Share the mechanical effect of rubber material in internal mixer!
Because the surface of the rotor has a spiral sharp edge, the gap between it and the mixing chamber is variable, and the small gap is between the edge of the rotor of the mixer and the wall of the mixing chamber. When the rubber material passes through this small gap, it is strongly squeezed, sheared and stretched, which is similar to the function of the distance between two rolls of the open mill, but the effect is much greater than that of the open mill. The reason is that the velocity gradient between the rotating rotor and the fixed chamber wall is much larger than that of the open mill, and the transmission angle between the rotor tip and the mixing chamber wall is sharp.
