Plastic Recycle Pellets Granulation Machine Screw Barrel

As a core component of the plastic recycle pellets granulation extrusion machine, the pelletizing screw barrel plays a key role in recycling and pelletizing. It affects how effective pellet recycling is and how much it costs. We’re a 20-year-old pelletizing screw barrel manufacturer. Our pelletizing screw barrels are more wear-resistant, last longer, have better plasticizing properties, and produce more pellets. Our company has also successfully exported and supplied screw barrels to customers worldwide.

Plastic recycle pellets granulation machine screw barrel

1. For the waste plastic pelletizer screw barrel, we use 38CrMoAlA because it is less sensitive to heat deformation, wear-resistant, and corrosion-resistant.

2. It is machined with high precision to prevent material accumulation.

3. It is necessary to apply anti-wear treatment solutions at high levels for plastic recycling pelletizing materials with many impurities. Screw and barrel nitriding, layer depth of 0.7 mm, hardness of 1000-1100HV. The hardness of the thread working surface and overall screw stress resistance is not more than grade 2.

4. High wear resistance. To improve the overall screw barrel wear resistance, we optimize the screw barrel structure and provide wear-resistant treatment to improve the overall plastic recycling pelletizing screw barrel friction. Bimetallic alloy screw barrels, grooved feeding barrel are available for higher pelletizing requirements, providing enhanced service life.

5. The pelletizing screw barrel is structurally optimised for enhanced plasticization and higher output. For wet material and venting requirements, vented screw barrels are available.

Application

Recycle granulation machine single screw barrel

1. for PP, PE, ABS, PS, PC, PMMA, PVC, and other rigid materials.

2. for PA6, PA66 airbag fabric, fishing grid fabric, cloth, PP nonwoven fabric, and other soft materials.

3. Side feeding type wet granulation machine, for soft materials such as PP PE film, nonwoven bags, etc.

4. Wet granulation machine for PE, PP, PA, film, waste plastic fibres, nonwoven bags, etc.

5. Wet material drying granulation machine, for film, nonwoven bags, etc.

Recycle granulation machine parallel twin screw barrel

Granulation machine parallel twin screw barrels are designed for recycling different types of waste plastic. During extrusion, the screw barrel structure with vent port is primarily designed to discharge water and volatile gases, which facilitates stable pellet quality. It is mainly used to make pellets from PE and PP films.

PVC compounding machine twin screw barrels (conical type and parallel type)

The conical twin screw and parallel twin screw have the advantages of high output, effective plasticization and low energy costs. It is suitable for the preparation of compound granules for PVC pipes, profiles, sheets, foam boards, resin tiles, siding panels, WPC and other products.

Waste plastic chips, or particles granulation machine screw barrel

Specially designed for extruding waste plastic chips or particles. The extruders are available with vented screw barrels. Main applications include the preparation of PET chips, PC, PP, PE hollow-space panels, PE aluminum composite panels, and ABS composite sanitary panels.
