Abstract
An interstage separator for transferring polymeric crumb from a first stage pneumatic conveyor with hot wet air, to a second stage pneumatic conveyor with cool dry air. The interstate separator is characterized by a tangential inlet for the crumb, and an enclosed separating chamber within which the crumb is separated from the first stage air stream. A transition member associated with the separator directs the crumb into a second stage air stream and, then, to a second stage pneumatic conveyor. The interstage separator transfers the rubber crumb from the first stage air stream to the second stage air stream without fouling of the associated equipment.
