Application Scope:
The Single-cone Double-helix Conical Blender is widely used in various industries such as chemicals, metallurgy, food, pharmaceuticals, chemical fertilizers, coatings, pigments, dyes, pesticides, rubber feed, additives, refractory materials, fine chemicals, new materials, electronic plastics, ceramics, mining, building materials, etc. This blender is highly adaptable to mixed materials, capable of blending, stirring powders, granular materials, pastes, or viscous substances, and can be equipped with a spray and spray irrigation system. It can be designed to operate under vacuum, pressure, heating, or cooling conditions as per customer requirements, meeting the blending and stirring needs of materials under various process conditions. It does not overheat heat-sensitive materials, does not crush granular materials, and does not cause stratification or separation when mixing materials with vastly different specific gravities and particle sizes. It also has good adaptability for blending coarse, fine, ultra-fine particles, fibers, or sheet materials.
Operating Principle:
The rapid self-rotation of the two asymmetric screws within the mixing extruder tube elevates the material, creating two asymmetric spiral streams along the tube wall from bottom to top. The orbital motion of the spiral driven by the arm causes the material outside the spiral to enter the envelope line to varying degrees, with some material being displaced upwards and others ejected from the spiral. This achieves a continuous renewal and diffusion of materials around the circular circumference. The two streams of material raised to the top converge into a central depression, forming a downward flow that fills the bottom void, thus creating a convection cycle. Due to the compound motion, the material achieves uniform mixing in a short time with high mixing accuracy.
Structural Features:
1. Transmission Section: The motion from the self-rotating motor and the rotating motor is adjusted to a reasonable speed through worm gears and gears, and then transmitted to the screw to achieve both self-rotating and rotating movements.
2. Cylinder Cap Section: The cylinder cap supports the entire transmission unit, which is secured to the cylinder cap using screws. The cylinder cap is equipped with a feeding port, observation port, cleaning port, and maintenance hole.
3. Helical section: As the two asymmetrically arranged helices inside the cylinder perform a planetary motion of self- and reciprocal rotation, they effectively flip the material over a wide range, quickly achieving uniform mixing.
4. Cylinder Section: The cylinder is in a conical structure, used for conveying materials, ensuring rapid, clean discharge without material accumulation and no dead corners in the discharge area.
5. Discharge Valve: The discharge valve is installed at the bottom of the cylinder, used for controlling material flow and discharge. This valve comes in three structural forms: manual, pneumatic, and electric. A liquid discharge valve (slurry valve) can be added according to customer requirements.
