Get Price01.09.2013· The ball size is one of the critical factors for determining the mill performance of ball mills. It is well known that larger balls are needed for the effective breakage of large-size particles, whereas smaller balls are more effective for the breakage of fine particles. Therefore, it is a common practice in industry to use a mixture of balls rather than balls of a single-size to ensure the
Get Price01.09.2013· For a single size of make-up ball, the mass fractions in the mill within the size ranges are calculated from: (11) m k = d k u 4 − Δ − d k l 4 − Δ d max 4 − Δ − d min 4 − Δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, d max is the largest ball size in the mill, and d min is the smallest ball size in the mill which is still retained. Δ is a constant, which relates

Get PriceA 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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the
