Methods of Improving Grinding Capacity of Ball Mill

Ball mill is one of the important equipment of mineral processing production line, its working status and efficiency directly affect the production capacity of the concentrator, energy sources and energy consumption and other indicators. As the ball mill feed mine and mill load is difficult to establish accurate mathematical model, the traditional control strategy is difficult to obtain satisfactory control effect, so the usage of fuzzy control can be based on process experience to control feed mine, to realize maximum capacity of the ball mill under the premise of guarantee quality.
In the process of dressing the grinding process between the crushing process and sorting process, the effect of grinding the main bottleneck of the concentrator production capacity in the grinding process, in addition to indirectly affect the quality of the final product. The purpose of the grinding is to make all or most of the monomer separation of the useful ingredients in the ore, and try to avoid grinding phenomenon, and to achieve the sorting operation of the particle size requirements for the selection of effective recovery of useful ingredients in the creation of ore condition. According to foreign data show that a good optimization control algorithm, through the multi-factor adjustment, can improve the grinding capacity of 6% -16%, the following is the zk corp engineers based on experience to sum up ways to improve the processing capacity of ball mill:
1. Change grinding degree of raw ore
In the production, if encounter relatively difficult to wear raw ore or ore required to fine grinding, you can consider the economic and site conditions permitting to take a new treatment process to change the grinding of the ore.
2. Optimize the grinding process
In the actual site production, it is possible to optimize the grinding process for the nature of the raw ore, such as the embedded particle size of the mineral, the dissociation degree of the monomer, the grain size of the gangue mineral. Such as pre-tailing, pre-enrichment, stage grinding, pre-grading and other operations to optimize the grinding system, one hand to reduce the amount of wear, on the other hand the early recycle useful minerals.

3. Improve the classification efficiency
The effect of classification efficiency on grinding efficiency is self-evident. In the actual production, the improvement of the classification efficiency can use two grades to raise.

4. The appropriate increase grading back to the sand
The role of grading back to the sand is not only the return of unqualified coarse particles, but also a role cannot be ignored, even if the mill feed mine thicker, so that the ball in the mill length of the entire axial length can be broken, Machine productivity. But when the return to the sand ratio increased to a certain value, the mill productivity increase is very small, the mill to the amount of ore close to the maximum processing capacity, easy to cause up belly, so the sand should not be too large.
