Rod Grinding Process

Coarse particles are held by the rods in the grinding machine for a longer time and thus are subjected to more grinding action. The rod mill process has a great selective grinding effect. The particle size of the grinding product is uniform, and the degree of overcrushing of the ore is light, so the rod mill can form a single-stage rod …


Grinding Balls & Rods

The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods.

Rod Mill Design & Power Draw

The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
