SCM series volumetric dosers are suitable for auto - proportional mixing of new materials, regrinds, masterbatch or additives. A brushless DC motor is used in this series. According to the set mixing proportion, the microprocessor accurately controls rotation of the high precise dosing screw to squeeze out materials with an accuracy of ± 1%. A gear motor with gear ratio of 38: 1 or 75: 1 is coupled to a dosing screw of 12, 14 or 16mm diameter to give a total of six models with output. Ranging from 0.1 ~ 32kg / hr. Double color dosers can be assembled from two single color dosers if required.
