Ball mill is the key equipment for crushing the material after it is broken. Ball mill is widely used in cement, Portland products, new building material, refractory material, fertilizer, black and non-ferrous metal ore dressing and glass ceramics production industry, of all kinds of ores and other materials may be grinding of dry or wet grinding. Characteristics of ball mill structure The ball mill consists of the feeding part, the feeding part, the rotating part, the transmission part (reducer, small transmission gear, motor, electric control) and so on. The hollow shaft adopts the steel casting, the lining can be changed, the rotary gear adopts the casting roll tooth processing, the barrel has the wear-resisting lining board,has the good wearability, the machine runs smoothly, the performance is reliable. Dry ball mill and wet grate ball mill can be selected according to material and drainage mode. Wear and loss of ball mill The wear and wear of the ball mill is mainly used for the lining board, the wear of the lining board and the service life of the ball mill are related to the cost and the production effect of the ball mill. So how to identify the merits of the lining board, mainly from three aspects, the casting and smelting technology of lining board of the first see, quenching and tempering treatment of lining board of the second look at whether qualified, finally see lining material, common on the market at present with high chromium cast iron, the liner material low alloy wear resistant cast steel, high manganese steel materials, three kinds of material of the lining board has good wear resistance. Hongxing machine factory welcome you to visit our factory to inspect the ball mill and its lining production process. Working principle of ball mill Material composed of feeding device through the hollow shaft spiral evenly into the mill first warehouse, the warehouse has ladder plate or corrugated plate, built in different specifications of steel ball, cylinder rotate falling after the ball to a certain height, the centrifugal force is generated on the material and grinding effect. After the material is roughed up in the first warehouse, it enters the second warehouse through the single-layer compartment plate, which has a flat lining board, with steel ball inside, and further grinds the material. The powder is discharged through the discharge grate and the grinding work is finished.
