Ball Mill Parameter Selection & Calculation Power
Aug 30, 2019· 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of

Ball Mill an overview ScienceDirect Topics
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel.

Jun 01, 2018· Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used. If an objective function was to maximize the production of fines e.g. in the cement industry, the A.R shows that use of smaller ball sizes would give superior results.

However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ball mill circuit feed size

which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c.
