China Professional Triple Screw Extruder Manufacturer — Granuwel

Granuwel has designed a series of high-efficiency three-screw extruders. These machines are equipped with a three screw design that provides an optimized balance between plasticizing effect, output and energy consumption.

GSE Series Triple Screw Extruder


The triple screw extruder has a flexible and diverse geometric arrangement. Many meshing zones form multiple changes in the flow direction and flow rate of the material, and the distribution of particles in space has a very beneficial effect, with excellent mixing characteristics, small aspect ratio, high production capacity ratio has attracted much attention.

The structure of the triple screw extruder is characterized in that the three screws are arranged in a line and rotate in the same direction, which is equivalent to the production capacity of two pairs of twin-screw three-screw extruders.

GSE Series Triple Screw Extruder advantages:

1. The triple screw extruder with sufficient melting, dispersing and evenly arranged in a line increase the compounding range, improve the effect of compounding, and have a good actual effect of plasticizing. Because of the existence of the two meshing areas, the rolling range becomes Multipliers make the dispersion more even.

2. High production capacity.
Taking the production of talc powder high-filling masterbatch as an example, without high stirring, the 3-Φ52 machine can produce a filling masterbatch with a high concentration of 80% at one time, and the production capacity is 350 kg/hour , and 2-Φ52 (same type of twin-screw machine) can only produce 40% concentration of filling masterbatch without relying on high mixing or repeated processing, 60 kg/hour.

3. Energy saving.
Taking the 3-Φ52 machine as an example, the main motor of 75kw, 500 rpm, produces 50% concentration of carbon black masterbatch, 180kg/hr, the main motor current is 90 amperes, and the specific power is only 0.2-0.25kw.

4. The products are of high quality.
One is that the twin-screw extruder produces 50% concentration of conductive carbon black masterbatch, which requires internal mixing, while the three-screw extruder does not require an internal mixer, and the material can be directly fed into the three-screw extruder to produce 50% concentration of carbon black masterbatch, bite the masterbatch will be deflated, cracked but not broken, indicating that the manufactured masterbatch has good toughness. why? It is because of its sufficient melting and uniform dispersion of components. It is used to blow 0.005mm film, and the test results are particularly well-proportioned. If relying on high stirring, the three-screw extruder can produce a higher concentration of carbon black masterbatch, and the particle toughness is good.
The second is the 85% calcium carbonate filled PE or PP masterbatch produced by the twin-screw machine, which will be broken when pinched with a finger, while the masterbatch of the same preparation produced by the three-screw machine cannot be pinched with the fingers, and the centrifugal The dehydrator is dehydrated and dried without breaking it.
The third is to produce PP flame retardant cable material. After banburying, the material is made by a 2-Φ65 twin-screw extruder with an aspect ratio of 40. The strength is 13Mpa and the elongation rate is 185%. However, using a 3-Φ65 three-screw machine without internal mixing, the strength of the material produced is 14Mpa and the elongation is 237%. In addition, the three-screw machine can process aluminum powder or masterbatch with an antimony trioxide filling of 70%, but the twin-screw machine cannot.

Wide application experience

Biodegradable plastic is a plastic that is degradable by natural microorganisms like bacteria, fungi and algae. An ideal biodegradable plastic is a polymeric material that performs well, can be fully decomposed by microorganisms after disposal, and ultimately becomes a component of the carbon cycle in nature through inorganization.

Color masterbatch is an integral part of the plastics industry. Not only can it give color to plastic products, increase the value of goods, enhance certain performance of plastics, but also can give particular optical properties to materials.

Started in the 1940s, the new functional polymers, which primarily include all kinds of engineering plastics (such as PA, PC, ABS, PET, PPS, etc.), are already used in electronics, electrical appliances, automotive, transportation, aviation, defense and military industries, etc.

Filler masterbatch is available for processing plastic films, garbage bags, shopping bags, undershirt bags, packaging bags, etc. It has excellent dispersion, blown film without white and black spots, and high fineness to ensure the luster and toughness of the product.

Non-crystallization dry PET sheet extrusion offers several advantages. It is used to produce PET/PLA sheet without the energy consumption of pre-drying crystallization and adapting to the production of materials with high output, low energy consumption and high plastic quality.

The PET waste plastic bottle cleaning line means that the waste plastic bottles are de-labeled by the de-labeling machine, pulverized by the crusher, and then processed by cleaning and drying equipment, so that the recycling and integration of waste plastic bottles becomes a new type.

Thermoplastic Elastomer has extensive adjustable hardness and physical properties. Also, it doesn’t need to be vulcanized, is recyclable, and can reduce costs, so the application areas are relatively wide including seals, automobile interiors, adhesive coated materials, various pipe fittings, etc.
