I. SJ-25 Single Screw Extruder Configuration:  

1) Screw Diameter: 25mm

2) Length-to-Diameter Ratio: L/D=28:1

3) Screw Speed Range: 120 rpm

4) The single screw main unit uses an AC 2.2KW motor with variable frequency speed control

5) Reducer: Gears and shaft parts are made of high-strength alloy steel material. Gears (shafts) undergo processes such as carburizing, quenching, and gear grinding. Gear accuracy is GB10095-88, grade 6, with gear surface hardness of HRC56-62°.

6) The single screw barrel is made of 38CrMoAlA nitrided steel, fully nitrided to 0.4~0.5mm. The barrel uses a special air-cooling device and is heated in three sections with stainless steel resistance heaters. The barrel temperature control instrument is digital and intelligent, ensuring accurate temperature measurement and control.

7) The screw is made of 38CrMoAlA nitrided steel, fully nitrided to a layer of 0.4~0.5mm, providing sufficient thrust for materials without decomposition.

8) Electrical Control System

a) Main electrical control components are Chint products

b) Control buttons are Chint products

c) Heating is controlled by the temperature controller via solid-state relays, using high-temperature resistant wires

d) The electrical control cabinet controls include: temperature control system, drive system, interlock and linkage system

II) Auxiliary System

1) Manual plate-type screen changer, easy to change screens

2) Water-cooled strand die head, including die plates, cast aluminum heaters

5. Pelletizing Auxiliary System
