Abstract
The system includes: a closed-type rubber kneader that kneads kneading materials that include raw rubber and carbon black; a rotation meter of a rotor; a power meter that measures the instantaneous power required to drive the rotation of the rotor; and a calculation device to which the measurement data is input. The calculation device calculates an evaluation index that evaluates the kneading efficiency of the kneader based on the total amount of shear calculated by integrating the shear velocity applied to the kneading materials by the rotor over the kneading time, and a unit work calculated by dividing the integrated power obtained by integrating the instantaneous power over the kneading time by the mass of the kneading materials.
