Ball mill method to extend the service life of the material to be broken, and then to smash the key equipment. It is widely used in mineral processing, building materials and chemical industries. In the operation, due to various factors, it will wear machine mill, in order to improve equipment productivity dry ball mill, it is necessary to improve their life. What, then, to extend the service life of the ball mill method is it? We analyze the following two points. The need for regular maintenance and repair 1, in routine maintenance, to determine fasteners use, regularly check the fasteners are loose and wear, and wear loose if it is necessary and timely for tightening and loosening replacement. 2, all lubricant release all equipment should be put into operation in a month, and then thoroughly cleaned, replaced with new oil. 3, liner bolts prone newly installed loose bolt in use for some time, will need to be checked regularly basis. 4, regular cleaning of equipment, keep the device clean, reduce dust on the ball damage. Correct use 1, requires a uniform feeding, to prevent a ball mill no material or material damage to the device attitude. 2. Strengthen the ball mill ventilation, to lower the temperature, thereby reducing the liner wear at high temperatures, increase equipment life. 3, the use of closed-circuit grinding, because the pellet mill closed within ratio, so the liner wear rate will correspondingly decrease. 4, using the initiative gear set overload protection. By this means, it is possible to predict and coordination, slow replacement of the drive gear reducer clutch operation. This can effectively protect the ball mill gear unit. Various mill in production, how to choose hair ball in twenty-three broken ranks in the materials in the crushing process, is generally used to smash the key equipment broken after being crude. Mill in cement production, building materials, refractories and special ceramic glass and other industries are widely used, according to the abrasive nature can be divided into wet and dry grinding. According to the different ways of discharge can be divided into lattice-type ball mill, overflow crusher, cone energy saving ball mill and tube mill and other mill, but daily often seen in a lattice-type ball mill and overflow ball mill. Mill mainly by the circular cylinder, electric motor and the internal composition of milling facilities, the motor is rotated by drive cylinder drive ends of the cylinder cover ball bearings, polished by friction rotational movement of the cylinder barrel driven media and materials, milling After the material out of the barrel with the gravity and the other end of the steady flow of material into the ball mill. In the mill's selection should be based on actual mill grinding material to be selected, first select the ball according to the degree of wet and dry materials, due to the wet ball generally work less efficient and therefore produce more during the current dry-type ball mill. When choosing a dry ball mill ball mill liners in accordance with the actual selection of materials, such as cement clinker grinding when used mostly for overflow ball mill beneficiation mill, overflow ball mill higher productivity. And in the production of materials for those more sensitive to impurities in the material purity requirements for materials to use more higher ceramic ball, ceramic ball lined with ceramic lining because of its high production that can withstand the temperature and difficult to like Like other ball metal contamination of the material generated to change its nature. In the non-ferrous metals industry more intermittent ball mill, as well as in the production of fertilizer applications are quite extensive.
