2) Speed control system adopts Taiwan Delta inverter.
3) Screw design: single threaded screw structure. Speed reducer radio 11:1.
4) Motor and Reduction gearbox adopt tandem style. With horizontal mixer, Feeding body feeds smoothly.
5) Both feeding body and hopper are streamlining, blanking smoothly and clear conveniently.
SE-120 Single-screw Venting Extruder
1) Screw diameter:120mm
2) Length/Diameter ratio(L/D):28:1(Longer feeding port)
3) Screw revolving speed:30~120rpm
4) Motor: 75KW AC Motor(Siemens Beide brand), using Taiwan Delta inverter;
5) Reduction gearbox:Gear and axial parts using high quality high-speed tool steel, getting through carburizing, quenching and grinding process, etc. Gear accuracy is GB10095-88, 6 class, Hard teeth surface is HRC56-62.
6) The barrel is made of 38CrMoAlA nitrogen treatment. Nitration case depth:0.4~0.5mm. The barrel uses Stainless steel electric resistance heating with six section heating separately. The temperature control meter of the barrel is the Japan Ormon product with intelligent temperature control in each zone.
7) The screw is made of 38CrMoAlA nitrogen treatment. Nitration case depth:0.4~0.5mm. To ensure that material have enough thrust and materials do not break down.
8) Barrel uses Fan cooling
9) Hydraulic plate larger screen changer device (filter system) with Cast Aluminum changer heater.
