Disc Pelletizers

FEECO’s Disc Pelletizers are the equipment of choice when uniform pellet size and ease of control are important when converting powdered materials into round spherical pellets of 500 micron to 20 mm diameter. Pellet sizing, based on disc angle, disc speed, and locations of solid and liquid feed, is easily controlled through the operational flexibility of FEECO disc pelletizers. 

Laboratory and pilot scale tests will determine optimum flow schemes, equipment sizing and scale up. If lab tests reveal that alternative agglomeration methods such as briquetting or extruding is the method of choice, FEECO can accommodate those processes as well.

If agglomeration with a disc pelletizer is the method of choice, further savings can be realized with lower investment, power consumption, and maintenance costs.

FEECO’s Disc Pelletizers can agglomerate fine, dry feed materials such as chemical powders, limestone, fertilizer, coal fines, cement / lime kiln dust and flyash as well as wetter materials such as filter / centrifuge cake, minerals, ores, vibrating sludges and pond tailings.

All Disc Pelletizers made by FEECO is constructed of heavy, welded, reinforced carbon steel plate (A) all inner disc bottoms six feet and larger are lined with expanded metal to reduce abrasive wear. (B) The disc angle is easily adjusted from 40° to 60° horizontal by a hand-wheel operated jacking screw (C). The base, and (D) the plow support members provide maximum rigidity while simultaneously allowing rapid pan angle adjustment, without the need for separate plow adjustment. (E) Individually mounted vane type plows easily control and maintain the product layer over the disc’s entire surface. Larger pelletizers feature ceramic facings. (F) The pivot base, a rotating member, is mounted on heavy-duty anti-friction bearings.

Automatic lubrication is featured on larger discs. Precision cut, heat-treated matched spur gear sets are featured on pelletizers over 20′ in diameter. All discs 20′ and less are directly mounted on the output shaft of a specially designed parallel shaft reducer.
