2017年2月13日· CERAMIC LINED BALL MILL Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′ High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volumeFor a geardriven ball mill, use the following: Total Ball Mill Motor Power = (Ebm × tonnes/hour) ÷ 0985 ÷ 094 ( 10 ) The largest motor sizes currently on the market with pinion and gear drives are in the 10 MW range (these would be a twinmotor arrangement with one motor on either side of the mill)(PDF) ball mill | Sheetanshu Pandey Academiaedu
One way to calculate a ball mill's grinding efficiency is to divide its total static horsepower (TSH) by its total theoretical tonnage (TPT) This number can then be used to compare different types of mills A TSH of 10 hp/tonne is considered to be very efficient, while a TSH of 20 hp/tonne is considered to be moderately efficientOne can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill A f80 = 6 mm would need a ball size of 75 mm An empirical model from "Emerging Trends in Mineral Processing", 2005, isFeed Size VS Ball Size Grinding & Classification Circuits

Is there any other sideeffects associated with feeding a ball mill with 16 kWh/tonne feed which is coarser (closed P80 of 134 mm vs open P80 of 154 mm ie2 mm coarser)? One assumption in all this is that a ball mill is available which has lots of grinding length,
