The article analyzes virtual experiments of the lining of a ball-type drum mill depending on a number of factors: the diameter of a mill, the diameter of grinding bodies, the number and height of liner lifters. The numerical experiment was performed using the EDEM software; a parametric model of the mill housing with variable liner lifters was created and imported, studies were …


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


The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).


As the ball wear rate depends directly upon the surface of the media charge, small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill could also be an issue. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is highly

The ball mill jar is loaded with both 110 stainless steel balls and 238PuO 2 fuel for the slow milling operation. After which, the fuel must be removed and successfully separated from the ball bearings. This requires removal of both the fuel and the ball bearings from the jar and subsequent reloading of the ball bearings for future operations.


Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
