Ball mill includes the shell, and the liners made by wear resistant material shall be fixed in the shell, loading with shell and maintain its rotating bearing, as well as driven part, such as motor, drive gear, pulley, V-belt, etc. Ball mill is the important grinding equipment, which generally will be regrinded after crushed materials, can do the dry or wet grinding operation for the all kinds of ores and other grinding materials, widely used in cement, port land products, refractory material, chemical fertilizer and glass ceramics production, also used in the beneficiation, building materials, chemical and other industries.
The shell of ball mill is the main part of ball mill, which is made of cylindrical thin shell welded with steel plate and installed different shapes of liners and storehouse plates, also has the small holes in shell itself for maintenance and filling. The shell is a kind of part with dynamic load and be in long-time running at low speed, also is the main part of ball mill. So must consider if parts need to be replaced in the design, to ensure that the safety and reliable work and long time use. It is essential to ensure the roundness of shell and welding quality in the manufacture.
Protect the ball mill shell can increase the life of the iron ore beneficiation equipment.According to the grinding process, each warehouse is different to the requirement of the grinding body motions, for example, to enter the first grinding warehouse material block is larger, this requires the impact of the grinding medium have to be big enough, only after each grinding storehouse, the impact strength decreases gradually.Until finally, minimum impact strength requirement, grinding the most aggressive.
Iron ore equipment of ball mill lining and lining part is used to protect the cylinder grinding body from grinding medium and material of the direct impact of friction.Different shapes of liner can also change the movement of grinding medium and material on the inside of warehouse.So, ore dressing equipment of ball mill grinding effect mainly depends on the impact of the grinding medium on material and grinding effect.
Because different shapes, in according to the specific requirements of warehouse to equipped with different ratio of the size of the grinding medium, make the lining board and produce different friction between the grinding body, to change the grinding body motion, thus to improve the grinding efficiency.Grinding medium and the majority of the liner material with high wear-resisting coefficient of rubber and higher than major aluminum ball stone.
