HVM Vertical Roller Gypsum Grinding Mill 2500-5600mm with 85-730t/h Capacity for Desulfurization Powder Production

Gypsum powder is a valuable non-metallic mineral widely used in construction, building materials, power generation, papermaking, paint, food, and pharmaceutical industries. Desulfurization gypsum, an industrial solid waste from flue gas desulfurization processes, can be efficiently recycled into high-value products using specialized vertical grinding equipment.

• Raw Material Moisture: <10%
• Raw Meal Fineness: R0.08<12% | R0.08<14%
• Raw Meal Moisture: ≤1%

The electric motor drives the grinding disc through a reducer, with material fed to the disc center while hot air enters the chamber. Centrifugal force moves material toward the disc edge where grinding rollers crush it in circular grooves. High-speed airflow carries crushed material upward, with large particles returning for regrinding. Dynamic and static separators classify particles, with qualified fine powder collected as product while moist materials are dried by hot gases.
