1. Super fine grinder and power unit should be installed firmly. If the super fine grinder is fixed for a long time, it should be fixed on the cement foundation; if the grinder is mobile, the unit should be installed on the frame made of angle iron, and the power machine (diesel engine or electric motor) and the grinder should be guaranteed. The pulley grooves are on the same plane of revolution.

2. After the pulverizer is installed, check the fastening condition of the fasteners of each part, and tighten them if they are loose. At the same time, check whether the belt tightness is appropriate.

3. Before starting the pulverizer, first turn the rotor by hand to check whether the claws, hammers and rotor are flexible and reliable, whether there is any collision in the shell, whether the rotation direction of the rotor is consistent with the direction indicated by the machine arrow, the power machine and the pulverizer Whether the machine lubrication is good.

4. Do not replace the pulley casually, in case the speed is too high to cause the crushing chamber to explode, or the speed is too low to affect the working efficiency of the grinder.

5. After the pulverizer is started, it should be idling for 2~3 minutes first, and then start feeding if there is no abnormal phenomenon.

6. Pay attention to the operation of the pulverizer at any time during work, and feed materials evenly to prevent clogging and stuffy cars, and do not work overloaded for a long time. If vibration, noise, excessive temperature of the bearing and the body, or material spraying out are found, stop the machine immediately for inspection, and continue working after troubleshooting. Add grease to the oil nozzle at any time to protect the normal operation of the bearing and prolong the service life of the bearing.
