SGD-EB series dosers are suitable for auto-proportional mixing of virgin materials, regrinds, masterbatch or additives. The motor with gear ratio of 38:1 is coupled to a dosing screw of 12, 16, 20 or 30 mm in diameter to give a total of four models with the output ranging from 0.04-60kg/hr . Double color dosers can be assembled from two single color dosers according to customer’s requirement. SGD-EB supports the extruder mode. When working with the extruder, it only requires simple circuit adjustment that can achieve the linkage between the masterbatch metering and the rotating speed of extruder screw, so as to maintain stable additives proportion. Due to small additives proportion and dosage, SGD-EB can work with the Venturi Loader VL to realize auto feeding of the masterbatch.
