The ball mill is key equipment for regrinding. Ball mill really is popular for cement, silicate product, new type building material, fire-proof material, chemical fertilizer, black and non-ferrous metal, glass, ceramics and etc. Our ball mill can grind ore or another materials which can be grinded either by wet process or by dry process.Ball mill is definitely an efficient tool for grinding many materials into fine powder. The Ball mill can be used to grind many different types of mine along with other materials, in order to find the mine, which widely used in building material, chemical industry, etc. There are 2 means of grinding by ball mill: the dry process as well as the wet process. It could be divided into tabular type and flowing type based on variations of discharging material of ball mill.Main motor is one of the main auxiliary parts of ball mil. If the choice of the main motor is not appropriate, it often creates some wrong conditions when ball mill is running up. In order to avoid the main motor is not suitable and delays the time for the ball mill normal being put into use, we choose set up some principles for ball mill:1. Make sure that the motor should be applied forunified evaluation with the mechanical transmission of ball mill. For assessment, we should take the mechanical mill reducer manufacturing conditions into account.2. When determining the rated voltage of motor ball mill, should consider variable pressure situation of area power grid as well as the capacity of the grid size.3. You must consider other equipment motor type of the concentrator, and it is also the basis of the power factor of power network.4. The initial investment of ball mill main motor and the operation cost of ball mill must be balanced.Henan Hongxing Mining Machinery Co., Ltd (http://www.china-hxjq.com/company.html) established the international advanced production line, first-class modern testing base as well as research centers of sand maker, mill and mine-selecting equipment. Scientific management, advanced processing technology and innovative manufacturing theory make the company become the mining machinery manufacturing and exporting base in China.
