Laboratory Parallel Co-Rotating Twin Screw Extruder with Torque Measurement

Product Description

Parallel twin screw extrusion unit (co-rotating), widely used in rubber and engineering resin blends, dispersion, modification, enhancement, chlorinated polypropylene and high water absorbing resin devolatilization, Biodegradable master batch,polycondensation of polyamide, polyurethane addition polymerization reaction extrusion; carbon powder, magnetic powder pelletizing; cable insulation material, sheath material,low smoke and low halogen flame retardant PVC cable and all kinds of silane cross-linking material preparation, etc. Dedicated to the extrusion forming process, for example the pelletizing experiment. Parallel Twin-screw platform is consist of the Drive device, Feeding device, Barrel ,Twin-screw and Dies parts, etc. The Twin-screw is the heart of the extruder, divided into the charging section (solid conveying zone), compression section(melting zone) and the homogenization section (the melt conveying zone) three parts. Put the material into the hopper ,under the action of a rotating screw, material was pushed on to direction of the nose. Material endures strong shear, mixing and calendaring in the barrel, In this process, Meanwhile, the physical states of material the evolve from glass state to the high elastic state ,eventually become sticky flow pattern .
Equipment composition Parallel Twin-screw platform adopts screw metering feeding device.According to the properties of material production and processing technology conditions, adjust the volume of feed speed and extrusion in order to achieve the balance.
Drive device
It is mainly used to complete the plastic plasticizing and transportation by uniform rotation for torque setting, Servo motor control screw torque, pre-set torque from touch-screen.
Feeding device
Barrel and Screw
Barrel contains materials and screw. The twin-screw is the heart of the extruder, divided into the charging section (solid conveying zone), compression section(melting zone) and the homogenization section (the melt conveying zone) three parts. Put the material into the hopper ,under the action of a rotating screw, material was pushed on to direction of the nose. Material endures strong shear, mixing and calendaring in the barrel, In this process, Meanwhile, the physical states of material the evolve from glass state to the high elastic state ,eventually become sticky flow pattern .Because of its rotation, the powder or particle shape plastic was pushed to the former, so as to achieve compaction, melting and mixing purpose of homogenization,
Dies
Mounting and interchanging of the die heads at the extruder is very easy: just fix them with the ring nut at the extruder barrel. The die heads are made of extremely corrosion-resistant steel and are heated electrically in the standard version ,and can be disassembled for cleaning. Various die heads are available for specific measuring tasks.For example ,It is mainly used in extruding and forming plate, sheet, film, profile, and granulator etc.
