This type of limit was also introduced in balance models [15,17] or directly in comminution law such as in the Tanaka model [2], which modifies the Rittinger model by assuming a limit surface [[18], [19], [20]]. In this paper, we present a detailed investigation of the dry grinding of silica sand in an oscillatory ball mill.

Slurry is a mixture of a solid and a liquid. The density of a slurry can be calculated as. ρ m = 100 / [c w / ρ s + [100 c w] / ρ l] (1). where . ρ m = density of slurry (lb/ft 3, kg/m 3). c w = concentration of solids by weight in the slurry (%). ρ s = density of the solids (lb/ft 3, kg/m 3). ρ l = density of liquid without solids (lb/ft 3, kg/m 3)
