Summary
SHJ series twin screw conical mixer is a new type of high efficiency and high precision mixing equipment. The machine adopts a set of motor and cycloidal pin wheel reducer to form revolution and rotation. The principle of combining the rotation motion of long and short mixing screws with the rotation motion of two screws is used to make the materials with large proportion ratio reach the ideal mixing degree, with short mixing time and good effect. Widely used in pharmaceutical, food, chemical, pesticide, feed, petroleum, metallurgy, mining, building materials industry, coating and other industries of various powder mixing.
main features
1. Advanced structure, convenient operation, safe and reliable operation, no bottom bearing for spiral shaft, eliminating the fault caused by powder leakage of bottom bearing
2. The mixing speed is fast and the mixing quality is even. The double helix of the machine is arranged in an asymmetric way, with one large and one small to expand the mixing range, so it is more suitable for materials with large specific gravity and special mixing ratio. Short mixing time, high mixing uniformity and clean discharge
3. The energy saving effect is remarkable. Compared with the drum mixer, the energy consumption of this machine is only about one tenth of that
4. The mixing process is mild, and the materials will not be pressure fed, worn or overheated
5. The mixed preparation is stable without stratification and segregation
6. The mixer is dust-free, easy to operate, easy to maintain and long in service life. In addition, the cone can be made into a pressure vessel for pressure or vacuum operation according to the user's requirements
7. Materials are divided into carbon steel and stainless steel, which can be selected according to the user's needs
Working principle
1. Because of the revolution of the double helix, the powder moves in a circle along the cone wall
2. Due to the rotation of the spiral blade, the powder is discharged to the center of the cone for radial movement
3. The powder flows upward from the cone and is discharged from the surface of the outer circumference of the spiral, i.e. mixed in the direction of the spiral axis
4. Because of the combination of revolution and rotation of the screw in the mixer, the four flow forms of the powder, namely, the compound motion of convection, shear, diffusion and infiltration, are created. Therefore, the powder material can be quickly and evenly mixed in the mixer.
