Download Inquiry Buy Now
SGB series gravimetric blender can be used in the fields of injection moulding machines, blow moulding machines and extrusion lines for proportionally precise mixing of several types of material. This series machines adopt Becca levy PLC controller and latest ingredients calculation methods. The machine is controlled by an advanced microprocessor with a digital display that is simple to calibrate. The self-compensation and calibration function ensure accurate material dosing percentages. A high precision electronic weighing scale is used to ensure precise weighing of every batch and ensure accuracy to ±0.1%~0.3%. There are 8 models available to be selected based on various materials and throughputs. (This series are not suitable for powder and sheet pieces weighing)

SGB Feature

  • The microscale metering accuracy is +0.1% when all materials are blended through gravity
  • Auto calibration function which is performed every time after material weighting ensures best propor- tioning accuracy
  • Up to 100 groups of recipes can be saved
  • Have alarm history record function
  • SGB-600 and models below are directly mounted on machine
  • For SGB-1200 and models above, floor stand (equipped with floor stand, material storage tank and pneumatic discharge valve)
  • Adopt Ethernet communication function to realize online centrally monitor function
  • Equipped with automatic suction control function, and vacuum generator SVG and central hopper receiver SHR-U-ST are optional.

Working Principle

When the machine start working, hopper 1 starts dosing on the basic calculation of set weight and unit time feeding of metering valve. The valve will closed after feeding time and then load cell will start work. Within the Precision range, the machine will go to hopper 2, and then in succession hopper 3, until all the hopper finishing dosing. After dosing material will fall into  the mixing tank and be blended until reaching the time limit. Manually open the shut - off plates or automatically open the pneumatic discharge the valve to let the material fall into the injection molding machine or storage tank.
