The motor drives the grinding plate via reducer, with material fed centrally. Hot air enters from air inlet, and centrifugal force moves material toward edge where grinding rollers crush it. High-speed airflow lifts crushed material, with coarse particles returning for regrinding. Dynamic and static separators ensure only fine powder exits with airflow to collection system.

• Large production capacity with low energy consumption and environmental compliance
• Reversible roller sleeves extend service life and improve output
• Integrated explosion-proof devices ensure operational safety
• Advanced bearing design eliminates need for sealing fans
• Simplified slag removal system reduces maintenance requirements
