Selection oof Comminution Circuits for Improved Efficiency

The ideal circuit is easy to operate and maintain, is power efficient and has a low or no steel media consumption. In addition, the size distribution and grinding circuit chemistry may impact on the performance of the downstream circuit (Lane, 1999 and Rantanen, 1996).Sino Grinding | Grinding Media,The size of grinding media plays a key role in overall performance of the grinding circuit. Larger grinding media has a smaller grinding surface area, but offers a heavier weight that’s generally used to break larger ore. Small grinding media has a larger grinding surface area generally chosen to help make smaller ore smaller.Mill (grinding) - Wikipedia,A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes . There are many different types of mills and many types of materials processed in them.
