Common causes of wear on organic fertilizer equipment include the following:

1. Break-in wear: This is the most common normal wear and tear on organic fertilizer equipment. When new friction surfaces begin to rub, the wear rate is rapid. As the actual contact area between the friction surfaces increases, the unit pressure decreases, and the wear rate also decreases.

2. Corrosion wear: Continuous penetration of media such as water vapor, chemical gases, or oxides between the friction surfaces causes oxidation and deterioration. These are generally oxidative wear and chemical corrosion wear.

3. Dust: Organic fertilizer production lines generate a certain amount of dust during operation and after discharge. If not cleaned and maintained promptly, dust can enter the various joints within the equipment. Over time, friction at these joints increases, and it can even lead to the accumulation of pathogens, causing corrosion and impacting equipment performance.

4. Inadequate lubrication: Long-term use of equipment puts a severe test on its lubrication. Once jamming occurs, friction increases. Only high lubrication can provide good power support for the operation of organic fertilizer equipment.

5. Uneven feeding: Uneven feeding can lead to uneven loading on both ends of the turning teeth, causing more material on one side and less on the other. This can increase equipment wear.

The above analysis demonstrates that wear on organic fertilizer equipment can be caused by a variety of factors, including the equipment's physical properties, the operating environment, and operator behavior. To reduce equipment wear and extend its service life, comprehensive measures are necessary, encompassing equipment selection, operating procedures, and routine maintenance.
