Air Swept Classifier Mill System

Air Swept Classifier Mill System

The CMS Air Classifier Mill System combines impact grinding and particle size classification in a single continuous process (occurring inside the mill) rather than in a separate downstream process. Independent drives for the classifier wheel and impact rotor allow the operator to adjust each component’s rotational speed independently. Drag and tip speed control the product’s sizing. The efficiency of air classifier mills allows the grinding and classification to occur inside the mill, rather than in a separate downstream process. CMS Air Swept Classifier Mills are available from 1 HP (horsepower) to 600 HP.

The grinding zone configuration positions Impact Hammers mounted at the periphery of the Rotor Plate (below the Classifier Wheel). A ring-shaped Reversible Liner (smooth or multiple-deflector liner) surrounds the Rotor Plate and Hammers. A Deflector assembly (shroud/baffle), located above the Impact Rotor between the Liner and Classifier Wheel, constitutes the grinding zone. The space between the Classifier Wheel and Deflector assembly forms the classification zone.

Mill Operation

Air is drawn into the grinding chamber via the air inlet feed, flowing upward from below the Rotor Plate (disc), and dispersing the material through the grinding zone. There, the rotating Impact Hammers impact the feed material and deflect particles into the mill’s Liner, which is configured in a way to slow the circumferential speed of the particles. The Liner deflects the particles back to the hammers, adding impact force. Size reduced particles flow to the Deflector Assembly, which diverts the particles into the classification zone. Fine particles pass through the classifier wheel vanes, (flowing to the product-and-air outlet), while coarse particles return to the grinding area for further reduction.

Separate drives for the classifier wheel and impact rotor allow you to adjust each component’s rotational speed independently. Drag and tip speed control the product’s sizing.
