Description:
Conical twin screw extruder is professional equipment to extrude
PVC/ composite mixture of PVC and wood/composite pellets of PP/PE
and wood. Equipped with different die head, downstream equipment,
it can be applied for manufacturing of pipe, profile, composite
profile, panel, sheet and pelletizing, etc.. It consists of
following items:
- Driving motor: equipped with famous brand motor as driving source
- Gearbox: equipped with famous brand gearbox to ensure the maximum
output of power
- Screw & barrel: it is made of bi-metallic. The screw core is
equipped with device of temperature regulation of oil as medium and
barrel is equipped with air blower as cooling device. The designing
of screw and barrel will adapt the reasonable and optimal structure
based on the characteristics of the formula of raw material ensure
to get the plasticizing and melt stream for plastics.
- Control system: equipped with famous brand electrical components
ensure to get the accurate control.
