Twin Screw Extruder Side Feeder For Fiberglass Calcium Carbonate Filling
The twin screw extruder side feeder is professional auxiliary feeding equipment matched with co-rotating twin screw extruders, specially optimized for continuous quantitative delivery of long fiberglass, calcium carbonate powder, talc, mica and other mineral fillers. Different from main feeding hopper on extruder head, this side feeder installs on the side barrel of twin screw extruder, adding fillers in the middle melting zone to avoid glass fiber breakage and powder pre-carbonization during high-temperature melting.
Equipped with double alloy feeding screw, anti-bridging stirring hopper, frequency conversion speed regulation motor and height-adjustable mobile trolley with casters, the machine realizes stable, uniform and adjustable feeding of fiberglass and calcium carbonate. The feeding barrel adopts wear-resistant alloy steel, inner bore precision grinding, effectively resist abrasion from hard mineral powder. Widely matched with TEX, STS, ZSE series twin screw extruders for glass fiber reinforced plastic, high-filler calcium carbonate masterbatch, flame retardant modified plastic and WPC composite production lines.

- Protect Long Fiberglass From Excessive Shear Breakage
Side feeding in the middle melting zone avoids long glass fiber entering high-shear initial melting section, retain fiber length to guarantee finished plastic tensile strength and impact resistance, solving brittle product defects caused by fiber crushing. - Eliminate Calcium Carbonate Bridging & Arching Blockage
Built-in stirring blade inside hopper continuously agitates calcium carbonate fine powder, prevent static adhesion and arch bridging, realize continuous stable powder delivery without frequent manual cleaning. - Uniform Quantitative Feeding With Small Output Deviation
Twin parallel screw self-stirring conveying structure ensures even mixing of fiber and powder before entering extruder, feeding error controlled within ±2%, stable filler proportion to guarantee consistent plastic material performance batch by batch. - Wear-Resistant Alloy Barrel Adapt To High Mineral Filler
Alloy feeding barrel with optional bimetallic liner resists abrasion of hard calcium carbonate and talc powder, extend service life and reduce replacement frequency compared with ordinary carbon steel feeders. - Flexible Mobile Design For Multi-Production Line Switch
Brake casters + height adjustable stand allow quick disassembly and movement between different twin screw extruders, fast flange docking without complicated equipment reconstruction, save production line conversion time. - Avoid Powder Carbonization & Black Spot Defects
Calcium carbonate fed in middle section will not stay in high-temperature front barrel for long time, effectively prevent powder thermal decomposition, reduce black speck and yellowing defects of finished pellets.

Q1: What materials is this twin screw side feeder suitable for?
A: Mainly for long fiberglass, calcium carbonate powder, talc, mica and other mineral fillers, it can feed fiber and powder separately or mixed at stable ratio for plastic modification.
Q2: Why feed fiberglass via side feeder instead of main feeding hopper?
A: Side feeding adds glass fiber after partial plastic melting, greatly reduce screw shear force on fiber, keep complete fiber length to improve finished plastic mechanical strength.
Q3: How does the feeder solve calcium carbonate powder blockage?
A: Equipped with built-in anti-bridging stirring blade inside the hopper, continuously break powder arching to realize smooth continuous conveying without shutdown cleaning.
Q4: Is this side feeder compatible with JSW TEX twin screw extruder?
A: Yes, the outlet flange double 8-shaped inner bore matches TEX54, TEX65 and other mainstream models, direct docking without barrel modification.
Q5: Can I adjust the feeding amount of fiberglass and calcium carbonate freely?
A: Adopt frequency conversion stepless speed regulation, the feeding capacity can be adjusted at will according to the filler proportion formula requirements, output fluctuation less than ±2%.
