5 Construction, Working and Maintenance of Crushers for Crushing Bulk Materials In a nonreversible hammer mill with screen bars, shown in above figure, material is broken first by impact between hammers and breaker plates and then by .
1. The author has derived new equations of crushing kinetics, expressing the variation of the sieve residue surface, relative to that of the grains of the control size, with the crushing time. 2. The use of these equations enables one to calculate the increase in mill output according to the degree of decrease in the initial ore size, its hardness, and the crushing size.

milling followed by ball milling), only the P80 of the product of the final milling stage is required. In addition to the above data, a representativesample of the primary crusher product is required for subsequent laboratory hardness characterization. From the Laboratory The Morrell method uses hardness parameters obtained
assumes that a crusher would provide this energy. However, in this situation the ball mill has to supply this energy and it has a different (higher) work index than the crusher (ie the ball mill is less energy efficient than a crusher and has to input more energy to do the same amount of size reduction). Hence from equation 7, to crush to the ...
