Intermeshing Mixers

KOBELCO’s intermeshing rotor provides better intake of the rubber and improved dispersion than intermeshing rotors currently available in the market. This superior performance is especially effective in high silica compounds. Our rotor also provides better uniformity in compound properties between batches.

We have established a solid track record in supplying intermeshing mixers worldwide, and have received high acclaim from our users.
