1. Appearance inspection surface treatment: check whether the surface of the equipment is smooth and flat, and there are no obvious welding defects, scratches or rust. High quality equipment usually has a good surface treatment and no obvious defects.

2. Coating quality: Check whether the coating of the equipment is uniform and firm, and whether there is shedding or foaming phenomenon. The coating quality directly affects the corrosion resistance of the equipment.

3. Manufacturing process: Check whether the welding part is smooth and firm, and there is no virtual welding and leakage welding phenomenon. The welding quality directly affects the structural strength of the equipment.

4. Assembly accuracy: Check the assembly accuracy of the organic fertilizer equipment, whether the components are firmly installed and whether there is loosening. Equipment with high assembly accuracy runs more stably.

5. Overturning parts: Check the quality and wear of overturning parts (such as roulette, stirrer, etc.). High quality pile turning parts have strong wear resistance and long service life.

6. Safety device emergency stop device: Check whether the equipment is equipped with an emergency stop button, and whether the emergency stop button is sensitive and reliable.

7. After-sales service technical support: understand whether the supplier provides comprehensive technical support and after-sales service, including equipment installation and commissioning, operation training, maintenance and so on.

Through the inspection and evaluation of the above aspects, the quality problems of the equipment of the fermentation pile turning machine can be effectively identified, and the high-quality and high-performance equipment can be selected to ensure the smooth progress of the production process and the long-term stable operation of the equipment.
