device for dosage of granular, powdery or hogviskosa emnen

摘要

A device for the metering of plastic raw materials of granulate, or pulverulent, or highly viscous consistency in connection with plastic materials processing machines, where a rotating metering disc at the bottom of a drum-shaped receptacle discharges fixed amounts of material at a predetermined frequency, and where the semi-circular metering pockets on the periphery of the metering disc are wiped clean by a vertically extending radially and circumferentially flexible wiper finger which dislodges any material that might otherwise adhere to the pocket flanks at the point of gravity discharge of the plastic material from the metering pockets.
