Modified asphalt equipment involves high-temperature heating, mechanical mixing, colloid milling, and pressure pipeline systems. Strict operating specifications must be followed to prevent scalding, fire, mechanical injury, and equipment damage.
1. Pre-Operation Safety Preparation
Operators must receive professional training and be familiar with equipment structure, process flow, and emergency procedures.
Wear high-temperature protective clothing, heat-insulating gloves, protective masks, and goggles.
Check that all instruments (temperature, pressure, level) are accurate and valid.
Confirm that heating systems, pipelines, valves, and colloid mills are intact and free of leakage.
Remove all flammables, combustibles, and debris within the working area.
Check fire extinguishing equipment and ensure it is in effective condition.
2. Feeding Safety Rules
Strictly prohibit moisture, rainwater, or ice from entering the mixer or tank to prevent splashing and bumping.
Feed materials in the correct order and at a controlled speed to avoid overflow or blockage.
Do not put oversized or hard impurities into the colloid mill to avoid damage.
Stand aside during feeding to avoid scalding by splashing high-temperature asphalt.
3. Heating & Temperature Control Safety
Heat gradually and strictly control temperature within the process range.
Do not leave the equipment unattended during heating.
Once over-temperature occurs, immediately cut off the heat source and start the alarm procedure.
Prohibit open flames near the tank body, thermal oil pipelines, and exhaust ports.
Regularly check for thermal oil leakage, which may cause fire hazards.
4. Mechanical Operation Safety (Stirring & Colloid Mill)
Do not open the inspection cover during operation of the mixer or colloid mill.
Never extend hands or tools into the mixing chamber or feeding port.
Ensure the safety interlock system is effective before starting.
If abnormal noise or vibration occurs, stop the machine immediately for inspection.
Start and stop equipment in the correct sequence to avoid damage or blockage.
5. Pipeline & Pump Safety
Check valves before startup to avoid wrong closing or misoperation.
Operate valves slowly to prevent pressure impact and leakage.
Regularly inspect pipelines for cracks, aging, or loose flanges.
Do not stand in front of pipe joints and flanges during high-pressure operation.
6. Electrical & Explosion-Proof Safety
All electrical parts must meet explosion-proof standards.
Do not privately modify circuits or replace electrical components.
Keep control cabinets clean and free of asphalt dust.
Ensure reliable grounding to eliminate static electricity.
7. Emergency Handling
In case of asphalt fire: use dry powder fire extinguishers or fire blankets — DO NOT USE WATER.
In case of scalding: carry out first aid immediately and seek medical help.
In case of blockage or overpressure: stop feeding, lower temperature, and release pressure slowly.
In case of power failure: close main valves and heat source to prevent material backflow.
8. Post-Operation & Maintenance Safety
Clean residual asphalt and materials after shutdown.
Cut off power and heat sources before maintenance.
Wait for temperature to drop to a safe level before overhauling.
Record operation data, faults, and maintenance conditions for traceability.
9. Environmental & Site Safety
Prohibit random discharge of high-temperature asphalt and waste materials.
Keep the site ventilated to prevent harmful gas accumulation.
Non-operators are strictly prohibited from entering the production area.
Conclusion
Strict compliance with safety operation rules is the basic guarantee forstable production, equipment life, and personal safety.All operators must follow standardized procedures to avoid accidents.
