Wood, Organic and Alternative Fuel Materials

Rotary Airlock Feeder w/Knife

#
The Rotary Airlock Feeder w/Knife is both a metering device and an airlock. Equipped with a hardened tool steel knife so oversized materials are sheared to a common size before entering the delivery system. The Rotary Airlock Feeder w/Knife is the preferred choice within industrial manufacturing industries than handle wood, biomass materials, plastic, rubber, and various alternative fuels.

Precision Solutions

  • We get your challenges. When others are turning their backs on the coal industry, we’re doubling down to help our coal fired power plant customers operate efficiently, meet the growing demand, and deal with the complex environmental regulations, while also generating a profit. Here at PMM, we can be counted on to offer solutions to problems!
  • Rotary valves should NEVER be the weakest link in your emission control and DSI environmental systems. Precision understands the importance of precise, reliable injection of lime, trona or activated carbon to keep these systems performing as specified. Our solutions offer longer life, efficient waste-free use of materials.
  • Move lignite without sticky build-up that plagues competing units. . No matter where you’re feeding lignite into your process, Precision has rotary valve and rotary feeders that feed consistently and reliably, minimizing the potential for clogs and maximizing process throughput.
  • Working with super abrasive pet coke? No problem! Unique solutions and high-abrasive environments are our specialty. Let us recommend a solution that lasts longer and requires less maintenance.
  • Rebuildable! All PMM material handling components are rebuildable! This provides a greater ROI over the life of the product and significantly reduces CAPEX purchases and overall maintenance costs.
