Coal Roll Mill Crusher

The roll speed must be sufficient to prevent stalling, but not so fast that the coal is violently thrown out of the mill. Roll crushers most commonly have either one or two rolls, as shown in Fig. 9.3 Meyers, 1981 Jeffrey, 2011 McLanahan, 2011 Stedman, 2011, although some may use three or even four rolls in a two-stage crushing system.
