The reduction ratio of a horizontal impact crusher is much higher than that of a jaw or cone crusher. The Trio® APP series is the larger of the two crushers and is used for primary stage crushing of larger feed sizes. It is a very versatile machine, but does not produce as fine a product as the Trio® APS series.

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 medium-hard rock or sticky materials. An unusual tough particle or unbreakable object may effect substantial dynamic forces in a DRC.
