This JCD-B 50mm co-rotating twin screw extruder adopts a modular design principle, which can flexibly combine core components and control modes according to material properties and process requirements. It integrates versatility, universality and specialization, and is equipped with multi-channel vacuum exhaust, multi-type screen changing and pelletizing systems. The bimetallic wear-resistant barrel and advanced tri-axle transmission box ensure high-precision, high-wear resistance and high-output stable production, and is widely applicable to various plastic modification, compounding and masterbatch production processes.

The L/D ratio of the unit, combination form of barrel and screw, feeding method, screen changing & pelletizing method, and electrical automation control mode can be customized for material and process requirements, realizing the unification of versatility, universality and specialization.

Configurable with 1, 2 or multiple vacuum vents to maximize the removal of waste gas and volatile substances, effectively improving the purity of finished plastic products.

Various efficient screen changing methods to meet different filtration needs, including manual, automatic, hinged, single-station and multi-station types, adapting to different production efficiency and material impurity levels.

Optional pelletizing solutions for different application scenarios:

• Water-cooled strand pelletizing
• Air-cooled die-face hot cutting
• Water-ring die-face pelletizing
• Eccentric water mist pelletizing
• Underwater die-face pelletizing

Flexible barrel opening designs: top, bottom and side openings for easy maintenance and cleaning. Circulating cooling water channels ensure accurate and stable temperature control during processing. Barrel with bimetallic wear-resistant lining, featuring high wear resistance and high precision, meeting the quality requirements of high-end plastic processing.

Support multiple feeding forms to adapt to powders, granules, bulk materials and liquid additives:
