Heavy-Duty Rotary Airlock Feeder with Hardened Tool Steel Knife

Maximum Durability | Precision Shearing | Engineered for Consistent Material Flow

Looking for the most rugged and efficient rotary airlock feeder on the market? Precision Machine & Manufacturing’s Heavy-Duty Rotary Airlock Feeder with Hardened Tool Steel Knife is engineered for extreme-duty performance in pneumatic conveying, bulk material metering, and dust collection systems.

This feeder is the industry’s go-to solution for challenging materials like wood chips, pulp, plastics, rubber, and biomass. The stationary tool steel knife shears oversized material at the infeed, reducing bridging and blockages while ensuring consistent particle size to downstream equipment such as boilers, gasifiers, pneumatic conveying systems, digesters, or presses.

Key Features:

  • Heavy-Duty Construction: Built to withstand extreme industrial wear and tear.

  • Hardened Tool Steel Knife: Provides reliable, precision cutting and reduces system wear.

  • Consistent Material Flow: Optimizes throughput and minimizes downtime caused by blockages.

  • Wide Industry Use: Ideal for biomass, wood processing, recycling, and alternative fuel applications.

  • Rebuildable Design: Reduces total lifecycle costs and maximizes ROI on capital equipment.
