Three-phase material rubber continuous mixing mill for preparing rubber compound based on strip-shaped raw rubber

The three-phase material rubber continuous mixing mill comprises a mill body, a mixing cavity is formed in the mill body, a large-diameter feeding port is formed in the inner wall of the upper end ofthe mixing cavity in a penetrating mode, and a discharging blocking door is arranged at the lower end of the mill body. Two symmetrical mixing rollers are rotationally connected to the inner wall of the mixing cavity, an electric heating plate is embedded in the side wall, close to the mixing cavity, of the machine body, a pushing and pressing block opposite to the large-diameter feeding port in position is arranged at the upper end of the large-diameter feeding port, and a limiting ring is fixedly connected to the inner wall of the large-diameter feeding port. And a first inclined plane corresponding to the position of the limiting ring is arranged on the side wall of the pushing and pressing block.
