"ZG/JH" Series Multi-Functional Rotary Feeder- The Core Solution for Integrated Material Handling and Conveying

Rotary Feeder Product Overview

The "ZG/JH" Series Rotary Feeder (commonly known as a rotary valve, discharge valve, or air lock valve) is a modular, multi-functional core material handling equipment developed by our company, integrating decades of mechanical manufacturing experience and material technology. Designed to meet the material characteristics and process requirements of various industries, this series provides comprehensive solutions ranging from heavy-duty wear resistance and food-grade sanitation to high-precision airtightness. Whether handling abrasive slag, fine fly ash, or precious grains, the "ZG/JH" series delivers exceptional performance, reliable stability, and lasting durability, making it an indispensable component in your pneumatic conveying, quantitative feeding, and air lock feeding systems.

 

Versatile Applications, Extensive Coverage

With its flexible and adaptable design, the "ZG/JH" series is perfectly suited for numerous industries and complex materials:

  • Heavy-Duty Wear Resistance: Specifically designed for highly abrasive and hard materials such as cement, coal slag, mineral slag, and silica sand. Applied in cement plants, thermal power plants, steel metallurgy, and mining industries for silo discharge and conveying transfer.
  • Powder Airtightness: Offers excellent airtightness for ultra-fine powders like fly ash, cement, carbon powder, and lime powder, which are prone to dusting. Ideal as an air lock feeder in pneumatic conveying systems and a discharge valve under dust collectors.
  • Food-Grade Sanitation: Constructed entirely of stainless steel to meet food-grade sanitary standards, specifically used for precise metering and contamination-free conveying of grains, feed, and food raw materials (e.g., wheat, flour, sugar, milk powder).
  • General Industrial Applications: Quantitative feeding and packaging of granular materials such as chemical plastics and grains.
