Abstract:
1. A kneading system with a closed-type rubber kneader, comprising: a closed-type rubber kneader that kneads kneading materials that include raw rubber and carbon black; a rotation meter that measures the rate of rotation of a rotor of the kneader; 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 of the rotation meter and the power meter are input, based on the input measurement data, data on the outer diameter of the rotor, data on the clearance between the position of the outer diameter of the rotor and the inner wall face of a chamber that contains the rotor, the calculation device calculating the total amount of shear by integrating the shear velocity applied to the kneading materials by the rotor over the kneading time, calculating a unit work by dividing the integrated power obtained by integrating the instantaneous power over the kneading time by the mass of the kneading materials, and based on the total amount of shear and the unit work, calculating an evaluation index that evaluates the kneading efficiency of the kneader.
