Abstract
A compound plant for processing elastomeric compounds for tires with both a high quality and a high throughput includes at least one batch mixing device in combination with at least one multi-shaft continuous mixing device having a high number of shafts. For example, the multi-shaft continuous mixing device could be a ring extruder having a plurality of co-rotating screws disposed to form a ring. In operation, a first elastomeric compound is discharged from the at least one batch mixing device and processed with the at least one multi-shaft continuous mixing device to obtain a second elastomeric compound.
