Ball wear and ball size distributions in tumbling ball

Ball Wear And Ball Size Distributions In Tumbling Ball

Abstract The theory of the calculation of the size distribution of the equilibrium mixture of balls in a ball mill is developed. The differential equation is solved for wear laws of the form wear rate per ball r2 where r is ball radius. 0 gives the Bond wear law and 1 gives the Davis wear law. Methods of determining are illustrated. Experimental data are presented which ...

The working principle of the vibratory grinding mill is based on intense motion of the grinding balls, with both inertia and centrifugal forces. The energy produced using the Sweco mill is higher than that produced by the ball mill, making it more effective in reducing the particles size to 0.5 micron or less.
