Conical double-screw extruder

Short Description:

Conical twin-screw extruder is a kind of high efficiency mix extruding machine. The features of such extruder are as follows: low shearing speed, material difficult to decompose, mix evenly, stable quality, high capacity, wide application and long service life, etc. If work with proper screw and auxiliaries, it can directly extrude thermoplastic plastics, especially rigid PVC powder into pipe, board, sheet, film or profile, etc. It also can be used for plastic modification and powder granulation. 


Product Detail

Conical twin-screw extruder is a kind of high efficiency mix extruding machine. The features of such extruder are as follows: low shearing speed, material difficult to decompose, mix evenly, stable quality, high capacity, wide application and long service life, etc. If work with proper screw and auxiliaries, it can directly extrude thermoplastic plastics, especially rigid PVC powder into pipe, board, sheet, film or profile, etc. It also can be used for plastic modification and powder granulation.

The extruder is fixed with fault protection, overload alarm, screw core constant temperature oil circulation system, barrel oil cooling system, vacuum exhaust pipe and ration feeding device.

There are many kinds of electric control system for selection (for example: PLC auto control system). It is driven by DC motor. Through inverter or DC speed regulator it can achieve stable stepless speed adjustment, high precision and energy saving. Intelligent dual display digital temperature controller is used to improve control precision and temperature fluctuation.

Conical twin-screw extruder series conical twin screw extruder is mainly composed of barrel screw, gear transmission system, quantitative feeding, vacuum exhaust, heating, cooling and electrical control components Etc. The conical twin screw extruder is suitable for producing PVC products from mixed powder.

It is special equipment for PVC powder or WPC powder extrusion. It has advantages of good compounding, large output, stable running, long service life. With different mould and downstream equipment, it can produce PVC pipes, PVC ceilings, PVC window profiles, PVC sheet, WPC decking, PVC granules and so on.

Different quantities of screws, double screw extruder have two screws, sigle screw extruder only have one screw, They are used for different materials, double screw extruder usually used for hard PVC, single screw used for PP/PE. Double screw extruder can produce PVC pipes, profiles and PVC granules. And single extruder can produce PP/PE pipes and granules.

The extruder is widely used in following areas:

Suitable for PVC, UPVC powder

Process pipe, plate, sheet, profile as well as granules
