Abstract: Petroleum coke features strong abrasiveness. This content describes grinding workflow, PMD direct-drive technology and how to reduce wear-part consumption for coke grinding projects.
Petroleum coke contains green coke and calcined coke. After fine grinding, petroleum coke powder serves as metallurgical carburizer, industrial fuel and raw material for carbon material production. Calcined petroleum coke shows relatively high hardness and strong abrasiveness, bringing heavy burden to grinding equipment’s wear components. If wear-resistant performance of mill is insufficient, roller and ring will wear quickly and cause frequent spare part replacement and high running cost. The mainstream finished product fineness of petroleum coke powder stays at 200-325 mesh.
Standard petroleum coke grinding workflow includes raw material crushing, iron removal impurity elimination, buffer silo storage, quantitative feeding, grinding, air classification and finished product collection. Iron remover must be installed before main mill to eliminate iron blocks mixed inside coke raw material and protect internal grinding components. Ventilation and dust collecting design should be optimized to avoid accumulated fine coke dust risk.
For medium and large-size petroleum coke powder processing projects, PMD Permanent Magnet Direct-Drive Pendulum Mill provides competitive solution. This mill innovatively applies permanent magnet direct-drive motor, cancels complicated traditional gear-transmission structure, improves transmission reliability and achieves around 15% comprehensive energy-saving rate. On-line intelligent lubrication system supports non-stop long-time operation. Multi-point running condition monitoring collects vibration, temperature and load real-time data and sends fault early warning. Mobile APP remote-control function reduces onsite labor requirement.
Feed material up to 50 mm can be accepted. Finished powder can be adjusted from 80 mesh to 400 mesh, matching carburizer and fuel-grade petroleum coke powder specification. According to coke abrasion feature, SBM can provide customized high-wear-resistant roller and ring options. The complete grinding line runs under fully sealed negative-pressure state, matched with pulse dust collector to prevent coke dust leakage and satisfy environmental protection rules.
Many buyers only compare machine price but underestimate petroleum coke's abrasion. After commissioning, they suffer short service cycle of vulnerable parts and increased operating expense. Raw coke type, feed granularity and target powder index should be clarified at project preliminary phase.
If you are planning petroleum coke grinding production-line investment, please submit your project information via page message or business consultation. Tell us coke type, feed size, target capacity and mesh requirement. Our technical team will recommend proper wear-resistant upgrade and full-set equipment configuration.
Summary: This article introduces petroleum coke material property and end uses, analyzes high-abrasion challenge. It presents PMD mill advantages and key points for coke powder plant construction.
