Mill Information: ball speed impact on the grinding efficiency. Speed ??ball mill time affects the motion state of ball mill grinding media and the material, but also due to changes in the rotational speed of the grinding media and material movement mine mill doing different manufacturers, slag mill manufacturers, ball mill grinding efficiency also occurs in different states of motion changes. Ball mill grinding media and the material inside the ball at different speeds, the movement can be divided into the following three states: the fall-speech movement; Paola style movement; centrifugal movement. Mill normal working condition for dropping the type or diarrhea fall-sports. By observing the test and practice analysis, the more the greater the amount of near Ball Mill, grinding media, give full play to the role of the outermost layer of crushed material to, in order to make bigger mill grinding efficiency. By known theoretical calculations, the outermost angle from the grinding media is 54.73 degrees, the outermost layer can obtain the maximum drop height, the material most effectively grind. From the practice found that when adjusted to the speed of the ball mill work critical speed of 0.75-0.85 production mill manufacturers can make within the media mill at a higher drop height, to achieve the best grind state. Xiao Bian first day they encountered bright sunny day, the mood is exceptionally good, and today we continue to explain the use of a ball mill failure may occur during some solutions. Simplified connection with the hollow shaft ball screw loose fracture: ball hollow shaft and simplified connection under normal circumstances are hollow shaft flange, flange and simplified conducted with open hole, while leaving two to three articulation hole with tape wire buckle pin pinned vias connecting with ordinary screws, pin hole is to locate and stop. In the mill operation, the distortion due to thermal expansion and contraction, temperature and water vapor corrosion, mill articulation pin and the pin hole with the size change, loose, not limited to location, under the distorting effects, others are beginning to loosen the screws , ball and cylindrical hollow shaft misalignment occurs periodically. Shear and tensile forces, over time, the screws began to break, starting helpless, broken on the exchange, put on continuing fracture, and later after repeated analysis mill manufacturers, 50% of the connecting screws to hinge pin connection system , once again breaking phenomenon has not been seen.
