Working principle of triple helix cone mixer

The working principle of the triple screw conical mixer can be clearly divided into the following points:

Basic structure and composition:

The three-spiral conical mixer is mainly composed of a fixed conical cylinder, three spiral shafts and transmission device and other parts.

The cylinder is conical, fixed on the support, not rotating with the spiral shaft.

There is a feeding port at the top of the cylinder and a discharging port at the bottom, and a discharging valve can be opened and closed.

Three spiral shafts (usually two short and one long symmetrically arranged) are coupled with a rotating arm tie rod, symmetrically and vertically installed near the inner wall of the cylinder.

Spiral shaft movement:

Spiral shaft is driven by the transmission device, around the cylinder wall for planetary slow rotation, usually 5r/min (speed may vary according to specific models and applications).

At the same time, the spiral shaft itself also carries out rapid rotation, rotation speed is usually 110r/min (rotation speed may also vary according to specific models and applications).

Material mixing process:

After the material is added from the top of the cylinder, under the action of the rotation and spinning of the spiral shaft, the material carries out complex convection, shearing, diffusion and other movements in the cylinder.

Spiral along the wall of the rotary material along the wall of the cone for circular motion, the spiral rotation of the material from the bottom of the cone along the spiral rise, while the rotation of the spiral will also be part of the material absorbed into the spiral cylindrical surface, and to the cone radial discharge.

The rising material is lowered by its own gravity, forming the triple mixing effect of convection circulation.

Mixing effect and characteristics:

Through the three-dimensional movement of the spiral shaft, the materials can be fully and evenly mixed in the cylinder.

The design of the three spiral makes the material in the mixing process can form more convection and shear, further improve the mixing uniformity.

It is suitable for mixing all kinds of powder and granular materials, especially suitable for occasions with high requirements for mixing uniformity.

Drive and control:

The drive device usually consists of an electric motor and a cycloid reducer, which is installed in the center of the cylinder top cover.

According to the need, the mixing process can be adjusted by controlling the speed and time of the motor to meet the mixing requirements of different materials.

To summarize, the three spiral conical mixer realizes the rapid and uniform mixing of materials through the rotation and spinning of the spiral shaft and the convection, shear, diffusion and other movements of materials in the cylinder. Its unique structure and movement makes it widely used in many industries, and can meet the high requirements for mixing uniformity of the material mixing needs.
