calculation of ball mill charge volume - Popular Education. The optimal ball diameter in a mill of the equation for determining: the optimal ball diameter depending on the grain, then the determination of the optimal ball charge model in a mill 2, grinding samples was equal to the volume of the interspaces of balls .
Sep 01, 2013· gives the optimum composition of 40% 50.8 mm ball and 60% 25.4 mm balls for a 1 m diameter mill, and 27% 50.8 mm and 73% 25.4 mm for a 2 m diameter mill when grinding from a 90% passing 9.5 mm feed to an 80% passing 150 μm product. The portion of 50.8 mm balls decreases as the feed size or the product size decreases.
The optimal ball diameter in a mill. grinding quartz and copper ore in a laboratory ball mill, there has been defined efficiency, as well as its confirmation by the results of the experimental cases, the specific power consumption increases and the grinding capacity decreases.get price
Effect of ball diameter has been studied on the limestone and clinker samples under batch grinding conditions based on a kinetic model. Firstly, eight different mono-size fractions between 1.7 mm and 0.106 mm formed by a √2 sieve series have been prepared.

OPTIMAL BALL DIAMETER IN A MILL; Grinding_Operations_Design; I reproduced or doctored two tables and graph from an article dating back to 1948 I found interesting for its easy to use graphs.. In his paper "The Preferred Size of Balls for Ball Mills."Mr. V. A. Olovskiy concludes:
then the determination of the optimal ball charge model in a mill. 2. Theoretical background Each grain size corresponds to a definite optimal ball size. The diameter of a ball is determined by the condition that, at the moment of breaking the grain, it has energy E, which is equal to energy E 0 necessary for grain comminution: E E 0. (2)
