First, the pulverizer must be fixedly installed, and the axis of the pulverizer pulley and the power machine pulley should be parallel. The two transmission pulley grooves must be on the same straight line. Otherwise, not only the acceleration of the machine is damaged, but also the belt is easy to fall off.
Second, if the pulley needs to be modified, it must be calculated to meet the needs of the spindle speed of the crusher. Do not increase the spindle speed arbitrarily. When the speed rating is 15%, it will cause severe vibration of the machine.
Third, the raw materials should be carefully cleaned beforehand, and if necessary, sieved or selected to prevent iron pieces, stones, etc. from entering the machine.
4. Before each use, open the pulverizer cover and check the various parts inside the machine for damage, especially if the cotter pin on the rotor is intact and the connection is loose. When the confirmation is intact, close the cover and screw it into the handwheel on the door. Drag the belt by hand to check whether the moving part is flexible, with or without abnormal noise and card collision.
5. After the machine is started, it needs to idle for 2-3 minutes. After the machine is running normally, it will be gradually added.
6. The operator should tighten the cuffs and wear masks. It is strictly forbidden to wear gloves. When feeding, stand on the side of the crusher to prevent rebound debris from damaging the face. When crushing long stem crops, the hands should not be pinched. The hand was hit by a crop pulled back.
Seventh, the material should follow the principle of “evenly feeding, a small amount of quick additionâ€, that is, from less to more, until the load is normal, and keep continuous and uniform to prevent “crashingâ€.
8. If there is a jam in the inlet, do not use wooden sticks and iron rods to prevent the stick from being brought into the machine or popping the wounded person. It is not allowed to reach into the material port and can be used with hard stems. The raw material is pushed into the crushing chamber.
9. Pay close attention to the operation. If vibration, abnormal noise, blockage or outward spraying is found, stop it immediately and check it out. It is strictly forbidden to use the wooden stick or hand to forcibly feed or pull out the material without stopping the machine, so as not to hurt the arm or hit Bad machine.
10. It is strictly forbidden to open the door when the pulverizer is running; the belt drive should be equipped with protective devices; it is forbidden to overload the machine for a long time; all kinds of tools should not be placed on the pulverizer and materials to avoid falling into the machine; smoking is prohibited in the workplace. Pay attention to waterproof and moisture.
11. The self-made powder bag should be made of breathable fabric, and the length is not shorter than 1.5 meters. If the powder bag is not breathable or too short, it may cause the feed port to be sprayed back.
12. Before stopping the machine, the material should be stopped first, and the material in the standby line should be stopped after the machine is discharged. After the operation, it should be dusted and lubricated in time.

Adjustment points
There is a gate or baffle in the lower part of the hopper, and the feed amount can be controlled by adjusting the opening of the ram or baffle. For example, when processing hawthorn vines, the vines should be chopped and the length should not exceed 150 mm. By controlling the amount of feed, work efficiency and crushing quality can be improved to avoid overload.
Generally, the pulverizer has two or three kinds of screens with different pore diameters, and different sieve sizes can be replaced when used, and different pulverization sizes can be obtained. When installing the screen, the lap joint of the screen joint should be correctly selected according to the rotation direction of the rotor, so that the direction of the inner joint is the same as the direction of rotation, so as to avoid blocking the material; if the screen mesh is tapered, due to the small hole end Usually there are a small number of burrs, in order to facilitate the discharge, the large hole end should be facing outward.
When the pulverizer equipped with the air pump adjusts the pulverization size, it can also be controlled by adjusting the size of the damper.
