摘要:
A process for continuously producing an elastomeric composition includes metering at least one elastomer, at least one filler, and at least one minor ingredient; feeding the at least one elastomer, the at least one filler, and the at least one minor ingredient into at least one extruder; mixing and dispersing the at least one filler and the at least one minor ingredient into the at least one elastomer using the at least one extruder; obtaining a subdivided product from a resulting elastomeric composition discharged from the at least one extruder; accumulating an amount of the subdivided product; and stirring the accumulated amount of the subdivided product. An apparatus for continuously producing an elastomeric composition includes at least one extruder, at least one first metering device, at least one second metering device, at least one device for obtaining a subdivided product, and at least one accumulating and stirring device.
