WEBApr 1, 2017 · Abstract. Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute mediumhard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.

WEBApr 1, 2019 · Crushing setting: Efficiency. Ideally, the reduction ratio of a jaw crusher should be 6:1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent.
