Coal pulverization grinding mill
Maximize efficiency in pulverizing coal with continuous operation and low maintenance, ideal for high-throughput power generation needs.
Pulverizes and Dries Coal and Biomass
The Raymond Ball Race Mill from Schenck Process is designed for efficient grinding and drying of coal, biomass, and various industrial materials. This system features a low-maintenance design, utilizing large diameter hollow balls for consistent pulverization and reduced metal-to-coal contact. Operating within industries such as energy, steelmaking, and chemicals, it ensures optimal size reduction for products like pulverized coal for power generation and granulated fertilizers. Capable of handling up to 40 metric tons per hour, it offers energy efficiency by consuming significantly less power compared to traditional tube mills. The mill is adaptable, functioning at various fineness levels and temperatures to accommodate different material characteristics and moisture contents up to 15%. The system’s integration into existing lines is seamless, providing continuous operation with minimal oversight required, thanks to its robust construction and reliable performance.
