Our factory supplies instruments: plastic refining machines, platen presses/hot presses, internal mixers, single-screw/twin-screw mixing and compounding extruder pelletizing machines, blown film machines/cast film machines/calenders/sheet extruders/profile extrusion lines/micro compounding spinning lines/3D consumable extrusion lines/pipe extrusion lines, etc.. Small-scale prototyping sold to universities, research institutions, and factory laboratories for application.

Usage batch size per formulation can be 1-3KG; continuous extrusion 8-10KG/H; used for material modification; reinforcement; filling; masterbatch, etc., for formulation use.

SHJ-20 Twin-Screw Compounding Extruder Parameters:

A、SHJ-20 twin-screw extruder aspect ratio 40:1; feeder 0.75KW;

1、 Gear reduction box

1）Reduction ratio: 3:1

2）Output shaft speed: 0~500rpm

3）Input shaft speed: Max 1500rpm

4）Main drive box integrates reduction and torque distribution, using a parallel three-shaft design, compact structure. Reduction, torque distribution, and radial bearings of the two output shafts all use NSK bearings.

2、 Main motor

1）Main motor: 4KW (AC motor)

2）Motor speed (MAX): 1500RPM

3、 Screw

1）Screw diameter: Φ21.7mm

2）L/D=40:1

3）Screw core shaft made of 40CrNiMoA material, threaded elements and core shaft connected by involute spline, high strength, high load capacity, easy disassembly and assembly.

4）Screw elements made of 38CrMoAlA nitrided steel, fully nitrided, surface hard chrome plated (roughness grade 10).

5）Overall hardness approx. HRC65~75.

4、Plastic extruder barrel

1）Barrel material uses premium 38CrMoAlA nitrided steel, fully nitrided, surface hard chrome plated (roughness grade 10). Hardness approx. HRC65-75, barrel length L=120mm/section;

2）One section is the feed barrel, three sections are reserved for auxiliary feed barrels, six sections are vent barrels, seven sections are extrusion barrels, the remaining sections are closed barrels.

3）Soft water circulation system

5、Heating (omitted) Uses melt temperature thermocouple specifically for measuring material melt temperature, uses pressure sensor specifically for measuring material pressure.

6、Vacuum degassing device
