Through-Type Rotary Feeder
简介:
  • Dust leakage and material blockages in pneumatic conveying systems often lead to production downtime and product waste, costing you both time and money. Our Through-Type Rotary Feeder eliminates these issues with a continuous, sealed, and reliable material transfer solution.
  • Durable Construction: Housings and rotors are made from heavy-duty stainless steel or carbon steel with optional hard-facing to resist abrasive materials.
  • Low Maintenance Design: Quick-access end covers and replaceable wear parts allow for fast on-site servicing without special tools.
  • Versatile Material Handling: Handles powders, granules, flakes, and fibrous materials with consistent metering accuracy across a wide flow range.
  • Customizable Seal Options: Choose from standard lip seals, purged gland seals, or labyrinth seals to suit pressure, temperature, and dust-tight requirements.

Pain Point

Dust leakage and material blockages in pneumatic conveying systems often lead to production downtime and product waste, costing you both time and money. Our Through-Type Rotary Feeder eliminates these issues with a continuous, sealed, and reliable material transfer solution.

Product Description

The Through-Type Rotary Feeder from Headpowder is a robust, airlock-style valve designed for bulk material handling in dilute-phase pneumatic conveying. It serves as both a feeder and a seal, ensuring a steady flow of powders, granules, or pellets while maintaining system pressure. Its straight-through design minimizes material degradation and bridging, making it an ideal choice for industries ranging from food processing to chemical manufacturing.

Product Features

  • Continuous, vibration-free feeding with adjustable speed control.
  • Straight-through housing reduces material shear and particle breakage.
  • Replaceable wear sleeves and end plates for extended service life.
  • Multiple rotor configurations (open-end, closed-end, adjustable tip) to match your material.
  • Compact footprint with standard flange connections for easy integration.
  • Optional shaft seals, purge connections, and abrasion-resistant coatings.

Pricing

Each Through-Type Rotary Feeder is engineered to order based on your specific material properties, flow rate requirements, and installation conditions. Please contact our sales team for a custom quotation with lead time and shipping details.

Service Commitment

We provide comprehensive pre-sale engineering support to select the correct rotor type, housing material, and drive configuration. After purchase, you receive detailed installation manuals, a standard warranty on components, and access to our technical support hotline. Replacement parts are stocked for fast dispatch.
