Product Overview: Built for Abuse
Standard rotary valves are fine for sawdust. But for Boiler Ash, Cement Clinker, or Sand, you need a Rigid Impeller Feeder. The term "Rigid" refers to the rotor construction: it is cast as a solid piece or welded with thick steel plates, designed to crush small lumps that would jam a standard valve.
Key Features: Outboard Bearings
The #1 cause of failure in heavy industry is dust entering the bearings or heat melting the grease.
- The Solution: We use an Outboard Bearing Design. The bearings are mounted outside the main housing, separated by a gap and packing seals.
- Benefit 1: If the seal leaks, dust falls on the ground, not into the bearing.
- Benefit 2: It creates a thermal break, allowing the valve to handle materials up to 250°C - 400°C without cooking the bearing grease.

Anti-Jamming Design
- Shear Angle Inlet: We design the inlet with a V-shape "shear point". If a rock gets caught between the blade and the housing, the Scissor-like action cuts it or pushes it aside, preventing the rotor from locking up.
- Open-End Rotor: Prevents material from building up on the side plates of the rotor (Deep Pocket design).
Technical Data
- Model: TGF / YJD-H Series.
- Capacity: 2 L/rev to 100 L/rev.
- Material: Wear-Resistant Cast Iron or Hard-Faced Steel.
- Motor Power: Higher torque motors (1.5kW - 7.5kW) to power through resistance.
Typical Applications
- Power Plants: Handling bottom ash and fly ash (High Temp).
- Cement Plants: Discharge of raw meal and clinker.
- Mining: Feeding crushed ore onto conveyors.
FAQ
Q: What is the max particle size it can handle?
A: It depends on the valve size. Generally, the particle size should be less than 10% of the inlet diameter to prevent jamming.
Q: Is the rotor replaceable?
A: Yes. The end covers can be removed to slide out the rotor for replacement or hard-facing repair without removing the entire valve body from the line.
