With an increase in ball milling time, DAV decreases from 60.1 to 35.5 µ m. When the ball milling time is 50 min, DAV reaches the minimum value of 35.5 µ m, a 41% decrease compared with the value before ball milling. When the ball milling time exceeds 50 min, DAV fluctuates with a variation of ∼3% (Figure 9 (d) ).Comparative study on the characteristics of ballmilled ,Highenergy mill (HEM) has a wide application in material preparation, activation and synthesis. In the present study, fly ash was selected to be milled by HEM under the speed of 700 rpm and the balltopowder ratio of 10:1 by weight, but varied periods of milling time.

For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ‘ slurry ’.BALL MILL MAINTENANCE The Cement Institute,Learning Path. Module 1: Welcome and Plant Safety.
