1. Equipment failure: organic fertilizer crusher parts may be worn, loose or damaged, resulting in reduced operating speed.

2. Uneven feeding: During the feeding process, if the organic fertilizer block size is different and the density is different, it will affect the operating speed of the crusher.

3 Motor failure: The motor is the core component of the crusher, if the motor speed is unstable or damaged, it will lead to a decrease in the operating speed of the entire organic fertilizer equipment.

4. Transmission system problems: the transmission system includes belts, gears and other components. If the transmission system is seriously worn or damaged, it will affect the operating speed of the crusher.

5. Improper maintenance of the machine: the operation status of the organic fertilizer grinder that has not been maintained for a long time may be affected, resulting in a reduction in speed.

6. Excessive load: When the load of the organic fertilizer mill is too large, the operating speed of the equipment will be affected.

7. Environmental factors: such as temperature, humidity and other environmental factors may also affect the operating speed of organic fertilizer shredders.

8. Improper operation: The operator may not correctly operate according to the equipment instructions, resulting in degraded equipment performance.

To solve these problems, the following measures can be taken:

1. Check and maintain the equipment regularly to ensure the normal operation of the parts;

2. Ensure the uniformity of feeding and avoid large organic fertilizers entering the equipment;

3. Control the load within a reasonable range;

4. Strengthen operation training and guidance to ensure that operators perform correct operations according to the equipment instructions.

5. Perform regular performance testing on organic fertilizer shredders to discover and eliminate potential problems in time.
