Nov 18 2008 basic principle ball mill is generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns to achieve a reasonable efficiency with ball mills they must be operated in a closed system there is a specific operating speed for most efficient grinding
Ball mills are generally used to grind material 14 inch and finer down to the particle size of 20 to 75 microns to achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced various classifiers such as screens spiral
Slice mills are identical to the ball mills and ceramic lined mills in diameter and design the only difference is that they are as little as 12 in length since mill diameter dictates performance and mill length only affects capacity slice mills are used to develop or test formulations with little concern for
