The Doebritz External Bearing Drawer-Type Rotary Valve (Star Unloader) is an advanced material handling equipment. It functions as an ultra-reliable rotary airlock, achieving consistent feeding and absolute gas sealing within complex powder pneumatic conveying systems.
Fine dust and penetrative powders can easily destroy standard valve bearings. Built to survive these harsh, high-dust conditions, our specialized rotary valve is widely deployed in mineral processing lines, chemical powder handling, battery material conveying, cement plants, and heavy-duty dust collection systems.
Our star unloader incorporates specific features from our core design standards to solve fine dust handling challenges directly:
To guarantee stable and reliable operations under aggressive industrial stress, our equipment operates flawlessly within verified engineering parameters:
| Specification | Details |
|---|---|
| Material | Stainless Steel (SUS304 / SUS316L) |
| Working Pressure | -0.5 to 2 bar |
| Working Temperature | -10 to 150°C |
| Max Capacity | 110-634 L/min |
| Power Supply | Customized based on specific bulk density loads |
| Structure Design | Quick Dismounting (Drawer-Type) / External Bearing |
Integrating this Doebritz rotary valve provides immediate, tangible value to your processing plant. It actively reduces material leakage, completely protects bearings from dust damage, and significantly lowers maintenance costs and downtime through its highly accessible drawer-type design.
A: By moving the bearings outside the main material flow area and utilizing a double sealing mechanism, it ensures that even highly penetrative dust cannot reach or destroy the rotating mechanical parts.
A: Absolutely. With precise internal clearances and excellent pressure isolation capabilities, it acts as a highly reliable airlock specifically suited for both vacuum and positive pressure conveying (-0.5 to 2 bar).
A: Maintenance is incredibly straightforward. The "Quick Dismounting" drawer-type mechanism allows operators to slide out the rotor in seconds to inspect clearances, wash away caked powder, and resume operations rapidly.
