Jul 01 2016nbsp018332the first attempts to develop tests for the assessment of wear of grinding balls in grinding mills date from the 1940s in 1942 the idea of assessing the wear by marking some of the balls from the mill load was raised carrying out the test in a batch ceramic mill
The use of ball mills in cement grinding is due to several factors among which are relatively simple design and high processing rate however these machines have certain limitations as well it is known that only 2 to 20 of the energy is consumed by the grinding proper while the rest is expanded on overcoming friction on vibrations and is
History of ball mill productivity sooper articles aug 16 2010183 ball mill energy consumption in the course of work accounted for the majority of the whole process of cement production including power consumption integrated power consumption of cement accounts for about60 70 so how big the energy consumption of quotdownsizingquot is a cement technology workers unremitting goal
Significant variation of balls filling degree 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

Shape balls beads and satellites satisfy the bulk of our customers requirements but we also source highly specialized shapes like ballcones and diagonals diameter depending on the material ranging from 005 mm to 2 mm for small media mills up to 18 to 1 for traditional attritors and up to 189 to 2 for ball mills
I think in ball mills you can use steel balls which are very resistant to wear rates but in sag mills its tricky as the accumulation of small steel balls due to low wear rate in the mill will affect so much your power draw meaning that your power draw will be high whilst grinding efficiency is reduced as in sag mills you need larger steel balls this will cause a reduction in throughput
One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill which is determined by the speed of consumption and rate of
