear . A survey found out that approximately 53% of the grinding circuits around the world use ball mills, and 38% use autogenous or semiautogenous grinding, and therefore nearly 90% of mining operations are users of balls as grinding media .
There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
grinding media wear data pdf. Evaluation of grinding media wear 1 Introduction Wearrate is one of the most important factors when evaluating the overall performance of grinding media Therefore, extensive tests on media wear have been carried out by many media suppliers, users and labs (Berthiaux et al, 1996, Blecher et al, 1996a, Blecher et al, 1996b, Blickensderfer and Tylczak, 1989, Frances ...

Ball hardness is in the 60–67 HRC range. They wear better than 440C stainless steel and throughhardened carbon steel. They are also recommended for applications where a throughhardened steel ball is needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finish to reduce rust due to humidity.

As a result, the inherent wear rate of martensitic balls increases slightly at the ball becomes smaller. Therefore, for a given ball mill with a constant wear law, the resultant seasoned 76 mm martensitic ball chart should contain more large balls, fewer small : balls, and less surface area than a seasoned charge of 76 mm pearlitic carbon steel ...
