30mm Twin Screw Side Feeder With PLC Control For Plastic Extrusion Compounding

30mm Twin Screw Side Feeder with PLC Control for Plastic Extrusion Compounding

This 30mm twin screw side feeder is universal side feeding auxiliary equipment for plastic extrusion compounding and petrochemical production. It adopts intermeshing co-rotating self-wiping segmented twin screws, all contact parts use stainless steel to avoid material contamination.
Equipped with independent PLC control system, the machine adjusts screw rotating speed from 0 to 100rpm freely. It stably transport talcum powder, calcium carbonate, short/long glass fiber and all inorganic fillers, maximum feeding capacity hits 500kg/h for glass fiber and 550kg/h for calcium carbonate powder.
The unit supports air cooling or water cooling, electric heating or steam heating mode, matches hydraulic and pneumatic pressure auxiliary system. Compact overall size 1000*500*1000mm, whole machine weight only 150kg, easy to move and install on different twin screw extruder production lines.

This side feeder realizes butt assembly with mainstream twin screw extruder series at home and abroad, including:
ZE, ZSE-MICRO, TSK, TM-W, MP65, TEX, TEK-HS, FED-MTS, NRII, TEM, LTE, TDS, MTE and domestic brands KEYA, LANTAI series extruders.

1. Wear-resistant integrated lining inside barrel

   The barrel installs one-piece wear-resistant lining, greatly reduce abrasion from hard mineral powder, extend equipment service cycle and cut maintenance frequency.

2. Intermeshing co-rotating segmented screw with multi-pitch design

   Different pitch screw segments combine freely. Materials convey evenly during operation, guarantee feeding precision: long glass fiber tolerance ±5%, short glass fiber tolerance ±2%. Stable and consistent feeding output avoids formula fluctuation.

3. User-friendly human-centered layout
   • Observation glass window to check internal material flow status anytime
   • Splined sleeve for quick disassembly
   • Flat screw head structure to reduce material residue
   • Height adjustable support stand to align different extruder heights
   • Leakage cleaning drawer collects scattered powder, simplify daily cleaning work
4. Customized service support

   Adjust heating, cooling, feeding volume and stand structure according to customers’ production raw materials, workshop space and extruder specifications.

1. Protect main extruder core parts and lower wear cost

   Fillers enter barrel from side position instead of main feeding port. Abrasive inorganic powder won’t directly rub the melting section screw and barrel of main machine, reduce spare parts replacement expenditure.

2. Gentle low-shear conveying protects filler integrity

   Low-shear twin screw conveying structure avoids excessive fiber breakage, keep original length of glass fiber, maintain mechanical strength of finished modified plastic products.

3. Lift overall production line throughput

   Side feeder bears all filler feeding work, main extruder focuses on melting and mixing, whole line runs at higher speed without material congestion, raise hourly output obviously.

4. Stabilize finished product quality

   Uniform feeding of fillers ensures full mixing with resin inside main barrel, raw material proportion stays stable, reduce defective products caused by uneven filler addition.

5. Cut comprehensive production cost

   Less wear loss of main extruder, fewer defective products, simple cleaning and maintenance all bring down long-term production running cost.
