Working principles
Double screw conical mixer rotated around its axes by right of two internal asymmetric spirals which is installed on the cantilever. Meanwhile, the rotational force from the cantilever drives two spiral doing revolution around a conical chamber axle wire.

The double screw conical mixer has 4 direction forces.

• Two inner asymmetric spiral upgrade materials by rotation.
• Tumbler low-speed rotation makes material circle motion.
• Spiral rotation and revolution make materials absorbed while diffuse to circle direction.
• Two flow materials upward then down to the center, which come into being a downward material flow. This way can full the bottom gap and form a convective circulation.

1. Flexible material selection

The material can be carbon steel, manganese steel, ss304, 316L, and 321; different material can also be used in parts, between the part contact with the raw material and the parts don't contact with the raw material. Surface treatment for stainless steel can be sandblasting, wiredrawing, polishing, mirror polishing.
2.   Reliable driven unit
The driven unit and power is varied according to different raw material, starting method, and processing.
A double screw conical mixer is equipped with an appropriative double output reducer, which combines pinwheel, gear, and warm and gear.

3.   Excellent discharging unit

The spherical valve or plum-blossom dislocation valve is matched to the double screw conical mixer. The surface of the valve matches the track of the bottom of the screw, to reduce the mixing dead zone to the maximum, and to make the largest discharging area, so as to make sure no leftover. Spherical valve has an excellent sealing effect to powder, liquid, and even in the negative pressure state. Plum-blossom dislocation valve is easy to operate and control the discharging speed;
4.  Powerful auxiliary components

Equipped with the circulation medium of the jacket, the double screw conical mixer can realize the temperature control in the mixing process.

In the mixer barrel, the part contact with material can coat some antiriot, anti-caking, and metal isolation material according to different ingredients. In some severe wear conditions, the screw surface can be overlaid by some wear-proof alloy.

If a small quantity of liquid is required during mixing, spraying, or atomizing unit is necessary in order to mix the liquid evenly with the main ingredient. The liquid-adding system is basically composed of three parts: pressure source, liquid storage pot, and spraying nozzles.
