Roll Crushers - ScienceDirect

The feed to roll crushers is usually dry. Moisture tends to clog the crusher and could result in the formation of hard crust, which impairs operation. Hence, dry crushing is preferred. Sometimes, water is added between the rolls, which help to prevent formation of the crust and also to remove the hard cake that tends to form on the roll surface.

The pressure profile across the roll displays a tapering off of pressure toward the roll edges, leading to impaired comminution performance. The ‘edge’ proportion is a function of the operating gap (edge = gap x ~1.2), which is in turn a function of the roll diameter (gap = 2–2.5% of diameter), so a high aspect ratio design has a greater edge
