Coal powder is vital fuel for thermal power boilers, aluminum carbon materials and silicon metal smelting. Coal dust is flammable and explosive, demanding strict explosion-proof, dust removal and temperature control for grinding machines. Traditional asynchronous motor mills consume huge power, leading to high long-term production electricity cost. SBM launched PMD Permanent Magnet Direct Drive European Grinding Mill specially built for explosion-proof coal powder preparation scenarios.
The machine uses permanent magnet direct drive motor to eliminate multi-stage gear transmission. Power transmission loss approaches zero, cutting comprehensive energy consumption by 20%–30% compared with traditional mills. Full explosion-proof electrical components, anti-static air ducts and flame-proof motors are equipped. Spark detection and temperature early warning devices eliminate hidden dangers of coal dust explosion and fully satisfy safety specifications of carbon factories and power plants.
Adjustable powder size covers 0.038–1.6 mm. Hourly capacity from 6 tons to 55 tons fits coal powder projects with annual output of 200,000–500,000 tons. Negative-pressure sealed circulation matches explosion-proof pulse dust collector with over 99% coal powder recovery rate without dust leakage. Multiple carbon factories in Gansu and Inner Mongolia adopt PMD permanent magnet direct drive models. Power cost drops obviously after three years of stable operation with zero safety accidents.
A full explosion-proof coal powder production line includes raw coal crushing, sealed silo, PMD explosion-proof main mill, spark detection dust removal and sealed jumbo bag packing system. SBM holds complete qualifications for coal powder projects and provides safety process design, full explosion-proof equipment supply and commissioning to meet safety supervision standards.
If you plan coal powder preparation projects for carbon factories or power plants and need energy-saving explosion-proof grinding equipment, send production capacity and workshop conditions via online consultation. Our engineers draw complete process drawings and offer quotations for explosion-proof coal powder lines.
Summary: PMD permanent magnet direct drive European mill integrates explosion-proof structure. Zero-loss power transmission reduces power cost. It is developed specially for coal powder preparation with sealed dust removal for carbon and boiler fuel processing.
