Import Dispersion Kneader — Buy in Bulk from Supplier in China

The Dispersion kneader from Dalian Jiaerxin Rubber & Plastics Machinery Co., Ltd. is an industrial mixing system designed for high-torque dispersion of rubber and thermoplastic compounds. It features a dual-rotor configuration with a nominal capacity of 150 to 300 liters, depending on material viscosity, and is driven by a variable-frequency motor with torque output exceeding 1500 Nm. The machine includes a closed mixing chamber with jacketed walls for precise temperature control, typically operating between 20°C and 250°C.

The rotors are constructed from hardened alloy steel with a surface hardness of HRC 58-62, designed to resist abrasion from filled elastomers and high-viscosity plastics. Standard internal clearance between rotors and chamber walls is 0.2 mm, a typical tolerance for industrial-grade dispersion kneaders. The machine supports both water and oil-based heating and cooling circuits, allowing compatibility with a range of compound types including natural rubber, SBR, EPDM, and PVC compounds.

This equipment is primarily purchased by tire manufacturers, automotive seal producers, and compounders supplying the construction and consumer goods sectors. Buyers typically require batch-to-batch consistency in compound rheology and minimal filler agglomeration. Trade terms are commonly FOB Dalian Port, with lead times ranging from 8 to 12 weeks after deposit. Packaging includes wooden crate with moisture barrier and steel strapping for ocean freight.

Dalian Jiaerxin Rubber & Plastics Machinery Co., Ltd. is a manufacturer based in Zhuanghe, Liaoning Province, with a registered address at No.810 Xinhua Road. The company is classified as an imported supplier with harbor-level trust verification, indicating compliance with export documentation standards. The listing does not specify years in operation, workforce size, or client names, and no certifications are confirmed in the source data.

The supplier focuses on the design and fabrication of rubber and plastic processing equipment, with dispersion kneaders as a core product line. There is no public information on R&D facilities, export history, or third-party audits. The absence of response rate and average response time suggests limited buyer interaction on the platform, but this does not reflect on the equipment’s technical capability. Buyers should request factory inspection reports and test videos before finalizing orders.
