As the cellulose-plastic composite exits the megacompounder at 350°F (177°C), a hot face die cutter pelletizes it in 1/8- to 1/4 in. (3.175mm to 6.35 mm) sizes. The high heat imparted by the high speed twin screw demands rapid cooling of pellets. A 30-ft (9150 mm) long, 6 in. (150 mm) diameter pneumatic conveyor transports them into a 6-ft (1825 mm) high cyclone from which they fall into the 60 in. (1525 mm) diameter circular vibrating fluidized bed processor by Kason. The processor cools the pellets to 100°F (38°C) and dries them to less than 1% moisture. The transfer between cutting chamber and cooler takes two seconds at 4000 lb/hour (1800 kg/hour).
