The crushing machine should be fixed on the cement foundation. If the work place is changed frequently, the grinder and motor should be installed on the frame made of angle iron. If the diesel engine is used as power for the grinder, the power of the two engines should be matched, that is, the power of the diesel engine is slightly larger than the power of the pulverizer, and the two belt pulley grooves are identical. The outer end of the pulley should be on the same plane. Before starting, it is necessary to check whether the bolts of each part of the unit are fastened, whether the tightness of the transmission belt is suitable, and whether the power cord is good. Whether the shaft of the motor is parallel to the shredder shaft.
It
Check whether the hammer is good, whether the aperture of the screen is suitable or not. Drag the belt by hand to check whether the spindle rotates flexibly, whether there is a card or a friction phenomenon. After starting, turn the equipment for 2 to 3 minutes, check whether the rotor is correct, and whether the sound is normal. It can work only if the rotation speed is stabilized at rated speed. In the work, we should pay attention to the operation of the grinder at any time, so that the feeding should be uniform, so as to prevent clogging, and not to work over a long time. If there is vibration, noise, bearing and body temperature is too high, the phenomenon of spraying outside, should immediately stop checking, troubleshooting can continue to work.

The crushed materials should be carefully checked, and no foreign matter such as stone or metal can be mixed to avoid damaging the machine. When the machine runs, the operator may not leave the unit, nor can it be used in the operation to observe the work of the comminuted room, and the maintenance tools shall not be placed on the machine or the packing. Operators do not wear gloves, when there is a blockage, the hand is strictly prohibited into the stuffing bucket, when feeding should stand on the side of the crusher, in order to prevent the rebound of debris to hurt the face. Do not stop immediately after the work is finished. You should turn around for 2 to 3 minutes in order to completely discharge the material inside the machine. After the shutdown, the cleaning and maintenance work should be carried out.

Hammer is the main vulnerable part, after wear, whether it is the same direction change angle or turn the turning angle, all the hammer pieces should be changed at the same time. When the new hammer is replaced, the whole set of hammer is also changed at the same time, and a new change can not be made with a single hammer. Sieves are also vulnerable parts, such as part of the screen is damaged, riveting can be damaged, serious damage to replace the new screen. After 300 hours of operation, the bearing must be cleaned and the oil changed. When you stop for a long time, you should unload the belt.
