  • An Overview of Lime Slaking and Factors That Affect the

    2021-4-12 · Ball mill slakers are an adaptation of ball mills which originally were designed for wet and dry grinding to lime slaking. Two types of ball mills are used for slaking horizontal and vertical. Ball mill slakers are generally used where the capacity required is too large for other types of slakers.

  • 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 Δ where r is ball radius. Δ = 0 gives the Bond wear law and Δ = 1 gives the Davis wear law. Methods of determining Δ are illustrated. Experimental data are presented which
