The invention discloses an equipment production line for rubber plasticizing processing and a production technique thereof. A feed stage, a plasticizing stage, a rubber mixing stage, a refining stageand an aftertreatment stage are included. According to the equipment production line for rubber plasticizing processing and the production technique thereof, waste tires are subjected to plasticizingreproduction, therefore, the technical problem of environment pollution is solved, the waste tires become chunk rubber blocks after being plasticized, the chunk rubber blocks are further treated, andthus final finished products are obtained. An automatic feeding device is arranged in a plasticator, frequency-conversion control feeding is conducted through a material position control switch, and thus the automatic feeding function is achieved; and an electromagnetic wave controller is arranged in a treatment box in the plasticator and used for controlling the heating temperature. Rubber is subjected to three times of rubber mixing and averagely allocated into four refining machines to be refined, so that the refined rubber is stable in quality and high in qualified rate, and the number ofscraps is small; and the whole technical process is complete and smooth, needed manpower and material resources are reduced greatly, the working efficiency is high, and wide application prospects areachieved.
