module 5: functional perfomance of ball milling

the overall efficiency of the ball mill circuit is therefore comprised of two efficiencies: that of the 'ball mill grinding environment' and that of the 'classification system'.

how to measure grinding efficiency

the power per tonne for rod milling is determined from the rod mill feed rate and the power per tonne for ball milling is determined from the ball mill feed rate. note the efficiency factor of 1.22 lines up with the 1.2 factor recommended for selecting rod mills for rod milling circuit when feed is produced with closed circuit crushing.

five reasons for low grinding efficiency of ball mill cement production

the grinding efficiency of ball mill is influenced by many factors, mainly including:movement form, rotation rate, addition and size of steel ball, material level and use of grinding aid. these factors affect the efficiency of the ball mill to some extent. 1. movement form of steel ball in cylinder

mill grinding - wikipedia

rod mills are less common than ball mills for grinding minerals. the rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. however, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. autogenous mill
