Import Dispersion Mixer — Buy in Bulk from Supplier in China

The dispersion mixer from China Dalian Second Rubber & Plastics Machinery Co., Ltd. is a closed-system kneading unit designed for rubber and plastic compound processing under controlled pressure and temperature. It features a hermetic sealing mechanism, variable speed drive, and temperature regulation up to 200°C, with a standard batch capacity of 10 to 150 liters depending on model. The machine is built with hardened alloy steel rotors and a cooling jacket integrated into the mixing chamber to maintain material integrity during high-shear processing.

Typical rotor configurations include Σ-blades with a 1.5:1 speed ratio, and the machine supports standard material compatibility with EPDM, NR, SBR, and PVC compounds. The internal surface finish is polished to Ra ≤ 0.8 μm to prevent contamination and ease cleaning between color changes. Standard models comply with GB/T 18452-2001 for rubber mixing equipment, and the electrical control system includes PLC-based automation with data logging for process consistency.

This equipment is purchased by medium to large rubber compounders in automotive, tire, and industrial sealant manufacturing, primarily for batch preparation before extrusion or calendering. Buyers typically order units with optional pneumatic lid lifting, solvent recovery systems, and integrated dust extraction. Trade terms are commonly FOB Dalian Port, with lead times of 60 to 90 days after deposit. Packaging includes wooden crate with moisture barrier and steel strapping for ocean shipment.

China Dalian Second Rubber & Plastics Machinery Co., Ltd. was established in 1972 and operates from a 150,000 square meter facility in Ganjingzi District, Dalian.
