HPGRs are one of the most effective comminuting devices in mineral processing circuits nowadays. Roller crushers are not widely applied in aggregate comminuting circuits, but through the development of the high pressure grinding technology, the application of roller crushers might be more popular. The roller crusher efficiency was investigated in two variants of the technological circuits.
