Gravimetric Control System for Powder

Brief Intro:

Gravimetric Control System for Powder will be installed on top of the extruder to measure and calculate the value of weight per meter and extrusion throughput and control the closed loop. The system will guarantee stable weight per meter and running per set values.



System Principle:

Applied with quick weighing technique with high precision and AI intelligent algorithm, the system continuously measure material consumption. Embeded control unit real-time acquire relative production details and screw rotary speed close loop with speed of haul-off unit. After setting values of weight per meter and extrusion throughput, the system will real-time to modify speed of both screw and haul-off unit to realize the control to wall thickness of pipes.

Applications:
Applications: Powder material with good flowability in continuous extrusion process such as plastics pipe, profile, film, sheets, cable industries ( typical application: CaCo3<20%)

Advantages:

GMSP-N Series 

  1.   Extrusion throughput and weight per meter control to remain product quality;

  2.   Shorten start-up time, save raw material, reduce the dependence on the operator’s skill or experience;

  3.   Raw material saved by 1-5% and production yield increased by 5%;

  4.   Continuous material save to enable 2 months investment return;

  5.   100% automatic control/dual control functions to control extruder and haul off simultaneously;

  6.   7”TFT touch screen display unit, dynamic display of control process;

  7.   Optimized structure of feeding port specialized for powder and spherular material with good flowability(typical application: <20% CaCo3);

  8.   Auto-compensation for the change caused by bulk density;

  9.   Quick release design for weigh bin;

  10.   Visual discharge outlet;

  11.   Auto filling control.

*Calculate based on special throughout and control status
