Structure principle
The SHJ double-screw cone mixer makes the powder move circularly along the cone wall due to the revolution of the double helix. The rotation of the helical blade of the SHJ double-screw cone mixer causes the powder to discharge radially toward the center of the cone. The powder is discharged from the cone toward the upflow and spiral outer circumferential surface, that is, the direction of the spiral axis. The combination of the rotation and rotation of the screw of the SHJ twin-screw conical mixer in the mixer resulted in the four flow forms of the powder, namely, convection, shearing, diffusion and infiltration. Therefore, the powder material can quickly and uniformly mix in such a mixer.
working principle
SHJ double-screw conical mixer produces the compound motion in the cone by the spiral's male and female rotation movements. It mainly produces four kinds of movement forms:
(1) The spiral orbits along the wall to make the material move circularly along the cone wall;
(2) spiral rotation so that the material rises from the bottom of the cone along the spiral;
(3) The spiral's combination of male and female rotation causes a part of the material to be in the cylindrical surface of the spiral, and at the same time is subjected to the centrifugal force of the spiral rotation so that a part of the material in the cylindrical surface of the spiral is discharged radially to the cone;
(4) The rising material is reduced by its own gravity. The four kinds of motion produce convection, shearing, and diffusion in the mixer, so as to achieve the purpose of rapid and uniform mixing.
Features
1. With advanced structure, convenient operation, safe and reliable operation, the screw shaft has no bottom bearing, it clears the fault caused by the leakage of the bottom bearing.
2, the mixing speed is fast, the mixing quality is even. The double helix of the machine is arranged asymmetrically, which enlarges the stirring range from one big to the other. Therefore, it is more suitable for the mixture with special proportions and special mixed mixture ratio. Short mixing time, high mixing uniformity and clean discharge.
3, energy-saving effect is remarkable, the machine and the drum mixer energy consumption is only about one-tenth.
4, the mixing process is mild, the material will not produce pressure feed, wear, overheating.
5. The formulation after mixing is stable without delamination and segregation.
6, double spiral cone mixer seal dust, simple operation and easy maintenance. Long service life, but also according to user requirements, the cone into a pressure vessel can be pressurized vacuum operation.
