A complete list of special accessories for 1200 ball mill plum blossom cross coupling screws

In cement, metallurgy, chemical and other industrial production, various types of ball mills are responsible for important production tasks. The structures of ball mills are basically similar, including: grinding body, lining plate, inlet and outlet end cover, support bearing, large ring gear and transmission system wait. In the transmission system of the ball mill, the motor and reducer, reducer and pinion are connected by couplings. The couplings generally use elastic pin couplings. Whether the transmission system is stable and normal during operation is to ensure that the entire grinding mill is stable. The key to the normal operation of the machine, and the alignment accuracy and wear of the coupling part in the transmission system directly affect the stable operation of the transmission system. During installation and use, poor alignment or severe wear of the coupling will cause vibration and shaking of the pinions, bearing seats, reducers or motors in the transmission system. It will also cause the system to string together the shafts, causing the anchor bolts of all parts to be damaged. Loose, forcing the grinder to fail to operate properly. Our factory produces ball mills by the joint method. Various types of ball mills are one of the large-scale main equipment of our factory. Due to the continuous operation of the equipment, the transmission system of the ball mill often vibrates, shakes, loosens the foundation, and even the foundation is damaged. Therefore, it often This causes unplanned shutdowns for maintenance and affects normal production operations.
After many on-site observations of equipment failures, it was initially determined that the problem was caused by the coupling, and then the machine was shut down and disassembled to examine the cause of the failure. First, we analyze the structural forms of the two couplings used in the mill and find out the corresponding technical standards and requirements. Then compare the original design structure with the actual situation on site. Secondly, we checked the relevant dimensions of each part and found that the alignment accuracy of the two axes met the technical requirements.
