Standard operation of fertilizer horizontal mixing machines is crucial for ensuring uniform mixing, extending equipment lifespan, and preventing material blockage, jamming, and safety accidents.

Before starting, the following checks must be performed: Clean any residual material and lumps from the machine; ensure the mixing shaft and blades are not loose or deformed; check the tension of belts and chains, and ensure the protective covers are complete and secure; ensure bearings and gearboxes are properly lubricated, and that the motor and wiring are undamaged; ensure the discharge port is closed, and that no personnel are near rotating parts; start the fertilizer produciton machine under no-load.

During startup, run the machine under no-load for 2-3 minutes to observe that the rotation is correct, there are no abnormal noises, and no severe vibrations before starting to feed materials. The material sequence should follow the order of "main materials first, then auxiliary materials; dry materials first, then liquids," and liquids should be sprayed evenly to prevent localized clumping.

During operation, monitor the machine continuously: ensure the current remains stable within the rated range. If abnormal noises, excessive vibrations, stalling, or material leakage occur, immediately stop the machine and disconnect the power for troubleshooting. Never reach into the machine to clean or repair it while it is running. If uneven mixing, shaft seizure, or material sticking to the walls are detected, stop the machine immediately for cleaning to avoid affecting the quality of the next batch.

Shutdown Procedure: First, stop feeding, allow the equipment to continue running, and completely empty the material from the machine before stopping. Never stop the machine with material still inside to prevent overload during the next startup. After shutdown, clean the inner wall of the cylinder, impellers, and discharge port to remove any residual fertilizer, keeping the equipment clean and preventing material hardening and clumping.

Routine Maintenance: Check fasteners and seals every shift and add lubricating oil regularly. Replace worn impellers and seals promptly to prevent leakage and uneven mixing. Operators must be trained and strictly adhere to safety procedures; avoiding violations will significantly reduce the risk of malfunctions and downtime, ensuring stable and efficient production.
