After Raymond Mill is installed, it needs to carry out no load operation and debugging. It is mainly used to detect whether there is any error in the installation. If there is any mistake in the installation method, it will cause failure in the production process, so it needs empty operation, that is, No load operation.
Empty load station test machine, before the no-load test machine, the roller device is fastened with steel wire rope to avoid impact between the grinding roller and the grinding ring. Then the main engine runs empty for not less than one hour. The main machine should maintain the balance during operation. The oil temperature in the box shall not exceed 80 degrees. The direction of rotation of the main machine and the analyzer shall be correct. The fan shall be turned on without load. It shall be loaded after the normal operation. Observe the balance of the fan during operation and keep it running smoothly with no noise. Vibration phenomenon occurs, rolling bearing temperature can not be higher than 70 degrees; load operation time is not less than 8 hours, always observe the operation of Raymond Mill, after the mill is working properly, the whole machine should have no abnormal noise and vibration, and each pipe link is sealed Strictly, there is no leakage of air leakage. After the machine is shut down, it is necessary to check whether there is any looseness in the screw part and it can be put into normal production after fastening.
