Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force. In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear and compression force

The wet ball mill pulping system process of limestone and material balance has been analysised in th wet ball mill. On the basis of this,optimizing adjustment has been done on one wet ball mill. After the adjustment,limestone grinding amount per unit time rises from 7 t /h to 11 t /h,energy consumption per hour fall by 98( kWh),which has significant energy-saving effect.

Thus, 30% of V B,total are taken by the milling balls. Increase of the initial batch sizes changes Φ GS significantly. However, within the investigated parameter range no negative influence on the yield was observed. Up to 50% of V B,total can be taken over by the substrates in addition to 30% for the total milling ball volume. Scale-up factors of 15 and 11 were realized considering the amount of substrates

2017-2-16 PARTICLE TECHNOLOGY LAB REPORT 33 Procedure of Ball Mill Measure the inside diameter of the ball mill. Measure the size of the ball with the help of venire calipers. Fill the ball mill to about half of its volume with balls of the same diameter. Feed t ball mill with 250 g mass of sugar of homogenous size (obtained by screening) and note the particle diameter. Before turn on the mill, set speed regulators to maximum. Measure the speed of rotation of the ball mill
