I. Safe Operation
Personal Protective Equipment
Safety goggles: Prevent eye injuries caused by flying abrasives.
Protective overalls: Block impact from ejected shot.
Earplugs or earmuffs: Reduce permanent hearing damage from equipment noise.
Protective gloves: Shield hands from scratches and abrasion.
Safety Facilities
Safety guardrails: Prevent staff from accidentally entering hazardous zones.
Emergency stop button: Enable immediate power cut in case of accidents.
Warning signs: Clearly mark dangerous areas and standard operating procedures.
Prohibited Operations
Do not stand close to the blasting nozzle to avoid abrasive impact injuries.
Never perform maintenance while the machine is running; maintenance work may only start after full shutdown and power disconnection.
Do not overload the equipment to prevent mechanical damage and safety accidents.
II. Equipment Inspection & Maintenance
Pre-operation Checks
Check abrasive storage level: Ensure sufficient shot to avoid idling operation.
Separator inspection: Check for blockages and screen integrity.
Electrical system inspection: Examine damaged wiring and verify normal motor operation.
Real-time Monitoring During Operation
Temperature monitoring: Stop the machine and inspect components if the temperature of motors, bearings or other parts rises abnormally.
Noise monitoring: Unusual noise indicates potential equipment failure.
Vibration monitoring: Excessive vibration signals loose or worn parts.
Regular Cleaning & Maintenance
Periodically clean the blasting chamber, separator and pipelines to remove accumulated dust and residual abrasives.
Lubrication Maintenance
Regularly apply lubricating oil to bearings, chains and moving parts to reduce wear.
Component Inspection
Routinely check the operating status of motors, exhaust fans and screens; replace worn parts promptly.
III. Process Parameter Control
Blasting Abrasive Parameters
Abrasive type: Select suitable media (e.g., steel shot) based on workpiece material.
Abrasive grain size: Match grain size to processing requirements; oversized shot leads to defective surface treatment.
Abrasive flow control: Adjust shot volume according to workpiece material and thickness to avoid over-blasting and workpiece damage.
Operating Airflow Parameters
Air volume adjustment: Maintain proper separator airflow to prevent excessive loss of usable abrasives.
Operating Speed
Conveying speed adjustment: Set running speed based on workpiece material and technical standards to guarantee consistent processing quality.
IV. Daily Equipment Maintenance
Daily operational inspection: Check for abnormal noise and vibration before startup.
Lubrication check: Confirm adequate lubrication on bearings, chains and moving assemblies.
Electrical inspection: Inspect cables, plugs and circuits for damage.
Regular separator maintenance: Clean the separator frequently to prevent buildup of residual shot and dust.
Screen inspection: Check screen wear regularly and replace damaged screens immediately.
Fan inspection: Ensure stable fan operation and consistent airflow.
V. Workpiece & Environmental Requirements
Workpiece Preparation
Clean workpieces thoroughly to remove surface oil and rust, improving blasting efficiency.
Secure workpieces firmly to prevent shifting or falling during blasting.
Environmental Requirements
Adequate ventilation: Reduce dust accumulation and lower explosion hazards.
Ambient temperature control: Avoid operating under extreme high temperatures to guarantee normal heat dissipation.
VI. Emergency Handling
Emergency shutdown: Cut off power immediately and inspect equipment if overheating, abnormal noise or violent vibration occurs.
Fault log recording: Document fault phenomena, handling steps and results in detail for subsequent analysis.
VII. Personnel Training
Operational Training
Equipment familiarization: Train operators on machine structure, functions and safety regulations.
Emergency drills: Teach operators emergency stop procedures and basic troubleshooting.
Safety awareness training: Reinforce safe operation awareness to ensure full compliance with operating standards.
