Conical Twin Screw Extruder

1.Characteristics of conical twin screw extruder:

Model SJZ series twin conical screws extruder is a kind of special equipment for
extruding of PVC powder. With different sorts of molds and auxiliary machines,
it can produce all sorts of PVC plastic pipe material, profiled material, plate
material, sliced material, bar material and granulation.

The screw has applied oil cooling system. Barrel is cooled by special wind
cooling system. The system has applied special computer control. According to
customer's requirements, most reasonable screw can be made so as to achieve best
plasticity state and material quality. The screw is made by high precision
special digital screw miller, extruding property can be highly harmonized. It
has firstly introduced advanced technique of producing screws with variable
pitch and depth, so that the material can be more softly sheared and cut. The
distribution box is specially designed, pull force bearing is fully imported,
the drive life span can be prolonged. It can bear larger extruding pressure. The
electrical system has mainly applied imported parts, it has multiple alarm
system, there are few problems which can be easily eliminated. The cooling
system has applied special design, heat emission area is enlarged, the cooling
is rapid, temperature control tolerance can be ±1°C.
