GX Electric Feeder, DS Type Electric Airlock, Star Unloader

Product Overview

The GX electric feeder, DS type electric airlock, and star discharge valve are discharge devices used for定量 conveying and air-sealing of powder and granular materials. They are widely installed in dust collector hoppers, storage bins, and material silos for ash discharge or material unloading. These products use a rotary impeller structure driven by an electric motor to continuously or intermittently discharge material evenly from the upper hopper to downstream equipment, while providing good air-tightness to prevent gas leakage between chambers.

Main Types

• GX Electric Feeder: Standard electric discharge device suitable for定量 feeding and continuous discharge of powder and granular materials

• DS Type Electric Airlock: Discharge device with strong air-sealing function, particularly suitable for sealed discharge in positive-pressure or negative-pressure pneumatic conveying systems

• Star Discharge Valve: Also known as a star-shaped discharge valve or rotary feeder — compact structure with uniform discharge — commonly used for ash discharge from dust collector hoppers

Core Advantages

• Uniform Discharge: Consistent clearance between the impeller and housing — stable discharge volume per rotation — continuous and smooth feeding

• Airtight Sealing: Precision-machined clearances provide good air-tightness — suitable for positive-pressure and negative-pressure operating conditions

• Compact Structure: Small size, light weight — easy to install — direct flange connection to hoppers or dust collector outlets

• Reliable Operation: Driven by a cycloidal pinwheel reducer or direct-coupled motor — smooth operation — low failure rate

• Wear-Resistant & Durable: Housing and impeller made of cast iron or stainless steel — good wear resistance — long service life

• Easy Maintenance: Simple structure — few wear parts — quick inspection and maintenance

Typical Applications

• Dust collector hopper ash discharge

• Hopper bottom material unloading

• Airlock feeding in pneumatic conveying systems

• Conveying of powder and granular materials in metallurgy, building materials, chemical, grain, environmental protection, and other industries
