ABSTRACT:
A process for cooling rubber crumb wherein the rubber crumb is presented for cooling to a first stage pneumatic conveyor containing a hot wet first stage air stream. The rubber crumb is cooled in the first stage pneumatic conveyor to a first temperature, whereupon the cooled rubber crumb is separated from the first stage air stream and transferred to a second stage air stream of cool dry air. A second stage pneumatic conveyor transports the rubber crumb in the second stage air stream for additional cooling.
