Wood, Organic & Alternative Fuel Materials

Rotary Airlock Feeder w/Knife

#
Functionally, the PMR is both a metering device and an airlock. PMR valves are built for long, continuous operation with provisions for eventual rebuilding.

High Volumes of Fly, Pond & Bottom Ash

Double Slope Rotary Airlock Feeder

#
A durable high-capacity rotary feeder for handling dry powders, granular materials, small rocks, or other abrasive materials with relatively uniform material size and low moisture content. Offers an attractive capacity-for-cost ratio compared to tight-tolerance rotary valves. Functionally, both a metering device and an airlock.

Ideal for Sticky & Low Moisture Materials

Self-Cleaning Rotary Valve

#
Metering and airlock application for handling very large volumes of limestone and other raw materials. Typically used with a VRM (vertical roller mill).

NFPA Compliant- Perfect for Powdery and Granular Materials

Extreme Duty Rotary Valve Airlock

#
A superior, long-lived modular rotary valve for metering and airlock applications handling powders or small granules. It offers unmatched durability compared to competing solutions and is engineered and built for the most difficult applications in a plant.

The Ideal Solution for Delicate & Breakable Materials

Side-Entry Rotary Valve Airlock

#
A long-lived offset or side-entry rotary valve designed to minimize shearing and breakage in the handling of delicate, formed, molded, granular, or pelletized materials. Functionally, PMSE valves are both a metering device and an airlock.

Called Upon for the Most Difficult Applications

Extreme Duty Screw Conveyors

#
No need to settle for an “off-the-shelf” solution, when you can have a customized screw conveyor that will perform better and last longer – for the same cost!
