CWJ70 Twin Screw Side Feeder | Alloy Steel Side Feeding Machine for 70/75 Twin Screw Extruder
CWJ70 twin screw side feeder is a matched auxiliary feeding device for 70 and 75 series co-rotating twin screw extruders. It uses self-wiping segmented twin screws to deliver stable quantitative feeding of various fillers.
It handles short glass fiber, talcum powder and all kinds of inorganic powder raw materials. The whole machine uses wear-resistant alloy metal materials, supports long continuous production runs, and keeps feeding output steady without material blockage or residue.

- SEW Motor: Output stable adjustable power to drive twin screws
- Precision Gearbox: Transfer torque, adjust screw rotation speed steadily
- 316L Stainless Steel Hopper: Store raw materials, avoid powder corrosion
- Twin Screw Segments: Mix and push fillers evenly, self-wipe inner barrel wall
- Alloy Steel Barrel: Fix screw shafts, hold materials during feeding process
- Adjustable Support Bracket: Stabilize whole feeder, adjust height to align extruder
-
Durable long-life gearbox unit
We independently design and manufacture all gearboxes. Gear teeth pass six-level precision grinding and carburizing hardening treatment. Resin sand casting and CNC machining lock high dimensional accuracy. Imported German bearings reduce operation noise and extend service life. Spline sleeve structure lets you separate gearbox and screws quickly for maintenance.
-
High wear-resistant metal core parts
Barrel uses alloy steel. Screws adopt Cr12MoV anti-abrasion material. Drive shaft uses WR12 wear-resistant steel. Hopper selects 316 stainless steel, resists acid and powder corrosion, fits long-term powder feeding work.
-
Self-cleaning twin screw conveying design
Segmented self-wiping screw profiles scrape residual materials off barrel inner walls. No material buildup inside the barrel, cut cleaning time between different material batches.
-
Stable output for multiple inorganic raw materials
It adapts coarse fiber and ultra-fine talcum powder. Different materials keep fixed feeding volume, guarantee consistent formula ratio during plastic compounding production.
-
Perfect compatibility with 70/75 twin screw extruders
All flange sizes, center distance and L/D parameters match 70 and 75 series twin screw extruders directly. Height-adjustable bracket and movable casters support fast installation and position adjustment.
- Glass fiber reinforced plastic granulation
- Talcum powder filled plastic modification
- Inorganic filler masterbatch production
- 70/75 parallel twin screw extruder auxiliary feeding
- Petrochemical composite material blending
Q1: Which twin screw extruder models fit CWJ70 side feeder?
A1: It directly matches 70 and 75 series co-rotating twin screw extruders.
Q2: What material makes the feeding hopper of CWJ70 feeder?
A2: The hopper uses 316L stainless steel to resist powder corrosion.
