Aa we are konw,controlling the fineness effectively is the crucial fact to reduce the beneficiation cost directly and improve theeconomic effect of the magnetic separation process. Firstly, you should know about the entire effect fact of the grinding fineness. To sum up, the facts that effect the grinding fineness are: hardness of raw ores, crushing particle size,size of the screening hole,amount of the feeding ore, ball mill type, steel ball amount, ball size ratio, ball mill rotational speed, classifier rotational speed,etc.
Raw ore hardness:
The hardness is different for different ores. The fact is fixed for one ore and can never be adjusted. But in the process, at the premise of beneficiation process technology, you can match the ore reasonably to make the size of the ores uniform, and reasonable and stable in the ratio of block shaped ore and ash ore.
Size of the crushing particle and screen hole:
It is crucial for the fact of crushing particle size and adjustment of screen hole. The workers of the ball mill should monitor the crushing system. If the feeding size of the ball mill changed, the worker should reflect to the crushing workshop immediately. The finner for size of the finial crushing size, the better.
Rotational speed of ball mill and classifier:
The rotational speed of ball mill and classifier are fixed when bought, so please check and consult that when buying.
After knowing these facts, we should check one by one when production operation to fine the perfect adjustment fact. Controlling the grinding fineness reasonably can reduce the beneficiation cost directly, so that it can improve the economic effect at the same time.
