HPGR wear vs conventional mills. Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
