Pulverizing mill for coal processing
In coal-fired power plants, efficient pulverizing and drying of coal is crucial to ensure seamless boiler operations. The challenge lies in processing various coal types and achieving specific feed sizes while minimizing maintenance and energy consumption.
Pulverizes and dries coal for consistent feed
The Raymond Bowl Mill from Schenck Process is a high-efficiency vertical roller mill designed for drying and pulverizing coal. Notable for its ability to handle different coal types, this mill ensures optimal pulverization and classification. The system includes components such as a feeder, classifier, fan, cyclone, and dust collector which work together to meet specific material requirements. The bowl mill system can achieve 95% passing 200 mesh and offers capacities ranging from 24 to 150 stph. With an externally adjustable classifier, users can select fineness from 70% to 95% through 200 mesh without halting operations. The mill operates smoothly with no metal-to-metal contact, resulting in low vibration and noise. It accommodates bituminous, sub-bituminous, and lignite coals and petroleum coke, even with high initial moisture content up to 40% in lignite.
Benefits
- Handles a wide range of coal types
- Adjustable fineness without stopping
- High capacity options up to 150 stph
