Post Raymond grinding ore debugging considerations
Raymond mill ore for the correct installation and commissioning, is to ensure safe and efficient operation of the basic premises. However, many users are in a hurry to put into production after the installation of the ore raymond mill, ignoring the correct commissioning of the equipment, which is not conducive to the long-term operation of the milling operation. Here, we look at the mine Raymond grinding debugging considerations.
1, when the ore Raymond mill installation is completed, it is necessary to carry out the operation of the machine load test and load test run two processes. In the mine Raymond mill empty load running test machine, the first Raymond mill roller device with wire rope tied to avoid the equipment running roller and grinding ring contact impact. At the same time, it is important to note that the mine Raymond mill emptying machine can not be operated for less than 1 hour and the main machine should be stable. The oil temperature in the cabinet should not exceed 80 ℃ and the temperature rise should not exceed 40 ℃.
2, in the ore Raymond mill load test machine running process, to ensure that the test machine running time of not less than 8 hours, and pay attention to observe the operation of the Raymond mill with no noise, vibration and other phenomena to ensure that the various pipe connections Leak-free phenomenon. Raymond mill ore after the test machine to tightening of the fastening reinforcement.
3, Raymond mill ore debugging operation, pay attention to the no-load blower boot, until the normal operation of the device after loading and running. In this process, we should observe the smooth operation of equipment, and make sure that there is no abnormal sound and vibration, then put into operation again. In addition, pay attention to the operation of ore Raymond grinding, the maximum temperature of the rolling bearing shall not exceed 70 ℃, the temperature rise does not exceed 35 ℃.
4, when the ore Raymond mill run, the lower the height of the pressure spring, the greater the pressure on the mill roll material, then the higher the output of the mill. Therefore, we should according to the main motor load conditions, the pressure on the working height of the spring reasonable regulation.
