How to improve ball mill equipment grinding fineness is an important part of the entire beneficiation operations, grinding operations cost concentrator higher, how to effectively control the grinding fineness directly reduce the processing cost, an important factor to improve the economic efficiency of the processing plant. Ball mill equipment grinding fineness, is one of many factors that affect the beneficiation indicators, the size of the grinding fineness direct impact on the level of concentrate grade and recoveries. Therefore, the technical operation of the ball mill is extremely important.
We must first fully understand the the grinding fineness impact factors. To sum up, the factors affecting the ball mill equipment grinding fineness: ore hardness, crushing particle size, grizzly sieve size to the amount of ore ball mill equipment models, the number of balls, steel ball size ratio, ball mill liner wear ball mill equipment speed, the rotational speed of the grader, grading machine spindle lift height, grader blades wear level classifier overflow weir grader next opening level, the size of the opening grader grader opening level. grader on the size of the opening, at the sand back to the flow size, ball mill equipment the feedwater size, ball mill equipment row at the entrance to the mine flush size. Understanding of all these factors, the production operation one by one to find it, find the best adjustment factors.
Different ore, its hardness is not the same, and this factor is relative to the same ore is fixed, and can not be adjusted. But in production, under the premise of the technical requirements of the beneficiation process can be reasonable with mine, as much as possible so that the ratio of ore uniform size, massive, powdery ore reasonably smooth.
Addition to the mine at the ball mill equipment belt, the belt may leak due to prolonged wear mine, leave out most of the case of iron ore fines, this part of the leaking mine must be as timely fill added to the ball mill equipment, if prolonged stacked the centralized Add to the mine caused by ball milling uneven, causing the production of unstable Especially difficult dressing, often different powder mineral block mineral nature.
