CWJ45 Twin Screw Side Feeder | 3KW D2 Steel Side Feeder for KY52 Twin Screw Extruder Granulation

CWJ45 twin screw side feeder is compact auxiliary feeding equipment customized to match KY52 twin screw extruders. It adopts twin segmented self-wiping screws made of D2 alloy steel. The unit stably conveys glass fiber, talcum powder, calcium carbonate and various inorganic fillers during plastic granulation.

The whole machine features adjustable stand height and mobile casters for flexible field layout. It delivers stable 100kg/h feeding output under 300rpm screw speed, protecting the main extruder barrel and screw from severe abrasion.

1. Drive Motor: Supply stable power to drive twin screw rotation
2. Gearbox Assembly: Transfer torque, keep uniform screw operation speed
3. Feeding Hopper: Store bulk powder and fiber raw materials for continuous supply
4. Twin Screw Segments: Mix and push fillers evenly, self-clean barrel inner walls
5. Split Barrel Segments: Fix screw shafts, contain materials during conveying
6. Height Adjustable Mobile Bracket: Support the whole feeder, adjust height to align main extruder, move freely via casters

1. Reduce wear loss of main extruder core parts

   Feed fillers from the side instead of the main feeding port. Abrasive inorganic materials avoid direct friction with the main extruder melting section screw and barrel, extend main machine service life and cut replacement cost.

2. Gentle low-shear conveying for fragile fillers

   The twin screw structure delivers materials with mild shear force. Short glass fiber keeps complete length without excessive breakage, guarantee finished composite material mechanical performance.

3. Boost overall production throughput

   Separate side feeding shares the main extruder feeding burden. The main machine runs at higher speed without material blockage, lifting whole line hourly output.

4. Stabilize finished product quality

   Fillers get uniform mixing before entering the main barrel. Raw material proportion stays consistent, reduce product deviation and defective rate.

5. Compact space-saving design

   Small overall size fits narrow production workshops. Adjustable stand and rolling casters simplify installation, disassembly and position shifting.

6. Wear-resistant D2 steel screw for long service life

   D2 alloy steel screw holds strong anti-abrasion performance, suitable for long-time continuous transportation of hard mineral powder.
