50kg/h Laboratory Twin Screw Compound Extruder for Blue Plastic Granule Pelletizing

Lab double screw extruder l ,screw dia. 27mm for experiment and trial production output 50kg/h

Our twin screw extruders are widely applicable for various plastic processing, compounding and extrusion scenarios, covering the following fields:

• General Engineering Plastics Pelletizing: ABS, PC, POM, PP, PBT, PE, PA
• High-performance Special Engineering Plastics: PA6T, PA9T, LCP, PPS, PEEK
• Rubber & Plastic Blending Modification: PP, PE, PS+SBS, PA+EPDM, EVA+silicone rubber
• Polymer Alloy Blending: PC+ABS, PA+ABS, CPE+ABS, PP+EPDM, PA+SBS and other composite formulas
• Various Masterbatch Production: Color masterbatch, functional masterbatch, white masterbatch and black masterbatch
• Plastic Compounding & Modification: Filler compounding, fiber reinforcement and polymer performance upgrading
• Functional Film Extrusion Production: BOPP, BOPET, BOPI, BOPA, BOPS film, battery separator film, seawater desalination film and other precision film products

Equipped with high-torque transmission system, our extruders deliver 1 to 2 times higher output than conventional low-torque twin screw extruders of the same specification. The maximum throughput of our large-scale model can reach up to 12 tons per hour, ensuring efficient mass production.

Our compact high-efficiency models can replace larger-sized extruders from other brands under the same production capacity. For instance, the HPL51 extruder achieves higher output than ordinary 65-type extruders, effectively reducing equipment investment, material consumption, factory floor space and overall operating costs. Adopting heating rods instead of traditional cast copper heaters, the equipment saves 15%-20% of electric energy consumption.

Featuring ultra-high torque design, the gearbox load capacity reaches 15 Nm/cm³, ensuring strong driving force and stable operation. The maximum screw rotating speed can reach 1800 rpm, meeting high-speed and high-efficiency production requirements for various high-end materials.

The output shaft bearings adopt non-load-bearing structural design, which effectively avoids wear of vulnerable shaft bearings and greatly improves equipment stability. The professionally optimized gearbox achieves a designed service life of 72,000 hours (equivalent to 10 years of normal operation).

Supports a wide range of D/d ratio customization from 1.33 to 2.0. The screw gap can be precisely adjusted with a minimum clearance of 0.15 mm, meeting personalized processing requirements for different materials and production processes.

We are a professional manufacturer dedicated to the R&D, design and production of co-rotating and counter-rotating parallel twin-screw extruder production lines. Our equipment features high torque, high efficiency, low energy consumption, high cost performance and long service life, with a gearbox designed service life of 72,000 hours. Our manufacturing and technology level keep pace with the world’s top extruder manufacturers.

We provide a full range of products and technical services, including: complete twin screw extruder production lines, high-torque gearboxes, automatic LFT-D long fiber reinforced thermoplastic composite production lines, counter-rotating parallel twin screw extruders, differential concentration mixers. We also undertake large mechanical parts repair and precision machining, as well as customized design and processing of screw elements for German and Japanese brand extruders.
