The Ball mill drive sets the milling drum into slow rotation and the bed of milling media is thus activated, i.e. the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the …
1.The output of ball mill is much larger than that of mineral mill. Although it is smaller than fine crusher, it is a moderate product. A production line group requires suitable machines. The current production efficiency ball mill is fully capable, and the fast work of the fine crusher causes other supporting machines to fail to keep up. So this is also an important reason for its failure to enter the market in …
Ball mill grinding efficiency is influenced by many factors: ore grindability, feed size, grinding product size, ball mill diameter and length, ball mill working speed, liner type, steel ball loading system, grinding concentration, return sand ratio in closed-circuit grinding and feed rate
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%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged
A high level of control can make all the difference to your mills. Our drive solutions allow infinite adjustment of speed, which lets you adjust to varying loads and helps to prolong the mill lifetime. Using the pressure level in the system as reference, you can automatically adjust the mill speed to achieve optimal production This is achieved without gearboxes or foundations, which saves you
