Abstract
A method of processing plastic material uses a device which operates in a batchwise fashion. The device includes a cylindrical container having a shaft disposed coaxially therein. The shaft is provided with mixing tools and can be driven at high speed. Material to be processed, and liquid if desired, is supplied to the container in pre-metered amounts, gelled by resultant frictional heat and granulated, if necessary, then expelled from the container. The material is supplied in a continuous, metered constant quantity stored temporarily and then fed into the container cyclically at predetermined intervals. The apparatus for carrying out the method includes at least one metering device which feeds an intermediate container and instrumentalities for cyclically emptying the intermediate container into the cylindrical container.
