product) and the average percentage of fines generated from each crusher type. Two heuristics guide most crushing operations: (1) lower reduction ratios reduce fines generation and (2) choke-feeding the crushers produces better shaped aggregate but more fines. Fines that do not meet minimum particle size requirements.
