The process is characterized by: a smaller number grader, low investment, easy to produce, adjust the simple; there is no intermediate between sections, multi-series grinding machine can be placed on the same level, so that the configuration of the device It is relatively simple, not because some mine or mill stoppage affecting grader work another mill ore segment, thus stoppage loss is small; the series of larger devices can be installed. One estimate disadvantage grinding process: the grinding machine feed size range is very wide, reasonable ball hard, low grinding efficiency; some grinding process in the general classification overflow fineness Oh -200 mesh about 60%, difficult to obtain finer end product. According to the aforementioned characteristics, all requirements of the final ground product particle size less than 0.2 ~ 0.15mm (ie, -200 mesh accounted for 60% to 72%), generally should adopt some grinding process, in a small concentrator, oh simplify grinding Process and device configuration, when the grinding fineness of -200 mesh point when 80%, may also be used for some grinding process. Grinding process two outstanding advantages: You can coarse and fine grinding of ore at different grinding segments, grinding and ore two segments can be using different grinding conditions (ie, the larger roughing Fashion Ball and using high speed, with a smaller ball and a lower speed when finely ground), will help improve grinding efficiency; Another big advantage is suitable for stage separation, that is, treatment is not When evenly disseminated ores and ore containing high density in grinding cycle using sorting operation, can in a timely manner would have been monomer dissociation of mineral sorting out and prevent excessive crushing phenomenon, will help improve the quality indicators beneficiation, while reducing heavy metal mineral sand back in the hierarchical aggregation, can improve the classification efficiency classifier. Because some, in the medium-sized processing plant, when it is desired grinding fineness of less than 0.15mm, two-stage grinding better.
