parameters affecting the process of grinding in a ball mill which illustrate the effect of these parameters on the troughput of the mill Kelly and Spottis wood 10 showed that there is a definite relationship between troughput of the mill and the speed which the mill rotates
The aim of this project was to determine the effect of the ball diameter on the operating parameters of the mill which included the energy efficiency the power requirement mill load critical speed as well as the size reduction of the mill charge It was thus required that these mentioned operating parameters be optimized by experimentally
Jun 27 2019 Planetary ball mill is a powerful machine used to reduce the particle size to nanosize depending on centrifugal accelerating force rather than gravitational accelerating force which makes the process more efficient and accomplished in a short time 4 Several parameters related to the planetary ball mill can affect the resultant particles
Dec 18 2013 The smallest ball size typically charged into ball mills and tower mills is inch 125 mm although media diameters as small as 6 mm have been used industrially in Vertimills In a laboratory study by Nesset et al 7 a GIS mill charged with 5mm steel shot and with other operating conditions similarly optimized achieved high energy
