Rotary Valves And Airlocks For Cement

Rotary valves and airlocks transfer powder or granules with a pocketed rotor while limiting air passage between pressure zones. UNIMA machines housing and rotor surfaces and assembles them according to drawings.

Product Advantages

• Rotor volume and geometry can be matched to material feeding
• Controlled rotor-to-housing clearance helps manage air leakage and mechanical contact risk
• Wear-appropriate materials support the service conditions.

Applications

• Cement, mining and bulk material lines
• Silo discharge and dosing units
• Pneumatic conveying and dust filtration systems.

Manufacturing Features

• Drawing-specific ductile iron, steel or wear-resistant material such as Hardox
• Casting, CNC turning/milling and assembly
• Clearance, CMM/dimensional and required hardness checks
• Material traceability. A rotary valve is not hermetically sealed
• allowable leakage, pressure and suitability for explosive atmospheres are determined for each project.

The dimensions, quantities, weights, delivery terms and lead times in the case record refer to the illustrated example project. They do not represent general production capacity or a delivery guarantee for other orders. The technical scope, inspection requirements and lead time of each new order are determined separately according to the drawing, material, quantity and project requirements.
