SELF-CLEANING ROTARY VALVES

PMDS Rotary Valve

#
Documents
REQUIREMENTS
Metering and airlock application for handling very large volumes of limestone and other raw materials. Typically used with a VRM (vertical roller mill).
PRECISION SOLUTIONS
  • Extreme-duty PMCA rotary feeders in sizes from 150 to 1000 TPH.
  • Constructed of Tri-Braze abrasion-resistant steel.
  • Hot-air design for raw material applications.
  • Transitions for slide-out/slide-in replacement of competitive feeders.
KEY DIFFERENTIATORS
  • Two years of operation between rebuilds
  • Reduced false air induction
  • Low or no recurring maintenance

CHIP & PULP FEEDERS

Rotary Feeders

#
REQUIREMENTS
Functionally, Precision’s Rotary Feeder is both a metering device and an airlock. Precision Rotary Feeders are built for long, continuous operation with provisions for eventual rebuilding.
PRECISION SOLUTIONS
  • Meter abrasive minerals and powdery materials.
  • Built with specialty 500-Brinell abrasion-resistant alloys
  • High-Temp!
  • Save energy!
KEY DIFFERENTIATORS
  • Minimial rotor-to-barrel clearances limits blowby.
  • Upgrade abrasion-resistant barrels can double the cycle between rebuilds.
  • Rebuildable!

DUST COLLECTION VALVES

PMSE Side-Entry Rotary Valve

#
REQUIREMENTS
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.
PRECISION SOLUTIONS
  • Tight tolerances-Minimizes blowby!
  • Keeps the trapped air from escaping!
  • Precisely meters the material!
  • Easily handle a variety of material types and sizes.
KEY DIFFERENTIATORS
  • Pneumatic line injectors.
  • Extremely durable. Built with 500 Brinell wear parts.
  • Rebuildable! No throw away components here!

FLY & BOTTOM ASH FEEDERS

PMRD Rotary Feeders

#
REQUIREMENTS
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.
PRECISION SOLUTIONS
  • Combined durability & functionality.
  • A metering device AND airlock.
  • Able to easily process massive amounts of fly and bottom ash.
  • Maximum throughput.
KEY DIFFERENTIATORS
  • Rounded rotor pockets
  • Ion-nitride treated to provide exceptional durability and abrasion-resistance.
  • Low or no recurring maintenance
