Wear rate of the grinding balls • Power requirements of the mill • Income from scrap sales E = 10 X Wi (1/ P80 - 1/ F80 ) E = 10 X Wi (1/√P80 - 1/√F80 ) Wear rate of the balls To calculate the wear rate of the balls, the team first calculated the mill's filling of the grinding media. With this, the number of balls

(PDF) MODELING THE SPECIFIC GRINDING ENERGY AND BALL

The proposed model correlates the specific grinding energy, the clinker work index and the specific surface (Blaine) of a cement produced through fine-grinding in ball mills.

Process engineering: Particle size reduction techniques

15-02-2005Wet grinding often takes place in ball, pebble or rod mills. The efficiency of wet grinding can be higher than that for dry grinding, but wear of equipment is also higher [2]. Most size-reduction equipment is subject to heavy wear and therefore parts, such as casing liners, hammers and jaws, are designed for relatively easy replacement.

MILLING CONTROL OPTIMISATION

ore treated was very difficult to mill. In the first two days, the mill experienced numerous power dips (overloads), and on at least seven occasions the feed to the mill had to be completely stopped to grind the mill out. Also, the mill load varied in the range of 125 to 165 tons. These disturbances propagated throughout the milling circuit and
