How to improve the Grinding Efficiency of Ball Mill?
The grinding effect of the ball mill directly affects the grinding efficiency and the output of the ball mill. In addition to considering the size of the ball mill, internal structure of the ball mill, product fineness requirements and other factors, should also consider the characteristics of the grinding material, such as grindability, particle size, etc. The main function of the steel ball in the ball mill is to impact and crush the material, and also play a certain role in grinding. In order to improve the grinding efficiency of the ball mill, the following principles must be followed when determining the grading of the steel ball:
First of all, the steel ball must have enough impact force to make the ball mill steel ball have enough energy to crush the particle material, which is directly related to the maximum ball diameter of the steel ball.
Secondly, the steel ball should have enough impact times on the material, which is related to the filling rate of the steel ball and the average ball diameter. When the loading amount is certain, on the premise of ensuring enough impact force, the diameter of grinding body should be reduced as far as possible, and the number of steel balls should be increased to improve the impact times on the material, so as to improve the crushing efficiency.
Finally, the material has enough residence time in the mill to ensure that the material is fully crushed, which requires that the steel ball should have a certain ability to control the material flow rate.
In addition to the above principle of reasonable grading of steel balls, there are also ways to increase grinding efficiency:
(1) Increase the effective volume.
(2) Increase filling rate and rotation rate.
(3) Change the shape of grinding medium.
Ball mill accessories are ball mill gear, ball mill pinion gear, ball mill hollow shaft, ball mill ring gear, ball mill ring tooth, ball mill steel ball, ball mill compartment plate, ball mill transmission device, ball mill bearing, ball mill end lining and so on.
Luoyang Dahua high-efficiency ball mill adopts rolling bearing substituting for sliding bearing, which can save energy 10-20% compared with sliding bearing. It is widely used in black, non-ferrous metal mining, non-metallic mining, building materials, chemicals, electricity, coal, transportation, light industry and other industrial sectors.
