Attention Should Be Paid on the Operation of Ball Mill

The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet. The proportion of the mill-exit material returned to the inlet may vary from 10-30% when ordinary cement is being ground, to 85-95% for extremely fine cement products. It is important for system efficiency that the minimum amount of material of finished-product fineness is returned to the inlet. Modern separators are capable of making a very precise size "cut" and contribute significantly to the reduction of energy consumption, and have the additional advantage that they cool both the product and the returned material, thus minimizing overheating.Between balance wheel and middle wheel of ball mill gear box, mesh, Tooth elevation do not install according to the regulation, this will cause the ball mill high speed shaft pinion drives one side intermediate shaft big gear wheel, while ball mill intermediate shaft pinion drives balance wheel, ball mill balance wheel drives the other side intermediate shaft that makes ball mill gear box cannot form two sides load sharing rotation, occur beat voice, it is dangerous.According to the discharge situation of ball mill, the output of accepted products refers to the actual ball load of the same kind beneficiation plan t to makes sure the reasonable ball load of this ball mill, then test for at least 72hours.If the wheel gear sounds slight beat or hoarse friction voice, and run well, you can observe continuously and find out the problems, ball mill should be stop and process; if the sound becomes louder, you should stop the machine immediately and check it.rod mill: http://www.fote-machine.com/product/mbs-type-rod-mill.html
