a process for the recovery of dry polymer , wherein a polymer material containing water and / or volatile hydrocarbons is extruded through a die sleeve , cut into particles by means of a cutter mounted at the die discharge , and carried away from the cutter by an air stream . the die sleeve is provided with a plurality of die holes possessing a non - circular derived shape , which allow the material to be dried at lower temperatures and pressures . the cutter is a cage - type cylinder presenting large open areas for the flow of conveying air , thereby significantly reducing the local air velocity through the cutter and tearing of the particles . a bypass is provided to insure sufficient air being present after the cutter region to prevent condensation and to provide crumb transportation through the transport conduit . the invention reduces the generation of fines and results in an increase in the average particle size .
