I. Pre-cleaning Preparation
1. Empty the material.
Ensure there is no residual material in the grinding chamber to prevent deterioration and corrosion.
Turn off the power and release system pressure (e.g., hydraulic/air pressure).
2. Tool Preparation.
Prepare a cleaning solvent (select a neutral detergent or specialized solvent based on the material properties).
Equip a high-pressure water gun, soft-bristle brush, and rust-proof oil.
II. Core Cleaning Steps
1. Circulation Cleaning.
Pour cleaning fluid into the circulation tank and start the machine at low speed (speed ≤ 30% of rated value). Circulate and clean for 15-20 minutes, focusing on flushing the grinding chamber, pipes, and screens.
2. Disassemble and Clean Key Components.
Remove the filter and iron remover. Use an ultrasonic cleaner to remove stubborn dirt (oily materials require soaking with an organic solvent). Check the screen clogging rate; if it's >50%, replace it.
3. Cooling System Treatment
Drain the cooling water (antifreeze is required in winter; use antifreeze when the ambient temperature is <0°C).
Use compressed air to blow out any remaining moisture in the pipes.
III. Rust Prevention and Protection
1. Lubrication and Protection
Apply anti-rust oil (such as WD-40) to bearings, guide rails, and other metal parts.
Inject food-grade grease into the spindle seal.
2. Moist Storage
Inject a small amount of solvent or pure water into the grinding chamber to keep it moist to prevent the seal from drying out.
IV. Post-Shutdown Inspection
1. Environmental Control
Store the equipment in an ambient humidity ≤ 60% and a temperature of 5-40°C. Cover with a dust cover to prevent dust accumulation.
2. Recording and Archiving
Record cleaning time, solvent usage, and any abnormalities.
