Abstract
A processing facility (1) comprises a processing screw machine (4) for processing dewatered rubber (7) and styrene acrylonitrile, a dewatering screw machine (2) for dewatering wet rubber (6) and providing the dewatered rubber (7), and a feed device (3) for feeding the dewatered rubber (7) into the processing screw machine (4). Because the dewatering and the processing are mechanically decoupled, simple, flexible and efficient processing can be achieved.
Claims18
A method for processing styrene acrylonitrile, comprising the following steps:
- providing a processing facility with a dewatering screw machine and at least one processing screw machine,
- feeding wet rubber having a first water content W1 into the dewatering screw machine,
- dewatering the wet rubber by means of the dewatering screw machine to form a dewatered rubber having a second water content W2, where W2<W1,
- discharging the dewatered rubber from the dewatering screw machine,
- feeding the dewatered rubber and styrene acrylonitrile into the at least one processing screw machine,
- producing a mixture of the dewatered rubber and styrene acrylonitrile by means of the at least one processing screw machine, and
- degassing the produced mixture by means of the at least one processing screw machine.
