Pre-Operation Preparation
Operator Training Requirements: All milling machine operators must undergo safety training and understand the machine structure, working principles, and safety precautions before operating the equipment.
Workspace Inspection: Before operating the milling machine, inspect the machine and surrounding environment for hazardous items or obstacles. Ensure adequate clearance space around the machine for safe operation.
Electrical Safety: The milling machine power supply must use a grounded plug with proper earth connection. Never operate the machine without verified grounding protection.
Pre-Operation Inspection and Maintenance: Before starting, check the following: drive belts for cracks and wear, motor drive and lubrication system for normal operation, grinding chamber cleanliness and absence of foreign objects, roller tightness and proper positioning.
Safety Rules During Operation
Hand Safety: During normal operation, operators must never insert hands or other objects into the grinding chamber to prevent accidents and serious injury.
Workspace Discipline: When the milling machine is running, do not disturb or play with objects around the grinding chamber area, as this may affect work quality and safety.
Overload Prevention: When excessive material accumulates in the grinding chamber, reduce the feed rate immediately to prevent overload operation that could cause equipment failure.
Shutdown Protocol: After stopping the milling machine, wait for the roller to come to a complete stop before removing material and residues from the grinding chamber.
Tool Replacement Safety: When replacing grinding tools, first disconnect the power supply and wait for the roller to stop completely before proceeding with any operation.
Abnormal Condition Response: During operation, if feed inlet, discharge outlet abnormalities, belt looseness, or other irregular conditions are detected, immediately shut down for inspection and maintenance.
Post-Operation Requirements
Cleaning and Maintenance: After shutdown, clean and maintain the milling machine thoroughly. Keep equipment clean and dry to prevent corrosion, oxidation, rust, and other deterioration.
Long-Term Storage: When the milling machine will not be used for an extended period, conduct regular inspections and maintenance to preserve equipment condition.
Professional Repair Only: If problems occur during milling operations requiring repair, only qualified professional technicians may perform the work. Unauthorized personnel are strictly prohibited from attempting repairs, as improper maintenance can cause equipment failure and personal injury.
Summary
The grain milling machine requires careful and deliberate operation. Operators must understand its working principles, master normal usage methods, and strictly follow safety operation procedures to ensure both personal safety and normal equipment function.
