Calculate and Select Ball Mill Ball Size for Optimum Grinding

Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm.

Ball Mill an overview | ScienceDirect Topics

where d 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.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.

How Ball Mill Ore Feed Size Affects Tonnage Capacity 911 Metallurgist

As a result, the mill output will increase with this reduced size to approximately 77,000 tons per day. The gain in production compared to the 13,000 micrometer feed will be: (78,000 65,000)/65,000 x 100 = 20%. The theoretical gain will actually be greater because the graph in Fig. (21) is constructed according to the GatesGaudinSchuhmann ...

Ball mill Wikipedia

A section cutthrough of ball mills. A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
