Description
Working principle:
Doser adopts screw metering and feeding,screw drive is directly driven by stepping motor,suitable for the accurate measurement of granular masterbatch or sand,screw speed and raw material weight in the hopper of the doser to establish a gravity closed loop, can real-time measuring value which is preset ,compared with actual value, by computing the difference of both, constantly fine-turn metering screw speed, achieve the goal of feed rate under precisely controlled masterbatch, the advantages of gravimetric metering ,can effectively avoid the color masterbatch particle size difference(stacking density differences)and caused color masterbatch feeding is uncertainty;
Doser controller adopts 7”colorful touch screen+PLC control mode, human-machine interaction is convenient ,straightforward and clear, and have thecommunication interface preset,it is convenient for data integration；
The output of the doser can be configured with a wide range of output which can cover tens of g/h to 350KG/h.
