A test apparatus was developed to replicate the squeezing wear that is present in many rock crushers. Silica sand of different size classes between 0.725 and 2.03 mm was used. The crushing load was varied. The results show a strong relationship between particle size and wear rate. The wear rate increases as particle size increases.
