The Disc Pelletizers convert powdered materials into spherical pellets 500 µm to 20 mm in diameter. They 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 and pond tailings. These pelletizers are constructed of a heavy, welded, reinforced carbon steel plate, and the bottom internals of discs 6 ft and larger are lined with expanded metal to reduce abrasive wear.
