Stainless Rotary Feeder Unit
简介:
  • Many powder handling processes suffer from bridging, flooding, or material degradation due to standard feeder units that lack corrosion resistance and precise control. Our Stainless Rotary Feeder Unit ensures consistent, jam‑free metering even in harsh environments, reducing downtime and maintenance costs.
  • Corrosion‑Resistant Build: Entire unit made of 304/316L stainless steel with sanitary surface finish, suitable for acidic, alkaline, and wet environments.
  • Adjustable Feed Rate: Variable frequency drive allows precise rotor speed control from 0.5 to 15 rpm, enabling accurate metering for different materials.
  • Low Particle Degradation: Gentle rotor action and optimized pocket geometry minimize crushing and attrition of fragile or abrasive powders.
  • Easy Maintenance Design: Tool‑free access to rotor and wear plates; sealed bearings eliminate grease contamination; cleaning in place (CIP) compatible.

Stop Production Delays Caused by Inconsistent Material Flow

Many powder handling processes suffer from bridging, flooding, or material degradation due to standard feeder units that lack corrosion resistance and precise control. Our Stainless Rotary Feeder Unit ensures consistent, jam‑free metering even in harsh environments, reducing downtime and maintenance costs.

Product Overview

The Stainless Rotary Feeder Unit is a precision‑engineered metering device built entirely from 304/316L stainless steel. Designed for food, pharmaceutical, and chemical industries, it delivers reliable, hygienic material transfer with minimal particle breakage and zero cross‑contamination. Available in multiple rotor configurations and shaft sealing options to suit your specific application.

Product Features

  • All stainless steel construction – 304 or 316L with sanitary finish for easy cleaning and corrosion resistance.
  • Adjustable rotor speed – enables precise feed rate control from 0.5 to 15 rpm via variable frequency drive.
  • Multiple sealing options – packed gland, air purge, or lip seal to prevent leakage of fine powders.
  • Compact modular design – simplifies integration into existing pneumatic or gravity systems.
  • Low maintenance – sealed bearings and replaceable wear plates extend service life.

Pricing Information

This product is made to order. Each unit is customized based on rotor diameter, inlet/outlet size, material compatibility, and optional accessories. Request a tailored quotation by contacting our sales team with your process requirements.

Service Commitment

We provide free technical consultation during the design phase, full documentation (including CAD drawings and material certificates), a 12‑month warranty on all components, and responsive after‑sales support. Spare parts are stocked and ready for immediate shipment.
