A discussion on the measurement of grinding media wear

A material's susceptibility to wear depends on its physical and mechanical properties as well as on environmental factors, ie, the conditions to which the material is exposed In other words, the wear is a function of the tribosystem (), which is made up of four elements: body, counterbody, interfacial element and environmentThe action of each one of these elements can vary, as well as the
