"Full grind" also known as "full grind" or "boring mill," is a common procedure in a wet ball mill
operation is not a normal phenomenon. "Full grind" sign: degree by the clear light grinding sound turned low, grinding tail deposit size reduction in the import and export dumping dry grinding pressure increases; the extent of Lantus grinding sound disappears, the main motor current drops about 70 percent of normal, grinding tail greatly reduced the quantity; severe degree of special grinding returning materials, not feed mill tail, pulling pump gas exports are not even a little. If you open the door to check mill can be found: 1, board sticky material is very thick (some about 50mm), on a ball wrapped in a very thick material layer; 2, diaphragms grate seam serious congestion; 3, the warehouse about 90% of the available space is occupied by the grinding media and materials; "full grind", while also accompanied by a thickening of the grinding fineness and chemical products very significant change phenomenon. Chemical extreme changes in the law: "full grind" of the early, difficult to grind ingredients ingredient significantly reduced, "full grind" the gradual elimination of, the content of the hard grind ingredients also significantly above normal.
"Full grinding" is a tube mill feed, the quantity loss of balance, caused by excessive wear in a short memory quantity, the reasons are: 1, excessive volume of feed grinding grinding capacity can not meet.
2, the granularity of the material into the mill grindability bigger or worse, there is no time to reduce the volume of feed.
3, into the grinding material moisture is too high, and poor ventilation, water vapor and wind can not fine material generated during grinding out outside the mill in time, causing the material due to high humidity and surface adhered to the ball and lining, increasing large buffer to reduce the grinding efficiency; and wet material also blocked diaphragms and discharge grate plate gap,...
