Heavy-Duty Rotary Valve Airlocks specifically for the demanding Coal-Fired Power Generation Industry

High-volume coal-fired power generation plants require Rotary Valve Airlocks capable of standing up to the abrasive qualities of coal, which can also deliver high volumes of lower-quality lignite coal just as effectively as higher-quality bituminous or subbituminous coal, while maintaining airlock functionality in a high-temperature environment. With a proven history of performance, PMM is the coal-fired power generation industry’s preferred airlock!

NFPA Compliant-Powdery & Granular Materials

Extreme Duty Rotary Valve Airlock

#
This heavy-duty rotary valve airlock is the preferred rotary airlock due to its industry leading, ultra tight rotor to housing clearances and abrasion-resistant materials. This airlock is perfect for handling powdery or small granule materials.
High-Volumes of Ash, Granular & Powdery Materials

Double Slope Rotary Airlock Feeder

#
A durable high-volume, heavy-duty rotary airlock feeder manufactured from abrasion resistant materials and designed to move massive amounts of low moisture granular and/or powdery materials types such as fly, pond, or bottom ash.
Perfect for Low Quality Coal Applications

Self-Cleaning Rotary Valve Airlock

#
The self-cleaning heavy duty rotary valve airlock is the perfect metering airlock for the efficient handling of high-moisture materials such as lignite coal that are subject to sticking, packing, and/or clogging the material handling system.
Perfect for Eliminating Material Breakage

Side-Entry Rotary Valve Airlock

#
An offset inlet enables this heavy duty rotary airlock to handle materials of relative uniform size while minimizing shearing and breakage of delicate, formed, molded, granular, or pelletized material types.
Wood, Organic and Alternative Fuel Materials

Rotary Airlock Feeder w/Knife

#
A combined metering device and a heavy duty airlock in one. Equipped with a hardened tool steel knife so oversized materials are reduced prior to entering the delivery system. This Rotary Airlock Feeder is the preferred choice for moving alternative fuels.
Called Upon for the Toughest Applications

Heavy-Duty Screw Conveyors

#
Designed to meet the unique needs of the application and manufactured by hand to ensure the highest possible quality, PMMs heavy duty screw conveyors are superior in every way to “off-the-shelf” augers.

  • Failure is not an options! Producing energy is demanding and very few rotary airlock manufacturers are up the task of successfully supporting this demanding industry! PMM manufactures extremely durable Rotary Valve Airlocks that are capable of meeting the specific needs of the Coal-Fired Power Generation industry.
  • Rotary airlocks should NEVER be the weakest link in your emission control and DSI environmental systems. We understand 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 brown coal without sticky build-up! No matter where lignite coal is being introduced into the process, PMM has Rotary Valve Airlocks that can consistently and reliably feed brown coal while minimizing the potential for clogs.
  • Working with super abrasive pet coke? No problem! We specialize in building Rotary Valve Airlocks for high-abrasive environments that last longer and requires far less maintenance.
  • Rebuildable! Unlike common cast-iron airlocks, all PMM Rotary Valve Airlocks are rebuildable! This provides a greater ROI over the life of the product and significantly reduces CAPEX spend, along with overall maintenance costs.
