Effects of percent solids and mill loading on ball wear in

The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of 44µm (325mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp

China Good Performance Small Roll Ball Mill Manufacturers

Description. Good performance small roll ball mill is a grinder for reducing hard materials to powder. A ball mill grinds material by rotating cylinder pots with grinding balls causing the balls to fall back into the pots and onto the materials to be ground. The cylinder pots rotates at a relatively slow speed, allowing the balls to cascade through the mill base, thus grinding or dispersing the materials.
