Qingdao Haixi anti-corrosion insulation equipment tells you: in order to improve the efficiency of the extruder feeding, the general use of mechanical auxiliary feeding, one of the commonly used auxiliary feeding way is screw feeding.

Spiral feeding

Spiral feed is suitable for raw materials that are not easy to bridge, and it is suitable for particle material crushing less than 12×12mm. The crushing of semi-plasticized extruded material is less than 25×25mm; Mass crushing < 25×25mm; The bulk density is greater than 300kg/m3; Water content less than 10%.

Stir feed
Agitate feeding suitable for crushing materials, such as clean woven bag filaments, film, etc. The powdering size of polypropylene woven bag is ≤40×40mm; Film pulverization size ≤40×40mm; XPS,EPS, pulverized size ≤30×30×30mm; Bulk density ≤150kg/m3; Moisture 5% or less; Applicable output: 250~500kg/h.
