Note: The poor grinding effect of the ball mill and the large discharge particle size are mainly due to these five major reasons
The ball mill is the key equipment for crushing the material after being crushed. The ball mill machine is widely used in the production industries of cement, silicate products, new building materials, refractory materials, and black and non-ferrous metal beneficiation. It is suitable for various ores and other grindability. The material is ground in dry or wet mode. The ball mill equipment is suitable for grinding various ores and other materials, and is an indispensable grinding equipment in the mining industry. However, in the course of use, we sometimes have coarse discharge, large particle size, unevenness, etc, which affect the quality and price of the finished product. So what are the reasons for this problem? The following is a detailed introduction by the editor and the solution for you.
1. The number of grinding bodies is too small
If the loading capacity of the grinding body in the coarse grinding chamber of the ball mill device is too small, the steel balls are too small, or the filling rate of the grinding body in the fine grinding chamber is lower than that in the coarse grinding chamber, this situation will result in insufficient grinding of the material and the grinding effect. We should increase the loading capacity of the grinding body, adjust the gradation of the grinding body, increase the ratio of the large balls, or appropriately increase the filling rate of the grinding body in the fine grinding chamber.
2. Too much feed
When the feeding amount of the ball mill machinery is too large or the feeding amount in a short time is too large, it may cause insufficient grinding material of the grinding body, and it is easy to have low grinding efficiency and uneven discharge particle size. We should feed evenly and prevent Too much feed at one time.
3. The grate gap of the partition board is too large
When the gap between the grate seams of the ball mill facility compartment plate is too large, the materials that have not reached the required particle size will be screened out, resulting in a large output particle size. Therefore, electric welding can be used to weld the steel bar to the excessively large gap.
4. The compartment board is damaged or dropped
When the compartment plate of the ball mill appliance is damaged or dropped, it will cause the grinding bodies in the barrel of the ball mill to flee, and the material cannot be well ground. The compartment plate should be replaced or installed, and the mixed grinding bodies should be sorted.
5. Too little moisture in the slurry
When the ball mill machine is running and the water content of the grinding slurry is too little, it will cause the slurry to stick to the grinding body or the liner, forming a "cushion layer", which will affect the crushing ability of the ball mill. The slurry moisture should be increased to an appropriate level.
The above are the common reasons and solutions for the poor grinding effect of the ball mill equipment and the uneven discharge particle size. For some serious problems, you need to consult a professional technical team. The technical team of Nile Machinery has rich experience and practical ability. You can ask us any questions you have, and we will answer them in detail.
