Volume 2, Issue 11, May 2013 Studies on Batch Grinding

2014-1-14  The effect of time of grinding in a ball mill has been studied covering a range of 3 minutes to 15 minutes. 50 g of feed of the size 0.475, 0.675 and 1.0 cm were feed to the mill and the mill was run at the speed of 66 rpm. The number of balls of one inch size kept as constant at 100. The specific surface area per eachrun is calculated and the results are shown in figures Fig 1, 2 and 3 shows the variation of specific surface with time, which shows that the specific surface produced, continues to increase with time. Fig 4 shows the variation of Specific Surface with Energy consumption which reveals that power consumption increases with specific surface. Fig 5 shows the variation of Rate Constant with Time. The Rate Constant is decreasing with increasing time. The reasons for increase in the initial periods are due the fact that coarse particles are being introduced in to the mill
