Roll Crushers Pressure

Roll crusher working principle | Henan Deya Machinery Co

Since there is no provision for the swelling of broken ore in the crushing chamber, roll crushers must be “starvation fed” if they are to be prevented from choking. Although the floating roll should only yield to an uncrushable body, choked crushing causes so much pressure that the springs are continually “on the work” during crushing, and some oversize escapes.

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
