Attention-some Problem About Ball Mill In Grinding Process

Ball mil is commonly used for grinding equipment in mining machinery, often used to process slag. Ball mill in the slag crushing applications requires some careful consideration.

Crushed slag must first select the line of the ball mill equipment. At present, the slag powders, widely used abroad vertical ball mill and separator ring composed of the production process flow system, the very use of individual enterprises, but most small ball mill open flow system. Because the production of vertical ball mill main features are:stand-alone high output, low energy consumption, but the time investment is large, domestic general business unbearable.The small ball mill open and there are stand-alone production of low production, high energy consumption, product fineness is not easy to control defects, it is difficult to assume the task of mass production. However, ball mill has a long history and mature technology, reliable operation, simple, widely used in the cement plant, which is its advantage.Therefore, we believe that use a large ball mill, as the slag grinding is a choice in line with China's national conditions, lower investment yields and product quality stable and reliable.

Large particles of slag materials contain only small, relatively uniform particle size, particle size and more concentrated in the 1 ~ 60mm. Therefore, in order to control the particle size into the mill, in order to facilitate optimal size distribution, as long as the points according to pre-screen grid can be. Slag on the ball mill equipment wear depends on the content of iron and iron oxide. Because iron has plasticity, it is difficult to be finely ground in grinding equipment. Will gradually set in the grinding system attached, resulting in ball mill for further wear. To avoid this disadvantage, should be promptly removed iron.

Ball milll through the transformation,unique screening device and grate holes arranged in the form of changes to adapt to different requirements than the surface area of ??slag powder. In addition, ball mill lining diaphragm plate and take specific technical design, to effectively improve the efficiency of the broken slag. Ball mill in the slag crushing note of these issues, we can remove the unnecessary barriers to better development.
