    The Wear Speeds in secondary grinding are found to be 25 – 40% lower than those seen in primary milling when grinding the same, but finer, ore. This comparison shows that the reduction of the i mpact component of wear due to the smaller media size offsets the increase in an abrasive wear expected when grinding to finer product sizes
