Handling abrasive materials like cement, clinker, and raw meal requires absolute durability. In pneumatic conveying systems, even a millimetric deviation or wear in the clearance between the rotor blades and the housing can lead to severe pressure losses, material jamming, and costly production halts.

At UNIMA, we engineer solutions for extreme environments. We manufacture high-precision rotary valves (airlocks) designed to resist severe abrasion and maintain perfect sealing efficiency. Utilizing our advanced CNC machining capabilities, we process heavy-duty materials with tight tolerances to ensure flawless material flow and optimal airlock performance.

Product & Engineering Info:

• Material Options: Rotors and housings machined from high wear-resistant materials such as Hardox, hardened carbon steel, or customized alloy castings tailored to your abrasion requirements.

• Machining Precision: Tight-tolerance CNC milling and turning ensure the exact millimetric clearance between the rotor and housing, maximizing system pressure retention and preventing mechanical blockages.

• Quality Assurance: We operate on a zero-defect principle. Every rotary valve component undergoes rigorous dimensional inspection via CMM and material hardness testing to guarantee long-lasting performance against abrasive dust.

• Application Areas: Pneumatic conveying systems, silo discharges, dust collection filters, and raw mill feeding in the Cement, Mining, and Heavy Machinery sectors.

Production Capacity: Scalable custom batch production tailored to your project deadlines, with full material traceability and precise clearance measurement reporting at every stage.
