Continuous metering equipment, for delivery of textile and film chips and fibers to a twin screw extruder, comprises two stirrers above two pin-covered metering rolls with stripper plates at the base

摘要

Two intermeshing horizontal counter-rotating stirrers (2.1,2.2) are located in a storage container (1) and ensure central feeding of chip and fiber material without bridging to a pair of horizontal, counterrotating metering rolls (5). Constant output from the base of the storage container is achieved by constant weighing of material per unit time and speed control of the metering rolls. Two intermeshing horizontal counter-rotating stirrers are located in a storage container and ensure central feeding of the chip and fiber material without bridging to a pair of horizontal, counter-rotating metering rolls. Constant output from the base of the storage container is achieved by constant weighing of material per unit time and speed control of the metering rolls. Two opposing stripping plates at the base of the metering rolls remove material from the spaces between the rows of pins. Synthetic fibers handled by the machine include polyamide, polyacrylonitrile, polypropylene, polyethylene terephthalate and regenerated cellulose fibers.
