During the operation of NPK blending fertilizer production lines, several equipment failures may occur. Below are common issues and their solutions.
- Batching System Failures
Inaccurate dosing: Caused by faulty sensors in the batching scale, a damaged scale body, or incorrect control system settings.
Solution: Check for loose or damaged sensor and scale body connections. Replace or repair them if needed. Recalibrate the batching scale and ensure proper control system parameters.
- Mixing System Failures
Uneven mixing: The mixing blades of the fertilizer mixer machines are worn, the mixing speed is inappropriate, or the material ratio is incorrect.
Solution: Inspect the mixing blades for wear and replace them if necessary. Adjust the mixing speed based on material properties and mixing requirements. Optimize the material ratios to ensure accurate proportions.
- Conveying System Failures
Conveyor belt slipping: Caused by insufficient belt tension, worn rollers, or material overload.
Solution: Increase the belt tension. Check roller surfaces for wear and repair or replace them. Control material flow to prevent overloading.
- Packaging System Failures
Inaccurate packaging weight: Caused by faulty sensors in the packaging scale, a damaged scale body, or incorrect control system settings.
Solution: Check for loose or damaged sensor and scale body connections. Replace or repair them if needed. Recalibrate the packaging scale and verify control system settings.
Poor sealing: Caused by incorrect temperature settings, insufficient sealing time, or malfunctioning sealing equipment.
Solution: Adjust the sealing temperature and time based on packaging material specifications. Inspect the sealing equipment and repair or replace it if faulty.
Understanding these common failures and solutions helps maintain efficient and stable operation of NPK blending fertilizer production lines, reduces losses, and improves product quality.
