Introduction To Different Types Of Ball Mill
The development of ball mill equipment is closely related with technology progress
of humankind and the overall industrial level, especially with the development of the science of mechanical engineering and mining disciplines. Ball mill is the key milling equipment after material has been crushed. It is widely used in cement, silicate, new construction material, refractory material, chemical fertilizer, ferrous metal and non-ferrous metal as well as ceramics. It is widely applied to dry or wet grinding for ores and other materials.
Ball mill is the key equipment for grinding after the crush process, and it is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics, it also can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Overflow Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various

Ball mill is an efficient tool for grinding many materials into fine powder. In production, the discharging concentration of the grade ball mill is higher than the overflow one, for the former has the forcedly discharging function. If the concentration is dilute, the flow rate speeds up, impact times between the particles and the grinding medium decrease, all those will not only reduce the grinding efficiency but also speed up the abrasion of the liner and the steel ball, meanwhile the granularity tends to become coarse (known as "running coarse").
Chinaware ball mill is mainly used for mixing, milling of the materials. It works with less energy but produces high fineness product. It is suitable for mixing and milling of general and special materials. Users can choose the proper model, lining board and media as per the factors, such as: materials specific gravity and hardness, as well as output, etc. It has two types, wet mills and dry mills. The machine could use different lining board according to product requirement to satisfy different customers requirement. The milling fineness depends on the milling time. The motor is started by the coupling which can reduce voltage and lower the starting electricity. The structure is pided into integral type and freestanding type. Advantages of the machine are lower investment, energy saving, structure novelty, easy and safe to operate, stable and reliable performance, etc.
The lattice type ball mill for the horizontal tube-shaped rotating device, outer gear, the two positions, the lattice-type energy-saving ball mill. Material from the feeding device into the compound through the air shaft screw evenly into the mill first warehouse, the warehouse there are ladder liner or corrugated lining, built-in different specifications steel ball, rotating cylinder produces centrifugal force will be brought to a certain height balls After the fall of materials produced heavy blow, and abrasive.
The ball mill equipment is along with the development of the new era. The emergence of it will drive the development of a new industry chain. And with the combination with new technique and two years of infrastructure construction, the ball mill equipment has emerged the whole machinery industries into a virtuous circle. We believe that ball mill equipment industry will becoming more and more essential in the development of our economy and the machinery industry. And it will have a bigger leap! With Chinas rapid economic growth, the mining industries in the economic and social status will also rise.
