• ## THE OPTIMAL BALL DIAMETER IN A MILL

The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al, 1976; Fuerstenau et al, 1999; Kotake et al, 2004) The basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the grain hardness (Bond, 1962possible to determine the size of mill required based on throughput and therefore the motor power 22 Factors Affecting Size of Product from Ball Mill It is important to fix the point where the charge, as it is carried upward, breaks away from the periphery of the Mill This is called as “break point” or “angle of break” because it isCorrelations for the Grindability of the Ball Mill As a• A useful guideline for makeup ball size for a new circuit was provided by Bond (1958) B = (F80/K)05 x [(WI x SG)/(Cs x D05)]1/3 (3) In the historical British units: B Recommended makeup ball size, inches F80 Circuit feed 80 percent passing size, microns K A constant, 350 for wet overflow mills, etcBall mill media optimization Metcom Tech

• ## Ball mill Wikipedia

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 A ball millBesides particle size reduction, ball mills are also widely used for mixing, An important characteristic of an industrial ball mill is its production capacity which is measured in tons of production per hour The production capacity depends 53 on mill dimensions, the type of the mill (overflow or grate discharge), the speed of rotation, the mill loading, the final product size requiredGrinding in Ball Mills: Modeling and Process ControlBall mill size and production throughput calculate ball mill throughput in optimum choice of the makeup ball sizes for maximum throughput the ball size is one of the limestone kaolin production ball mill size and production throughput crushing equipment is designed to achieve maximum productivity and high reduction ratio from large primaryBall Mill Throughput Calculator | Application Of
