# Ball wear in ball mill

Feb 01, 1993 Ball mill wear occurs as a result of the violent interactions within the ball charge. In the present article, a mathematical description of wear has been added to a ball charge motion model. Wear is associated with the comminution mechanisms found in the ball charge profile. It is assumed that ball mill wear occurs in each of three comminution

• Mathematical model of ball wear in grinding mills I. Zero

Mar 01, 1986 Since the ball wear in a tumbling mill is a very slow process, the usual industrial practice of charging balls once a day or once a shift may be considered continuous in time with regard to the long time-intervals involved in the process. On the other hand, a limited number of ball size classes are charged to the mill and approximately one size

Aug 23, 2021 Aug 23, 2021 3.There is a large amount of ball wear in the ball mill In the grinding operation, the consumption of the steel ball accounts for more than 10 times of the liner of the ball mill. Here are the reasons for it: Quality of steel balls. The quality of the steel ball has a greater relation to ball consumption. The wear resistance of the surface

• how to estimate the wear rate for Ball mill - Page 1 of 10

Dec 08, 2009 Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated

• Ball mill liner excessive wear reasons

Oct 22, 2021 Oct 22, 2021 During the grinding process, the ball mill steel balls and the material fall in a throwing motion in the cylinder. At this time, the ball mill liner and the steel balls, and the material will collide with each other. In continuous operation, the ball mill liner and steel balls will experience serious wear

• Effects of percent solids and mill loading on ball wear in

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44- m (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp

• Optimization of mill performance by using

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
