Methods for reducing noise from organic fertilizer equipment include equipment selection, layout optimization, sound insulation, and equipment maintenance. The following are some specific measures:

1. Select low-noise equipment: When purchasing equipment, prioritize low-noise organic fertilizer processing equipment.

2. Optimize equipment structure: Choose equipment with a well-designed and optimized structure. For example, a horizontal crusher can increase the linear speed of the material being crushed, thereby reducing noise.

3. Arrange equipment appropriately: Place high-noise equipment away from office and residential areas as much as possible, and avoid clustering equipment to minimize noise accumulation.

4. Install vibration damping devices: Place vibration damping pads, such as rubber pads or spring shock absorbers, between the equipment base and the supporting structure. These pads can effectively absorb and dampen vibrations generated by equipment operation, reducing noise.

5. Use sound-absorbing devices: Install sound-absorbing materials or silencers, such as sound-absorbing cotton or foam plastic, around the equipment or in ventilation ducts to absorb and reflect sound waves, reducing noise transmission.

6. Regular Inspection and Maintenance: Strengthen routine maintenance of your organic fertilizer production line to prevent high noise levels caused by abnormal equipment operation. For example, regularly check the lubrication status of your equipment and refill lubricant promptly.

7. Replace Worn Parts: Promptly replacing worn gears, bearings, and other components can significantly reduce equipment noise.

These measures can effectively reduce noise levels from your organic fertilizer production line, improve the production environment, and minimize the impact on surrounding residents.
