A Review on the Effect of Impact Toughness and Fracture ...

 · Sare et al. (Ref 82) studied the impactabrasion wear resistance of a set of white cast irons with different harnesses using an impact crusher test. From the results summarized in Fig. 8, it can be seen that the weight loss does not correlate satisfactorily ( R 2 values below 25% for a polynomial grade 2) with either bulk hardness or superficial hardness.

Lime Production: Industry Profile

whereas impact crushers rely on intense, repeated blows. Compression crushers are used mainly for larger stones, impact crushers for smaller sizes. In some plants, stones undergo secondary crushing as well. The crushed stone is screened to provide the desired stone size and then conveyed to storage in conical stockpiles (Gutschick, 1994).
