Abstract: Particle size of calcined coke powder determines quality of carbon products. PMD permanent magnet direct drive pendulum mill processes calcined coke and produces qualified fine powder for prebaked anode production.
Calcined coke is carbon raw material made from petroleum coke after high temperature calcination. It has high carbon content and good conductivity and serves as base material for aluminum prebaked anode, graphite electrode and carbon block. Carbon production sets strict control on particle size and gradation of calcined coke powder. Powder indicators directly affect green anode density, resistivity and quality of baked products. Calcined coke is brittle and flows easily. Its dust carries explosion risk. Traditional pendulum mills have large transmission loss and slow speed response, which cannot meet safety and energy saving demands of carbon workshops. PMD Permanent Magnet Direct Drive Pendulum Mill from SBM is optimized for carbon materials such as calcined coke and preferred for carbon fine powder processing.
Standard dry grinding workflow: raw material crushing and screening → impurity and iron removal → silo buffering → metered feeding → grinding and compressing → air classification → finished product collection. PMD permanent magnet direct drive design removes conventional reducer to cut transmission loss and lower power consumption. Stepless speed regulation cooperates with high precision classifier. Fineness can be adjusted from 200 to 800 mesh to satisfy particle gradation of different carbon formulas.
Optimized sealing structure can be matched with explosion proof dust removal units to reduce carbon powder accumulation risk and comply with safety rules for carbon workshops. The mill runs steadily with reinforced wear resistant parts for continuous calcined coke grinding. The whole line works under sealed negative pressure for centralized dust collection and less powder leakage.
Many carbon manufacturers ignore volatile content and gradation requirements of calcined coke. Single grade powder cannot meet anode formula needs. PMD mill can work with screening system to produce multiple powder grades for flexible gradation. The permanent magnet motor is reliable and easy to maintain, cutting downtime loss for carbon plants.
