Ball mill high speed can improve its capacity
Ball Millis mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When dry Ball Mill works, capacity is affected because material flow ability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flow ability of material, so the capacity is increased.
In fact, whether the ball mill, energy-saving ball mill, large-scale ball mill, or the planet ball mill used in college laboratory, cement ball mill in cement industry, their working principle is similar basically. Therefore, the factors affecting their speed have something in common. The working principle of ball mill is driven by revolution and auto-rotating, crushing the samples by the friction force and percussive force in the grinding warehouse. Generally, discharging grain is in direct proportion to the ball mill speed.
In different mineral industry, the effects of ball mill speed are different. For example, in coal mine industry, the speed of the ball mill is directly influencing the movement condition of the ball and coal sheet. It also influences coal grinding process. If the rotary speed is very low, steel ball and coal sheet cannot be taken up, only the lower mill is rolling, the coal output is small. Instead, if the speed reach high, the centrifugal of the ball and coal is greater than the gravity. The ball and coal sheet will rotate together with the drum, losing the role of grinding coal sheet. Rotary ball mill’ speed can make the ball in the rotary drum achieve maximum hoisting height, and then the ball reach the biggest impact, grinding effect is perfect. However, in ball mill practical work, its speed is limited by transmission device speed and external other conditions. The ball mill is impossible to achieve optimal height; it is generally close to each other.

Ball mill should be installed in a solid concrete foundation. Filter out the fine material from the overflow tube. The base of the machine adopts a channel, the machine adopts welded steel.
Rotational speed of ball mill will affect the grinding medium?
When other conditions are the same, the grinding medium in the cylinder body movement depends on the ball mill speed. The status of the medium is different, the grinding effect is also different.
Ball mill speed is too low on the production of energy-saving ball mill effects: low speed, medium to cascading movement, shock effect is smaller, the grinding action mainly for grinding, ball mill capacity is low, suitable for fine grinding;
Ball mill speed is too high on the production capacity of impact: energy-saving ball mill at higher speed, throwing motion mode of medium proportion increases, strong impact, grinding to shock, grinding secondly, in favor of crushed course materials, energy-saving ball mill high production capacity. Ball mill with different filling rate, useful power reaches its maximum value when requested by the speed is not the same.
