Ball mill grinding fineness of grinding production cost impact analysis is part of the concentrator high, how effective and reasonable control of the grinding fineness is dressing directly reduce costs, improve important economic factor processing plant. We must first fully understand the factors of grinding fineness. To sum up, the grinding fineness factors are: ore hardness, crushing particle size, the grid mesh sieve, to the ore size, number of balls, ball size ratio, ball mill liner wear, ball mill Pai mine mouth flush size. Understanding all of these factors in the production operation, we want to find one by one to find the best adjustment factor. Ore mineral hardness: different minerals, its hardness is not the same, this factor is fixed with respect to the same ore, but also can not be adjusted. However, in production, under the premise of beneficiation technology requirements can be reasonably ore, the ore as possible uniform size, bulk, powdered ore ratio is reasonable stable. Grading machine spindle lifting height, is also an important factor in returning the amount of sand and grinding fineness of. The normal grading machine spindle production requirements into place. Some workers in the concentrator milling equipment maintenance, as ore grading machine not clean, sink set in a long time, the sludge Shen than real, grading machine spindle at the lower levels, because they do not care, energy saving ball mill price, no The spindle is completely down, resulting in less than normal amount of sand back situation. Broken particle size, grate sieve adjustment is construction related, grader blades wear: worn blades, horizontal energy-saving ball mill, with respect to the return to reduce the amount of sand, causing the grinding fineness thicker, in addition, if the blade wear badly , Beijing energy saving ball mill, classifier will affect life, so promptly check blade for wear at work, classifier overflow weir height, energy saving ball mill manufacturers, affects the size of ore precipitation zone, in production we can grinding fineness requirements appropriate to the classifier overflow weir height adjustment, if the requirements of the grinding fineness thinner, a certain degree of angle iron can be welded at both edges grader with a wooden pull plug method to adjust the level of the classifier overflow weir sometimes after long-term accumulation of sludge, can naturally increase the height of the weir. Yield spiral classifier What factors? Yield how decisions spiral classifier mainly based on speed and width of the tank spiral classifier to decide that it was how the decision? Spiral speed should meet in order to send the settlement with grit. Speed ??grader screw shaft faster the agitation of the slurry, the stronger, the more entrained coarse overflow product. In order to obtain a thicker handle overflow and faster than the major settlement material, the spiral speed can be increased, but not too large, so as not to destroy the grading effect. But for secondary grinding or grinding cycle used in the classifier, the screw speed should try to slow down some. In the spiral classifier generally used in low speed, especially for large spiral classifier. For example, to obtain a crude overflow, 2m diameter screw speed can not exceed 6r / min, generally more than 1m in diameter screw speed should be controlled at 2 ~ 8 r / min. The width of the trough overflow discharge speed has a lot of products, wide trough the overflow discharge speed and, therefore, the greater the likelihood of coarse discharged with the overflow. But on the other hand, the wider the ore trough of the greater size of the settlement, easy settlement. Therefore trough of width on grading effect is not great, but with the processing power is closely related grader. The width of the trough, there is a large processing capability. On the other hand, the processing capacity is small. Therefore, the width of the groove grader should be the size of the mill processing capacity to adapt. Spiral classifier beneficiation process is an important device, which is widely applied to various ore beneficiation operations, improve mineral production is an important device.
