1. Equipment sealing and dust suction system: Organic fertilizer equipment should adopt a good sealing design, especially the use of sealing materials at the inlet, outlet and body connection to prevent dust leakage.

2. Dust collection system: Install efficient dust collection system, including dust collection hood, ventilation duct and dust collector. The dust collecting cover can be installed near the dust generation source to collect the raised dust; The ventilation pipe will transport the dusty air to the dust collector. The dust collector can be a cyclone dust collector, a cloth bag dust collector or a pulse dust collector, and the filtration efficiency can reach more than 99%.

3. Wet process: water is added in the grinding and mixing process for wet operation to form a water film to reduce particle friction, thereby reducing dust generation.

4. Process optimization and equipment selection of organic fertilizer production line: use low-speed grinding equipment to reduce dust flying.

5. Closed system: closed equipment is used in crushing, mixing and other links to prevent dust leakage.

6. Regular cleaning and maintenance: regularly clean the equipment surface and workshop dust, replace aging equipment and damaged seals.

7. Staff training and protection: Strengthen the safety training of employees, and properly use and wear personal protective equipment, such as masks, safety glasses, etc.

Through the above measures, it can effectively reduce the production and diffusion of dust in the production process of organic fertilizer equipment, protect the environment, ensure the health of operators, and improve production efficiency.
