General Specifications: Raw Material Moisture <15%, Product Specific Surface Area ≥420 m²/kg, Product Moisture ≤1%

• High grinding efficiency with 40-50% lower energy consumption compared to ball mills
• Large single-machine production capacity with low-valley electricity utilization
• Hydraulic system allows grinding roller extraction for easy maintenance and liner replacement
• Roller sleeves can be flipped to extend wear-resistant material service life
• No-load startup capability eliminates difficult starting procedures
• Extended service life with special material grinding rollers and disc liners

Electric power, metallurgy, cement, chemical industry, non-metallic minerals. Suitable for processing: cement raw meal, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, and bauxite materials.

The motor drives the grinding disc through the reducer, with material entering from the feed inlet. Hot air enters the mill, and centrifugal force moves material to the disc edge where grinding rollers crush it. The dynamic separator classifies particles, returning coarse material for regrinding while collecting fine powder as the final product. Moisture control is achieved through hot gas contact during processing.
