Size reduction control in cone crushers
Circuit throughput J 4 [t/h] describes the absolute total production: J 4 ∗ = max y r J 4 = max y r q prod, where J 4 ∗ is the maximum achievable circuit throughput. This is a simple KPI for maximizing the circuit throughput without considering the production costs and proportions of different product fractions.
