Efficiency Of Stirred Ball Mills Conference Ostigov

Dec 31, 1995 A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill. The grinding laws were tested for fine grinding and Charles law and Rittingers law was found to most closely satisfy the experimental data. The effects of ball size, ball charge mass and media type were investigated.
