Lab twin screw extruder
1.Simple description:
SJSZ series conical twin screw extruder is a highly efficient agglomerating and
extruding equipment. Machines of this series feature low shearing rate, uneasy
degradation , even plastication and agglomeration, reliable quality ,wide
application range and long servicing life. Using PVC powder as raw material for a direct forming, the exturders perform an excellent effectiveness. These
machines have automatic temperature control,vacuum gas exhaustion, stepless speed regulation, as well as a forced feeding and self-cleaning mechanism.Machines of this series have wide application. With appropriate extruding heads,screws and other auxiliaries, they are able to directly convert plastics into pips,plates, bars, films, hollow cross-section products. SJZ Series Conical Twin Screw Extruder Super big torque gearbox New screw design
Dosing feeding or mixing & forcing feeding Reliable electrical control cabinet.
1. low consumption,
2. high quality screw and barrel (38CrMoAlA, nitriding), long service time.
3. with PLC control, full automatic, easy operation.
4. wide use, with different molds, different use.
5.specially design, with wheel, convenient to move.
