Gravimetric Doser (Powder)

Gravimetric Doser (Powder)

Suitable for automatic proportioning and mixing of new materials, secondary materials,
color master batches or additive materials;

Working principle:

Doser (powder) adopts twin screw metering and feeding, screw drive is directly driven by stepping motor, it is suitable for the accurate measurement of powder toner or fine grain sand,the gravity closed loop is established by screw speed and raw material weight in the hopper of the doser,it can compare the preset measurement value with the actual vakue in real time, through calculating the difference between these , constantlt fine-tuning the speed of the metering screw, achieve the purpose of accurate control of the master material quantity, the advantages of weightless metering can effectively avoid the color powder stacking density difference casused by the color powder uncertainly; Doser (powder) is eqquipped with forced mixing blade to prevent the bridge caused by poor fluidity of pigment, and the twin screw feeding has screw self-cleaning function. Doeser control adopts 7” color touch screen +PLC control mode,human-machine interaction is convenient ,interface straightforward and clear, and have communication interface preset which is convenient for data integration;
