Ball Mill Simulation In Wet Grinding Using A Tumbling Mill

jun 25, 2004 visualization of actual ball motion in wet millingthe mill used in this work was a tumbling ball mill made of stainless steel having 81-mm inner diameter and 110-mm length. monosize steel balls of 10-mm diameter were used as grinding media. In order to visualize the motion of balls, one side of the mill lid was made of transparent acrylic acid ball charge loading impact on specific power asocem. In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter ratio, individual compartment degree with respect to specific power consumption and product research concludes that lowering the ball mill filling percentage negativelyball mill batch process the mill dimensions, are 0.204 0.158 and it after time the mill product is wet screened at a predetermined screen size. from the weight difference of the over size before and after grind- ing one calculates the grinding rate. the over size is then dried returned to the mill
