Ball mill

ball mill

ball mill is the material after broken, and then to smash the key equipment. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metals and glass ceramics and other production industries of all kinds of ores and other grind-able materials can be dry or wet grinding.

Ball mill for grinding various ores and other materials, dry and wet grinding methods are widely used in mineral processing, building materials and chemical industry can be divided into. According to different ways of discharge can be divided into two kinds of lattice type and overflow.Service Online >

Ball mill liners

Domestic Ball mill liner gradually being replaced by the high manganese steel liner, but with the continuous application of alloy steel liner in the ball mill liner, has been gradually replaced by manganese and other linings become the mainstream market.

Improve Ball mill efficiency

Control the speed of ball mill work to improve efficiency

In using a Ball mill when we must do all the preparation, Ball mill speed regulation also requires specialized skills, problem if the modulation speed is not good, it will affect the mill's production, the consequences are very serious.

Ball mill speed directly determines the size of the effect of the cylinder body of the state of motion of grinding media and grinding operations. At low speed, the ball mill was promoted within the height of small ball itself by gravity from the top of the ball bearing rolling down the slide, was spilled off the state, then the ball's impact is small, but highly abrasive ore mainly by grinding stripping and grinding, grinding effect is not high.

When the speed is high, the height of the ball is lifted high. After the ball up to a certain height from the barrel, falling along a parabolic trajectory, in Paola working condition. Point has a greater impact in Paola, mainly due to the impact of the ore is crushed to a maximum grinding efficiency. When the mill speed exceeds a certain limit (high speed), the ball does not fall with the rotating cylinder, in centrifugal operation state. Then the ball just does not shock effect, abrasive grinding effect is very small so stop.

For higher speed requirements are not grinding efficiency is higher, more perfect time to avoid the centrifugal phenomenon, we need to control the rotational speed is relatively low. This requires us to carefully observe a lot during operation, monitor the changes in the ball mill. In fact, these are also just a theory, you need a lot of practice, a lot of summary.
