Abstract: Apparatus for dewatering and drying plastic granulate comprising a multistage dewatering rotor having conveyor and aerating blades and surrounded by a screening member located within a housing between a product inlet and a product outlet. In order to simplify the handling of a wide variety of plastic granulate with only a small amount of space being required, a collection container which is open at its top coaxially surrounds the first stage of the dewatering rotor and accumulates separated water in a reservoir region for discharge by a suction pump. The product inlet discharges into a feed vessel secured in the collection container. The first stage of the dewatering rotor is provided on its circumference with worm segments of increasing pitch in the direction of granulate conveyance.

Abstract: In a process for mixing and proportioning a plurality of mixing components, the latter are supplied in individually weighed manner to a continuous mixing process and the mixture is subsequently continuously removed in a proportioned manner. For this purpose, a mixer, metering feed means positioned upstream of the mixer and a continuously proportioning removal device positioned downstream of the mixer are provided. In order to ensure a troublefree addition and an accurately proportioned removal, the individual mixing components are in each case successively supplied in timed continuous manner to the mixing process, accompanied by the weighing of the total mixing material. During the feed pauses, the mixture is gravimetrically controlled and during addition is removed in volumetrically controlled manner.
