Bauxite Grinding Sag Mill. Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long For this reason rod mills are rarely selected in the present day environment of large AGSAG mills and large ball mills However it is necessary to discuss their operation because a Rod mill product has a similar slope to AGSAG mills .

An alkaline slurry from a bauxite grinding mill was scheduled to be classified using a spiral classifier at the underflow rate of 1100 t/day. The width of the classifier flight was m and the outside diameter of the spiral flights was m. Estimate the pitch of the spirals if the spiral speed is 5 rev/min and the bulk density of the underflow solids is 2000 kg/m 3. A Krebs D6B (6 ...

· SAG mills grinding media includes some large and hard rocks, filled rate of 9% – 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills. How does a sag mill work? The working principle of the selfgrinding machine is basically the same as .
