1. Ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground.
2. Ball Mills 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 Classifiers, such as screens, Spiral Classifiers, cyclones and air Classifiers are used for classifying the discharge from ball mills.
3.  Ball mill is an efficient tool for grinding many materials into fine powder. The ball mill is used to grind many kinds of mine and other materials, or to select the mine. It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry process and the wet process.
4. Ball mill can be divided into tabular type and flowing type according to different forms of discharging material.
According to ball mill’s basic functions,we can obtained lareger capacity final products.welcome to our factory .we have more than 50 years ball mill production experiences,and already passed internation certification,such as ISO9001 and ISO14000.

Professional Suggestion For Controlling Rod Mill’s Production Cost
rod mill cost can be lowered if paying attention to the following points:
Rod mill can bring two apparent superiorities .The first is high grinding efficiency. When rod mill runs, the roller directly mills on the ring. While traditional Ball Mill Machine still adopts some coarse rod mill working principle, the rod mill can save energy about 30-40%.
Besides the rod mill is a whole set including crushing, drying, grinding and grading conveyor together, so the entire system of the Vertical Mill is simple and the layout is compact enough. Compared with vertical mill, the area on the ground of rod mill is about 50 percent of that and you don’t need anything to cover the mining machine. It’s unnecessary to put the grinder mill in a room. Here you can see that the rod mill cost is much lower than vertical mill which will significantly reduce the rod mill investment. Another point is that during the running of rod mill, hot air will be direct in touch with material when we can get different humidity materials just by changing the temperature of hot air.
There is no doubt that we will save a great amount of energy,and then saved a lot of money.
