The difference between rubber shear rubber mixer and mesh rubber mixer

In the production of rubber and plastic mixing, an internal rubber mixer or an open rubber mixer is often used to mix, knead and disperse the rubber. Internal rubber mixer equipment can be divided into two basic types: shearing type and meshing type. The following is a brief description of the difference between a shear rubber mixer and an intermeshing rubber mixer. The internal rubber mixer has large capacity, short time and high production efficiency, which can effectively avoid dust flying, reduce the loss of compounding agents, and improve product quality and working environment.

Here is the list

• Shear rubber mixer

• Intermeshing rubber mixer

• The difference and comparison of the shear rubber mixer under the intermeshing rubber mixer

Shear rubber mixer

The shear rubber mixer mainly mixes materials between the rotor edge and the inner wall of the rubber mixer to form a high shear force. The rotor edge rotates the mix axially and radially. The gap between the top of the rotor and the internal rubber mixer is crushed and dispersed, and the two rotors mainly act on the material by shearing, so it is called a shearing internal rubber mixer.

Intermeshing rubber mixer

The mixing action of the intermeshing rubber mixer takes place in the intermeshing area between the two rotors. The rotor of the meshing rubber mixer must be driven by a constant speed connecting gear. The interaction between the large diameter of one rotor and the small diameter of the opposite rotor determines that the rotor must be at a constant speed. During operation, there are ridges on the rotor of the internal rubber mixer, and the ridges are spiral along the rotor, so that the mixed material moves axially in the mixing chamber, and the dispersion and mixing are mainly carried out in the small gap between the two. Large and small rotors. Since the outer diameter of the rotor rib is larger than the center distance of the rotor, the rubber compound will be deformed by the kneading and squeezing action of the top when it is squeezed into the space between the two rotors. During the mixing process of the compound, it is subjected to strong force. It can enhance the mixing effect and increase the heat conduction of the material. The tensile strength, scorch time, elongation at break and production efficiency of the final mixed rubber are better than those of the mixed rubber mixed by the shear rubber mixer. High lift.

The difference and comparison of the shear rubber mixer under the intermeshing rubber mixer

1. The shear rubber mixer has high mixing efficiency;

2. The shearing rubber mixer heats up quickly, but it is not easy to produce glue;

3. The dispersion effect of the meshing rubber mixer is better than that of the shear rubber mixer;

4. Compared with the meshing rubber mixer, the energy consumption is higher;

5. The intermeshing rubber mixer is sensitive to low filling rate.
