PURPOSE:To feed a discharged material to a post process as it is without measuring the Mooney viscosity of the material by controlling mastication so as to discharge a masticated material having desired Mooney viscosity when the data base related to the viscosity of a rubber material is preliminarily formed to set and input Mooney viscosity. CONSTITUTION:In a front process, the shearing stress tau1 of a rubber material, the shearing speed gamma1 of a kneader and the function tau1=f(gamma1, T) of the temp. of the material are preliminarily determined and the shearing speed tauML of the material with Mooney viscosity ML is represented by function tauML=g(tauML, gammag) (wherein y is the shearing speed of the kneader). Next, gammag and Mooney viscosity ML to be obtained are substituted for this function formula to calculate the shearing speed tauML of a material having desired Mooney viscosity. Next, gammag is substituted for gamma1 of the function formula determined in the front process and, if tau1=tauML is formed, the temp. TML of the material having desired Mooney viscosity is calculated. Next, the temp. of a material during mastication is measured within a real time and, when temp. reaches TML or higher, the masticated material is discharged. |
