WHAT CÂN A STURTEVANT AIR SEPARATOR DO IN YOUR PULVERIZING SYSTEM? In the cement industry, Sturtevant Air Separators have a tested record of increasing mill capacities from 25 to 3 0 0 % while lowering power consumption as much as 5 0 % — when used in closed circuit with grinding mills. Maybe they can do as well for you. Easily adaptable to your materials.
Sizes of Sturtevant Air Separators range from 3 to 18 feet in diameter. They deliver fines from 40 to 400
mesh at rates as high as 100 tons per hour. Designed to cut costs! Sturtevant Air Separators are built for a lifetime of low-downtime service. Rugged construction plus easy accessibility for quick maintenance (typified by the "OPEN-DOOR" design in other Sturtevant equipment) assures more output per machine-year.
