Factors affecting the kneading effect of rubber kneader

The rubber kneader is mainly composed of five major parts, such as the mixing and kneading part, machine base part, hydraulic system, transmission system, and electric control system. But do you know about the rubber kneader further knowledge? Read on.

What are the factors that affect the kneading effect of rubber kneader?

1. The characteristics of the material (particle size, adhesion, shape, density, mobility, water content, surface roughness, and the tendency to agglomerate, etc.)

a. Uniform size of the particles kneading, density tends to the bottom of the apparatus.

b. When density is approximated, the smaller and nearly spherical tend to the bottom of the vessel.

c. The greater the viscosity, the higher the temperature, the easier it to agglomerate or agglomerate, not easy to uniformly disperse.

2. Rubber kneader kneading equipment, the way the material is discharged

3. Rubber kneader internal surface roughness (mirror polishing, fine polishing, coarse polishing)

4. Rubber kneader container material loading amount

a. If the loading amount is too much, the kneading space will be less;

b. If the loading amount is too little, it will contribute to low productivity, generally 30% -50% is appropriate.

5. Internal mixer stirring paddle speed: different specifications of the kneader, stirring paddle speed is not the same, such as 37/19, 30/16, 35/25.

Screw kneader working principle: the work of the motor by the reducer drive to the active paddle, after going gear driven by the driven paddle, stirring paddle of the spiral leaves drive the material both for axial pressure, but also do radial pressure; both for high-speed pressure, but also for low-speed pressure; both for the extrusion movement, but also for the separation movement, so that the material after full kneading, rolling, mixing, mixing uniform, accelerate the physical and chemical reaction of the material.

How to form the rubber kneader metric and self-transfer?

Rubber kneader high viscosity fluid mixing, heat transfer, mass transfer (including de-volatilization), and reaction is one of the focus of research on mixing technology in recent years. And for rubber kneader low viscous fluid, the problem has been solved with the traditional propeller, paddle, and turbine impellers. Anchor and frame impellers cover a wide range of viscosities though. But in the higher viscosity domain anchor type Chuan wheel kneading effect is much worse than the spiral belt, and in the low viscosity domain, it is not enough shear stress, axial circulation is also very poor, and because of its paddle diameter on the groove diameter is relatively large, resulting in a large volume of solid turn part, so only the rubber kneader effect is not high requirements of the occasion to use. However, for heat transfer is the purpose of mixing the earth, the anchor impeller is still very suitable for the occasion. Rubber kneader mixing machine when the material is subject to two rotor movement in the opposite direction, in the internal mixer under the role of support, the composite movement, dual-axis paddles drive the material along the inner wall of the slot to do clockwise and counterclockwise rotation, near the axis of the material to do the axis of rotation, the use of U-shaped barrel structure, smooth operation, uniform mixing, no dead space, clean discharge, a wide range of applications.
