Mar 15, 2016 · Ball Mill Crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient. In order to crush with one pass, these mills were made 18 to 22 ft. (5.5 to 6.7 m.) in length. Pebbles were used as a grinding medium and the mills were lined with either silex blocks
Jun 01, 2018 · For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower

The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill. Whether the crushing requirement can be achieved depends on whether the grading of the steel ball is reasonable, mainly including the size of the steel ball, the number of ball diameters, and the ball of various
Feb 20, 2019 · It’s not uncommon for a large mine to have independent planners looking after blasting, primary crusher throughput, secondary and ball mill grinding as well as the concentration plant. A single-minded focus by any of these groups to maximize throughput may come at the expense of other units, and ultimately at the expense of overall throughput
For example, the rotation speed of ceramic ball mill has a direct impact on the stationary condition of the internal grinding media and the effect of grinding operation. When the rotation speed is low, the steel balls acting as the grinding media will only be raised to a low height and then roll down from the top under the effect of their own
