Rotary Vane Feeder

1. Product Overview

The Industrial Heavy-Duty Rotary Vane Feeder (also known as a rotary chute or revolving plow feeder) is a premier volumetric material extraction solution designed for heavy-duty industrial bulk handling. Positioned directly beneath massive circular storage bins, slot bunkers, or blending silos, this equipment uses a rotating arm assembly to continuously and uniformly extract material and deposit it onto downstream belt conveyors. It is highly effective in managing difficult, abrasive, or cohesive bulk solids—such as run-of-mine ores, coal, limestone, and sinter—ensuring a perfectly regulated production flow in mining, metallurgy, power generation, and cement facilities.

2. Detailed Description

This feeder consists of a heavy-duty vertical pedestal base that houses a high-precision slewing bearing and an enclosed oil-bath reduction gearbox. The rotating superstructure extends an engineered vane or discharge chute outward, sweeping across the bottom opening of the storage silo. As the drive motor rotates the assembly, it breaks the material’s natural angle of repose, pulling it down evenly via gravitational and mechanical force. The entire structural frame is heavily reinforced to absorb high impact forces and static pressures. To accommodate fluctuating process demands, the system integrates advanced variable frequency drives (VFD), allowing plant operators to precisely accelerate or decelerate the rotational speed for automated, real-time control over plant throughput.
