The laboratory mixer is composed of a mixing chamber, two relatively rotating rotors, an upper top bolt, a lower top bolt, a temperature measuring system, a heating and cooling system, an exhaust system, a safety device, a discharge device and a recording device. The surface of the rotor has a spiral convex edge, the number of the two edges, the edge of the prism, the six edges, and so on, the geometry of the cross-section of the rotor is triangular, cylindrical or oval, there are two types of tangential and meshing type of.

The working principle of the mixer is that when the mixer operates, the two rotors rotate relatively, and the material coming from the feeding port is clamped into the roller gap to be squeezed and sheared by the rotor

Then, the top edge of the bottom edge is divided into two parts, and the gap between the front wall and the back wall is returned to the top of the roller gap. In the flow around the rotor

In the middle of the week, the material is subjected to shearing and friction, so that the surface of the rubber and the complexing agent is fully contacted. The complexing agent is connected with the rotor through the rotor and the rotor through the glue

The gap between the inner wall and the inner wall of the chain is cut and broken, and the rubber is stretched and deformed. At the same time, the mixer rotor

The convex edge causes the rubber material to move along the axial direction of the rotor, so as to stir and mix.
