1. The pulverizer and power unit should be installed firmly. If the grinder is fixed for long-term operation, it should be fixed on the cement foundation; if the coal gangue crusher is mobile, the unit should be installed on a frame made of angle iron, the power engine (diesel engine or electric motor) and the grinder The pulley grooves are in the same plane of rotation.
2. After the crusher is installed, check the fastening of each part of the fasteners, and tighten them if they are loose. At the same time, check whether the belt tightness is appropriate.
3. Before starting the pulverizer, turn the rotor by hand to check whether the claws, hammers and the rotor are running flexibly and reliably, whether there is any collision in the shell, and whether the rotation direction of the rotor is consistent with the direction indicated by the arrow of the machine. Whether the machine lubrication is good.
4. Do not change the belt pulley casually, in case the speed is too high to cause explosion in the crushing chamber, or the speed is too low to affect the working efficiency of the crusher.
5. After starting the crusher, it should run idling for 2~3min, and then feed the material after there is no abnormal phenomenon.
6. Pay attention to the operation of the crusher at all times during work, and the feeding should be even to prevent blocking the car, and do not overload the work for a long time. If there are vibrations, noises, excessive temperature of the bearings and the machine body, or spraying materials, the machine should be shut down immediately for inspection, and the work can be continued after troubleshooting.
