· Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.
· Specific Energy Consumption is the power draw of a mill (kW, usually corrected to the pinion or mill shell) divided by the fresh feed rate (as dry t/h). I use the convention that the symbol E is ...
cost over a limestone system of 1,400,000. 3. The ball mills (one operating and one spare) are 84% smaller for the lime design resulting in 1,800,000 capital savings. 4. Lime based system requires less power consumption for the ID fan and oxidation air blowers. The total power consumption for a lime system compared to a limestone
