Melt extrusion pump to increase production

Extrusion output increases , generally when the pressure within the extruder is increased , the amount of counter-current flow increases and the drain , causing the entire flow rate. While advancing the screw drive material consumed power increases , the shear force is increased , the material temperature , resulting in degradation of the material , processing the heat-sensitive material is negative. When installing pressurized melt gear pump can play the role . As the melt gear pump can be completed regulator , booster function metering section of the extruder , the extruder screw and therefore only need to complete the continuous conveyor , melting temperature decreases , the effective increase in extrusion capacity , the power to reduce energy consumption , the reverse flow volume and leakage flow can be reduced , the screw may be performed at low speed rotation , the final result is a reduction of shear forces suffered by the material , the melting temperature decreases, the effective increase in the extrusion amount , the power consumption is reduced , increasing the product range manufactured . After such a melt extruder gear pump is installed , the output from 270kg / h to 450kg / h. Due to the lower melting temperature , the yield of LLDPE blown film is also improved , for example, installed in the melt is less than the yield of the gear pump equal to 180kg / h extruder , its output can reach 310kg / h.

In addition, as the Stainless steel melt pump with metering , booster function , which is installed on the melt extruder gear pump metering section of the screw can be shortened , mixed growth segment , increasing spiral groove depth.
