Grinding work is the continuation of the crushing process, belonging to preparation work before ore selecting. Ball mill is the most widely used machine in grinding operation. The grinding process is like this: material is fed into continuously rotating rotary cylinder, inside which different grinding bodies with various shapes, such as balls, bars, short cylinders (grinding section), large ores and gravels are installed. When the barrel rotates at a certain speed, the grinding bodies are driven in rotation and impact force will be produced which achieves grinding effect. Therefore, external force is exerted on the ball mill grinding bodies, and then transferred to the material. Therefore, the grinding bodies are also called grinding medium.
The material of the cylindrical ball mill’s barrel is steel plate, the material of the lining is ceram. And the material’s property determines the proportion size of the grinding ball mill. According to different discharging modes, ball mill can be classified into grate ball mill, overflow ball mill and wind discharging ball mill. Since it is the fine grinding equipment after the smashing procedure, the ball mill is mainly applied in the field of processing mine and grindable materials. Due to this characteristic, the ball mill is widely used in numerous industries like cement making, silicate making and building materials etc. When the ball mill is in operation, the contact ratio is small when devices mesh with each other, but the impact is huge. If any point of the gear bears excessive stress, the gear tooth is prone to break. The way to handle this is to revise and process accurately each gear’s parameters in the accelerator. To a service-oriented brand integrity,As the professional manufacturer of complete sets of mining machinery, like stone production line, Henan Hongxing is always doing the best in products and service.stone impactor:http://www.crusher-machine.com/n214.html
During the application, because of the quenching aggrandizement layer, the ball mill will be presented with the phenomenon that it can hardly support the block contact load thus being crushed and deformed. The effective way to deal with it is to reasonably optimize and design the heat treatment, ascertain the bending degree of the tooth root then through quenching strengthening to ensure a lasting support for the contact load of the machine to decrease the times of introducing the additional load as few as possible. This series of measurements aim to guarantee a stable and high-efficiency rotation of the ball mill during its operation. At the same time, it reflects the fact that a rational structure design is significant for a normal operation of a device.
Therefore, seeing from the importance of production and economic benefits, we should constantly carry out research to improve the grinding methods and technology, develop new equipment and new type wear resistant material to reduce the cost of ore processing, which will has important practical significance to reduce dressing cost and improve dressing index. It is also the reason why the ball mill research is taken seriously at home and abroad.
