Rotary Valve for Cement, Fly Ash and Mineral Powder

Cement, fly ash, lime and mineral powders are often abrasive and dusty. FUWEI designs heavy-duty rotary valves for silo discharge, dust collection and pneumatic conveying in construction material and power plant systems.

Main Challenges

• Abrasive powder accelerates rotor and casing wear
• High dust load requires reliable shaft sealing
• Hot material may require bearing protection or cooling design

Recommended Configuration

• Cast iron or steel body for heavy-duty service
• Wear-resistant coating or hard surface when needed
• Rotor clearance matched to pressure and material abrasiveness

Data for Selection

• Material temperature
• Capacity and bulk density
• Pressure difference
• Flange size and continuous operating hours
