efficiency ball mill

The grinding processing efficiency by ball mill, such as mill installed ball, ball filling ratio, ball type, fill number of ball, fill ratio of ball and ball type etc. can affect the ball mill throughput.

Generally speaking, we determine the processing capacity of the mill from the point of. Ball mill ball charge; ball load ball type (several ball); ball mill ball load ratio (ball weight percent); roller mill daily production of complement number of ball, adding kinds (adding several ball), adding the proportion of.

To improve the efficiency of the ball mill should consider the following:

(1) ensure the proper speed of cylinder, the raw material and the grinding body form falling movement.

The slow speed, the centrifugal force is small, friction is small, not with the grinding wall rise, it is impossible to form a throwing motion, on the other hand, excessive speed, the centrifugal force is large, the friction force is large, the grinding body close to the cylinder

Rotating wall body, can not form the parabolic movement, not the parabolic movement, grinding body there is no impact on raw materials, and only grinding effect, reducing efficiency, so the cylinder speed too slow or too fast is not desirable.

(2) choose appropriate liner and grinding body.

The lining has two effects, one is the protection of the barrel body is not worn out, on the other hand to prevent material contact with iron, avoid material pollution. The general rule and choose a wear-resistant lining, ensure durable. meanwhile

Increase the effective volume, in the formula, feeding amount are the same premise should choose high density, high hardness, grinding body size ratio is reasonable, to shorten the grinding time, and reduce the wear rate of the grinding body.

(3) to determine the material, ball, water ratio. Have a significant impact on improving the load of the grinding body on the milling efficiency, less load, material on the touch

Hammer and grinding effect is small, the load is too much, the feeding amount is reduced, the grinding body interaction increases, reducing power and grinding of materials for. When loading a certain amount of each feed grinding body, ball milling is different

Not the same, the feeding amount is too small, it can shorten the milling time, but output is decreased, the feeding amount too much,

The cylinder residual space, reduce the impact effect of the grinding body, the milling efficiency is low. The ratio of material and water should be appropriate, and finally to see the mud, the water cut rate, liquidity and into the water, too little water slurry is too thick,

The material dispersion difference, motion resistance of the grinding body increase, weaken the material crushing effect. On the contrary, too much water, it is necessary to reduce the amount of feeding, and slurry is too thin, grinding body between the direct impact and abrasive opportunities, both the loss of the energy and increase the grinding body wear rate, under normal circumstances, the proportion of material, ball, water for 1:18:6, but total material, ball, and water mixed volume should be is about 90% of the effective volume. In addition, you can also adjust the formula, reduce the types of hard raw material, the maximum diameter of coarse particles in the control, select the appropriate additives to improve the efficiency of ball mill method.
