Heavy Duty Raw Mill Clinker/Limestone Rotary Airlock Feeder-Delivers up to 800 MTPH!

Engineered specifically to meet the rigorous demands of the Cement Manufacturing industry, the heavy duty Raw Mill Rotary Airlock Feeder is designed to feed up to a massive 800 tons per hour of highly abrasive clinker limestone into the raw mill delivery system, and doing so while providing superior airlock functionality! In addition to being rebuildable, which provides a superior return on CAPEX investment over its life, the Raw Mill Rotary Feeder requires minimal maintenance.

Manufactured using U.S. sourced, 500 Brinell abrasion-resistant steel alloy, and precisely engineered to ensure the tightest possible rotor to housing clearances to maximize airlock functionality. The PMM Raw Mill Rotary Feeder is frequently called upon to replace the maintenance-heavy triple gate or flap gate systems.

Simply put, Precision Machine & Manufacturing’s Raw Mill Rotary Airlock Feeder is the raw mill airlock the Cement Manufacturing industry trusts and it has many years of operational experience to prove it!
