Ball mill liner is an effective means to improve the mill fineness of a long, grinding is dressing up in the production process cost effective use of grinding fineness is dressing directly reduce costs, improve important factor beneficiation plant messages. Ore mineral hardness: different minerals, their hardness is not the same, this is a factor with respect to the same fixed ore, but also can not be adjusted. However, in production, under the premise of the technical requirements of the beneficiation process can be carried out with reasonable ore, the ore as possible uniform size, bulk, powdered ore reasonable ratio stable. In addition to the belt in a ball mill at the mine, due to prolonged wear belts may leak mine, under most circumstances is leave out the powder ore, this part of the mine must be timely supplemented to drain as much as possible in a ball mill, if prolonged stacking, centralized add, will result in uneven milling ore, causing production instability. In particular, it is difficult to beneficiation, mineral powder and often block mineral properties vary. As a highly efficient ball mill grinding equipment, its technical features is a stand-alone production capacity, low energy consumption per unit of product, a narrow particle size distribution, good purity, good liquidity, as a vertical mill ultrafine grinding equipment, has been widely used in the production and processing of foreign white non-metallic mineral industry, the current size of the non-metallic minerals also tend to use the equipment and technology process to produce TSP, barite, limestone and other non-metallic mineral products, with the ultra-fine grading equipment and deep-processing with equipment to meet product fine production. As a ball mill workers to operate, relatively fixed without frequent adjustment factors are: ore ore hardness, crushing particle size, lattice screen sieve, a ball mill models, quality of steel balls, steel balls added amount, the proportion of ball size, ball speed, classifier speed grading impeller spacing, grading machine spindle lifting height, grading blade wear, ball mill classifier overflow weir height, at the opening level classifier, the opening size of the next grading machine, grading machine opening height, size of the opening on the grader. This part of the early development of the factors for the design and technology.
