Influence of particle size on wear rate in compressive crushing
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. Not only mean particle size, but also size distribution width also has an influence on wear rate.
