What Type of Crusher Is Best for Primary Crushing? McLanahan

Primary Roll Crushers are available in several designs: Single Roll; Double Roll; Triple Roll; Quad Roll; Roll Crushers are compression-type machines, so output gradation is controlled mainly through the gap setting between the rolls. A wider setting results in a coarser product. A wider setting also provides greater throughput.

Crusher Product Gradation Charts

Crusher manufacturers publish grid charts, particle size cumulative distribution curves, and/or product size distribution tables to help predict the gradation of the crusher product. These charts, curves, and tables give the percentages passing or retained on standard size screens for each given setting of the crusher.
