AAC production Wet ball mill Masa Group
Sand processing by means of a wet ball mill has proven to be an economically advantageous solution for the manufacture of aerated concrete. Masa attach great importance to an efficient plant layout therefore, we consider important raw material parameters, such as the particle size distribution curve of the sand and the specific size of Ball Mill Dry and wet ball mills have the same basic components, but there are some structural differences: 3 Discharging part Discharging port: Dry ball mill: The ball mill needs to be equipped with an air induction device, a dust exhaust pipe and a dust collector. The structure is more complicated, and the discharge port is straight.BALL MILL FOR ALL YOUR NEEDS

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). A pilot-scale Loesche VRM was used to determine the power required to grind 100 t/h of the same limestone as used at Kusile (work index of 12 kWh/t) with a top size of 19 mm to a 85% and 95% passing 45 µm product. A significant power saving of 39.2% was observed for the dry VRM compared to the wet ball mill (37.7% for the circuit).A Technical and Economic Comparison of Ball Mill Limestone
