HPGR—FAQ - Synopsis

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
