When the internal mixer is working, the two rotors rotate relative to each other, clamping the material from the feeding port and bringing it into the roller gap. It is squeezed and sheared by the rotor, passes through the roller gap, and then hits the lower top bolt. The sharp edge is divided into two parts along the front and rear chamber walls. The gap between the roller and the rotor returns to the top of the roller gap. During the flow around the rotor, the material is subjected to shear and friction everywhere, causing the temperature of the rubber to rise sharply, the viscosity to decrease, and the wettability of the rubber on the surface of the compound to be fully contacted with the surface of the compound. The compound clumps along with the rubber material are sheared and broken through the gap between the rotor and the rotor, the gap between the rotor and the upper and lower top bolts, and the inner wall of the mixing chamber. They are surrounded by the stretched and deformed rubber and stabilized in the broken state. At the same time, the convex ribs on the rotor make the rubber material move along the axial direction of the rotor to stir and mix, so that the compounding agent is evenly mixed in the rubber material. The compounding agent is repeatedly sheared and broken, and the rubber material is repeatedly deformed and restored to deformation. The continuous stirring of the rotor ridges makes the compounding agent disperse evenly in the rubber material and achieve a certain degree of dispersion. Since the shearing effect of the rubber material during mixing in the internal mixer is much greater than that of the open mixer, the rubber mixing temperature is high, so the rubber mixing efficiency of the internal mixer is much higher than that of the open mixer.
