Double Stage Volume Twin Screw Side Feeder for Parallel Twin Screw Extruder Precision Feeding

This two-stage volumetric side feeder matches all co-rotating twin screw extruders. It delivers stable, precise feeding for powder, fiber and inorganic filler materials.

The machine uses segmented self-wiping twin screws. Materials like talcum powder, glass fiber, calcium carbonate flow evenly without sticking or blocking. It fits petrochemical, plastic modification and composite material production lines.

1. SEW Motor: Provide adjustable stable driving power
2. Gearbox Assembly: Transfer torque to drive twin screws
3. Feeding Hopper: Store raw materials for continuous supply
4. Twin Screw Segments: Mix and quantitatively convey fillers
5. Twin Barrel Segments: Hold screw shafts, install internal cooling channels
6. Mobile Support Bracket: Fix the whole unit, adjust installation height

1. High precision low-noise self-developed gearbox

• Gear teeth get six-level precision grinding, carburizing hardening cuts running noise
• Resin sand casting + CNC machining keep gear dimensional accuracy
• Imported German bearings extend gearbox service life
• Spline sleeve connects gearbox and screw elements, quick disassembly for maintenance

2. Wear-resistant water-cooled alloy barrel Barrel body adopts wear-resistant alloy steel. Built-in water channels control barrel temperature during long-time feeding.
3. Self-wiping segmented twin screw design Split screw profiles wipe barrel inner walls automatically. No material residue accumulates inside the feeding channel.
4. Wide size range for flexible matching Rich specifications cover small lab extruders to large industrial production extruders. Support custom size based on production capacity demands.
5. Stable volumetric feeding performance Two-stage feeding structure controls material output accurately. Feed rate stays consistent for inorganic powder and fiber additives.

• Petrochemical raw material blending
• Plastic modification & masterbatch production
• Glass fiber reinforced plastic granulation
• Calcium carbonate / talcum powder filling extrusion
• All parallel twin screw extrusion production lines
