High Efficiency Double Screw Side Feeder for Twin Screw Extruder 25-95mm Main Extruder

316L stainless steel hopper twin screw degassing side feeder for wood powder fiber feeding

Product Overview

This reinforced twin screw extruder side feeder is specially designed for loose raw materials like mineral powder, fiber, wood powder and flake fillers. Ordinary side feeders easily clog when transporting air-rich powder, limiting feeding output. Our vacuum degassing side feeder integrates gas-solid separation technology to remove trapped air inside materials, eliminate feeding blockage, lift feeding efficiency by 30%, and stabilize the running of the main twin screw extruder.

All key wear parts are CNC precision machined with wear-resistant alloy steel, standard flange connection supports quick installation on 25–95mm twin screw extruders. Full PLC touch screen electric cabinet realizes adjustable feeding speed, real-time pressure monitoring and automatic vacuum degassing control, widely used in plastic modification, compounding, masterbatch production lines.

Technical Parameter

Main Components & Functions

1. SEW Motor: Stable driving power source, low noise and long service life
2. Gearbox Section: Precision transmission system, stable torque output for double screw rotation
3. 316L Stainless Steel Hopper: Large capacity feeding bin, anti-corrosion, easy cleaning
4. Double Screw Section (2 sets): Conjugate double helix structure, uniform mixing and conveying of fillers
5. Barrel Section (2 sets): Built-in cooling channel, hold screw shaft and melt materials
6. Mobile Support Bracket: Universal caster with brake, flexible position adjustment for production line
7. PLC Touch Screen Control Cabinet: Real-time parameter display, adjustable feeding speed, vacuum system linkage control

Unique Structural Advantages

1. Two-stage split cylinder design, built-in cooling channels to control material temperature and avoid thermal agglomeration of powder
2. Independent gas-solid separation cavity connected with vacuum extraction system + back-blow compression air pipeline, continuously remove air wrapped in loose materials
3. Conjugate double helix propulsion structure, no material dead angle, prevent fiber winding and powder bridging blockage
4. Integrated pressure gauge monitoring, real-time check internal conveying pressure to avoid material backflow
5. Mobile wheeled stand, easy disassembly, cleaning and maintenance without lifting equipment

Wide Application
