grinding media wear

A discussion on the measurement of grinding media wear

wear mechanisms that take place during the grinding process, as well as to consider the details of such process like the inhomogeneous feed and the interaction between mineral slurry and grinding media. Wet grinding can also add a corrosive component to total wear mechanism, and then wear rates are expected to rise from synergies between

CALCULATION OF WEAR RATE

where F is the normal load, s the sliding distance, V i the wear volume and k i the specific wear rate coefficient. Index i identifies the surface considered. The k-value is given in m 3 /Nm or m 2 /N, sometimes in mm 3 /Nm. From design view the wear displacement h is more convenient than V.
