Coal powder is flammable and explosive, making safety the top priority in pulverizing. Shanghai Shibang integrates safety into every link, building a five-level explosion-proof system, and has completed dozens of high-risk projects with zero major accidents.
Main safety risks include coal accumulation and spontaneous combustion, high temperature, static electricity, and poor ventilation. Shibang prevents these from design, equipment, control, and management.


The five-level explosion-proof system: 1. Structural safety—optimized flow field, no dead corners, explosion-proof electrical parts, and negative pressure operation (air leakage <3%). 2. Monitoring and early warning—real-time temperature, CO/O₂ detection, and abnormal alerts. 3. Inerting and explosion suppression—automatic nitrogen/CO₂ injection to reduce oxygen to <8%. 4. Explosion relief—explosion-proof valves and isolation valves to release pressure and prevent flame spread. 5. Emergency shutdown—one-key stop, fire linkage, and independent safety PLC.
Shibang’s LM vertical mill and MTW European mill are specially designed for coal pulverizing: sealed grinding rollers, explosion-proof classifiers, and flame-retardant dust collectors. The intelligent control system realizes safety interlocking and automatic protection.
Daily management is crucial: Shibang provides safety systems, including uniform feeding, regular ash cleaning, equipment inspection, and staff training. Our standard operating procedures ensure hidden danger closure.


Shibang’s safety solutions meet international standards. Cases include a Gansu 300,000-ton project with online monitoring and nitrogen protection, both running safely.
