Product Description The Principle of extrusion unitThe basic working principle of extrusion unit :Make the Polymer melt (or viscous fluid) through a certain shape of the die ,Under the pressure of screw ,become the continuous profiles with constant cross section shape. Various die heads are available for specific measuring tasks. The screw with different diameter, length-diameter radio and compress ratio can be chosen depending on the tested materials. It can complete different functional simulation test in laboratory environment with the die heads and other auxiliary equipment.Conical Twin-screw Extruder Platform:Laboratory Conical Twin-screw Extruder can be integrated by main unit and conical twin-screw extrusion unit. That can be used to simulate real production process in the laboratory.Because of its special structure, the residual material can be cleaned quickly. In the measuring extrusion unit, the sample material begin plastify under practice-oriented conditions and extruded through the die head.Matched well with different die heads ,it's used for extruding the Belt, Tube, PCPO and granulation .Conical 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 the 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 compositionDrive deviceIt 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 deviceConical 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. BarrelTwo threaded bores opposite each other are provided at the end of the barrel of each measuring extruder for taking a thermocouple and a pressure transducer for measuring the temperature and the pressure of the melt in front of the die channel.ScrewBecause 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. DieMounting 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 PVC pipe, plate, sheet, film, profile, and granulator etc. Machine specification in details Movable Main PlatformPhotographPerformance IndexPerformance Parameter Control ModeIndustry BusPower supply3×380V,60Hz +N +PEDocking modeManual lockFixing ModeMovablePower of Motor11.0 kWMotor Speed1500 r/minReducer Rate1:10Speed Range0.1 ~150 r/minRated Torque0 ~ 700 NmSpeed Accuracy0 .05% F.STorque measuring methodCantileverTorque Range0 ~ 900 NmTorque Accuracy0.1% F.SStatic Measurement Accuracy of Temp0.1oCDynamic Measurement Accuracy of Temp+ 0.5oCMelt pressure Range0.1 ~ 30 MPaMelt pressure Accuracy0.5% F.SPC operating SystemWindow 10Application SoftwareHapro Control software Mixer report software Extruder report softwareViscosity softwareWeight Dimension (L×W×H)1050×750×1360 mm Center height1000mm (2) Conical Twin Screw Extruder PhotographPerformance IndexPerformance Parameter Screw cylinder combinationPneumatic Pull and pushAs shown in the left picture, the barrel is separated, and it is convenient to clean the screw by pushing and pulling to open and closeScrew Diameterlittle -end:35 mmBig-end:81mmScrew material: SKD61 ,Screw edge surfacing alloyBarrel material :Main part 38CrMoAlA,inside inlaid with a full hard alloy sleeveHardness: HV900~1100Brittleness: ≤2Thickness of nitriding layer:0.5~0.8mmScrew arris length865mmTemp control systemRKC from JapanTemp sensorJ type thermocoupleHeatingElectrical Heating/8 Zones(Barrel 4,Die head 4)Barrel heating power9 kWDie head heating power4.2 kWMax.
