How to Improve the Ball Filling Rate of Ball Mill?


Ball mill is the key equipment for materials to be smashed after crushing, which is widely used in cement, silicate products, new construction materials, refractory, chemical fertilizer, black and non-ferrous metals, glass chinaware and other production industries. It can conduct dry or wet grinding for many kinds of ores and other materials which can be grinded.

In order to remain the filling amount, type and ratio of balls unchanged. In the daily production of ball mill, there should be a reasonable adding of balls, so that the ball type and ball loading ratio can reach balance. This requires the reasonable filling steps for the equilibrium ball. The experimental data shows, the mill speed and ball loading rate determines the motion state of mill medium, which will seriously affect the grinding action. When the ball filling rate is 30-50%, with the speed increase, the ball will be cascaded into dropping type, and the productivity will increase gradually. When the speed ratio is the critical speed of the 80-85%, the ball filling rate should be 40-45%.

High speed grinding and 100-120% as the critical rotation speed rate, its ball loading rate is about 35%. Low grinding efficiency with low ball filling rate; if there are too many balls, the inner layer will be interfered in the operation, which has destroyed the normal circulation of the balls. Lattice type ball mill has ball filling rate of 40-45%; overflow type ball mill is35-40%.
