Closed with a flip-flow screen, the HPGR reduces the feed size from −12 to −1 mm, and the tower mill circuit produces a flotation feed with a fineness of 85 % passing 0.074 mm. This comminution circuit has HPGR for partial coarse grinding and uses tower mill to replace the energy-inefficient ball mill for primary grinding.

Stone burr mills are the most traditional and produce an exceptionally fine quality of flour. Mills use a pair of grinding stones made from a durable material, such as granite or a similar material, to slowly grind the grains into flour. This method ensures a consistent texture and preserves the nutritional value of the grain.
