Single spiral valve port packaging machine technical parameters: 1, specification: the DCS-FJDA, the DCS-FJDB DCS-FJDC of packaging speed: 2 to 4 bags / min 3, measurement accuracy: ± 0.2% measurement range: 5 ~ 10kg 10 ~ 25kg 25 ~ 50kg 5, Pressure: 0 5 ~~ 0.7Mpa 6 Power Supply / Power: 380V 50Hz, applicable materials: all kinds of powder pellets, Bulk density from 0.5 to 1.5 T/m3,, such as flour, titanium dioxide, polyacrylamide, kaolin, talc, modified starch, PVC, PPVC, CPE, phthalic anhydride, etc.. Features: Single spiral valve port packaging machine representation models, such as titanium dioxide, xanthan gum, starch, dry mortar, polyacrylamide, kaolin widely used in industry. How it works: materials through pneumatic butterfly valve into the buffer silos, homogenized materials for exhaust, and then feed the inverter control valve pocket spiral sent to control the rotational speed of the spiral control feeding capacity bag once to said full sandwich bags by the control system to open the bag through the pneumatic bag chairs automatically turned to the conveyor belt away, in all the process, the system returns to the start position, re-homogenized material bagging.
