Unequal pitch spiral, variable diameter spiral, exhaust filter device, bag opening sealing device, weighing system, frequency conversion system, control backup system, etc.
Compression and feeding are carried out by unequal-distance and cone-shaped spirals, and the gas in the powder is physically squeezed by the differential speed of the two spirals. When the predetermined compression ratio is reached, the pressure valve opens and enters the feeding spiral, which is directly fed into the packaging by the pile-shaped feeding spiral. Inside the bag, the full density of material packaging is achieved.
Use the principle of physical extrusion and cooperate with the filter device to solve the gas in the powder.
Double screw feeding can control the gas in the powder to be discharged before entering the packaging bag.
PLC program control, man-machine interface operation, screw relative pressure monitoring, electronic scale weighing measurement.
Precipitated silica (white carbon black), matting powder, nano-light calcium carbonate, modified ultrafine talc, stabilizer, flame retardant, lubricant, various pigments, active modification and other powders.
