Experience what a revolution in design can do for your operation. The modular design of our rotary valve makes service and repair a snap. The materials and workmanship provide the tight tolerance and long-lasting durability that you need from a metering or airlock device.
The PMR rotary feeder combines a stationary tool-steel knife and a rotor with helical vanes to provide a shearing action for cutting off oversized materials in a feedstock, minimizing jamming or interruption of the feed. Functionally, the PMR is both a metering device and an airlock. PMR feeders are built for long, continuous operation with provisions for eventual rebuilding.
A Self-Cleaning Rotary Valve? Absolutely!
Material build-up in the pockets of rotary valve can be a real problem. Throughput can be reduced or become inconsistent. You’ve got to stop production and clean it out. The Precision PMDS Self-Cleaning rotary valve is a reliable, trouble-free solution to this problem.
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.
Feeding raw materials and clinker in a cement manufacturing plant is a demanding job. Huge volumes of abrasive materials and 24/7 operation for months at a time add up to a real challenge for rotary feeders. Precision’s PMCA family of feeders were specifically designed for these tough conditions.
Fuel bin and transport screws for moving mixed, wood-based fuels from storage to the boiler or kiln. Designed for holding up to abrasive, poor-quality fuels, Precision’s fuel handling screws are built for extreme-duty and to run from outage-to-outage with no downtime.
Extreme-duty, abrasion-resistant screw conveyors for moving fly ash and bottom ash away from boilers. Fly ash at 250° F and bottom ash at 600-700° F require materials and designs that tolerate continuous exposure to elevated temperatures.
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.
A high-capacity rotary feeder for introducing cement raw materials, principally quarried limestone, into a vertical roller mill (VRM) or another type of raw mill. U
The Precision Micro-Valve’s innovative design was developed to handle small to medium applications. It is ideal for metering a precise amount of an additive to an in-process application.
Precision PMA rubber-tipped airlocks are a heavy-duty, fully fabricated airlock intended for use with mild to moderately abrasive materials where a tight airlock seal is required.
Let our applications specialists help you with your extreme-duty bulk material handling needs.
