Import China Internal Mixer — Buy in Bulk from Supplier in China

The China Internal Mixer from China Dalian Second Rubber & Plastics Machinery Co., Ltd. is a heavy-duty machine designed for plasticating and mixing rubber or plastics. Available in 55L, 75L, and 110L chamber capacities, it features improved tangential and intermeshing rotor designs to meet diverse formulation and processing needs. The tangential rotor options include two-wing, four-wing, and six-wing structures, while the intermeshing rotor incorporates a width edge and involute meshing area to enhance rubber dispersion and cooling efficiency, ensuring consistent mixing quality.

Constructed for industrial rubber processing, the mixer handles compounds with varying viscosities and additivation requirements. The tangential rotor design is optimised for high shear and rapid material incorporation, while the intermeshing variant delivers uniform dispersion critical for high-performance rubber applications. Typical industry standards for such mixers include chamber pressures up to 10 MPa, rotor speeds of 20 to 60 RPM, and temperature control ranges of 50 to 200°C, depending on the material and process.

This equipment is primarily used by tyre manufacturers, rubber product producers, and compounding plants. It supports batch processing with cycle times typically ranging from 3 to 8 minutes per batch, depending on the formulation complexity. Buyers should confirm compatibility with their specific rubber grades, as well as the machine’s integration with downstream processing lines such as calenders or mills. The supplier’s long-standing presence in Dalian, Liaoning, positions it as a reliable source for rubber machinery with proven engineering expertise.
