Moving Materials Is What We Do!

Precision’s full line of components handle the day-to-day challenges that are unique to a variety of industries.

The Precision Difference

Compare the difference between cast iron and machined manufacturing.

Traditional
Cast-Iron
Valve

  • Performance
    Cast-iron molding process compromises performance due to loose tolerances and an average-ranking hardness rating of 270 Brinnell.
    Operational temperature limit of about 260 F.
  • Reliability
    Cast iron molding process makes maintaining minimal clearances between hardened surfaces challenging.
    Limited performance from variations in atmospheric temperatures and/or humidity.
  • Durability
    Cast-iron valves are NOT rebuildable! Replacement is required if a single component fails.
    Cast iron wears considerably faster, increasing air intake into the valve and
    decreasing performance.
VS

PMM
High-Performance
Valve

  • Performance
    Machined to extremely tight tolerances using alloys with a 500 Brinnell hardness rating for a precision airlock, precise metering and a much quieter operation.
    Operational temperature ranges from -40 F to 1,000 F.
  • Reliability
    Machined to the tightest possible clearance without binding, a machined valve will provide
    the highest level airlock functionality.

    Manufactured to function within a range of temperatures. Allows for expansion and contraction due to variations in operational temperatures.
  • Durability
    All PMM valves are completely rebuildable. Individual components can be replaced when
    worn out.

    PMM Valves are made from abrasion resistant materials, which makes them 2-3X’s more durable.

Why Precision?

Desing

Designed for reliable outage-to-out-age service in your plant and are designed to handle either raw materials or clinker. The robust design and abrasion-resistant materials provide longer life on all Precision feeders.

Industry leaders

Manufactured to extremely tight, industry-leading internal tolerances between the rotor and housing, which minimizes false air introduction into the grinding mill.

Made in USA

Precision Machine & Manufacturing’s line of Feeders, Airlocks and Metering Valves are made in USA and built to the highest of standards with steel that has been manufactured in the United States of America!

Precision has been a wonderful supplier of a great valve that has served us well. -Mineral Processing Purchaser, Washington

CEMENT INDUSTRY
Lower Total Costs. Keep Material Moving.

Whether you’re moving coal, alternative fuels, dust collection, silo discharge, kiln feed, or other high-volume, high-abrasion raw materials, Precision equipment will keep it moving, consistently, easily and without constant operator intervention. No more need to worry about material flow or assigning employees to fix clogs and spills.

Feeders and valves that fail unexpectedly and cause unplanned downtime cost you production and profitability. With Precision Predictable Performance, feeders and valves last for their rated life. Address routine maintenance and rebuilding on your schedule.
