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, 1962 Razumov, 1947 Supov, 1962. Therefore, for the biggest grain size, it is necessary to have a definite number of the biggest balls in the charge,
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 ...
In this paper, the milling parameters of high energy ball mill Fritsch Pulverisette 7 like vial geometry, number and size of balls and speed of the mill were modelled and discussed. Simulations through discrete element method DEM provide correlation between the milling parameters. A mathematical model is used to improve and develop this process.
