range of sizes for ball mills

What particle size range does ball mill grinding

2016-12-22  Ball mill grinding is one method of crushing ore to an appropriate size fraction. Specifically, ore is put into a large receptacle (a drum) and then it rotates slowly around.

where db.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3 ); D is inner diameter of the mill body (m). Generally, a maximum allowed ball size is situated in the range from D /18 to D /24.

Optimum choice of the make-up ball sizes for

2013-9-1  It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters. In all cases, binary mixtures of two ball sizes (50.8 mm and 25.4 mm) performed better than a mixture of the three ball sizes. An equation therefore could be developed for calculating the optimum composition of the make-up balls as a

Mill Speed - an overview ScienceDirect Topics

Tumbling media mills are quite effective for grinding to sizes in the 10–50 μm range, but often require inordinately long grinding times for size reduction into the micron range. (b) Centrifugal mills. Centrifugal mills are, for the most part, a special case of tumbling-media mills, the difference being the addition of a centrifugal component to increase the effective gravitational force.
