Lime 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 classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills. 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. It can be divided into tabular type and flowing type according to different forms of discharging material.Lime ball mill is with low power consumption, only forty percent to sixty percent of ball mill and raymond mill, The life of wearing parts is long, and it is without dust-free powder and noise pollution, and its yield is high, the system operation under the atmospheric pressure closed loop, recovery reaches almost one hundred percent,. It is with small volume, simple structure, and convenient maintenance and can grind flammable and explosive and soft sticky material. The limestone ball mill can produce with open-circuit single machine production, used in the low requirement for product size condition. The discharge granularity is commonly between 20 meshes and 80 meshes, with cement mill to compose of closed-circuit, to do pre-grinding. This can improve the output of ball mill, lower unit power consumption, also can consist of loop circuit with grading machine, conveyor. Product fineness can be eighty mesh to four hundred meshes, the classifier has high efficient centrifugal classifier, and high-efficiency rotor classifier, and adopts vertical bucket elevator as conveyor equipment. high strength grinding mill:...
