Single Helix Cone Mixer

The Single Helix Cone Mixer is an industrial mixing equipment designed for powders, granules, and solid-liquid materials. Featuring a conical vessel and a single helix structure, it ensures residue-free discharge and is widely used for homogeneous mixing in industries such as chemicals, pharmaceuticals, and food additives. After materials enter the vessel through the top feed port, the helix shaft, driven by a compound motion of revolution and rotation, creates triple mixing effects: convection, shearing, and diffusion. The material is lifted along the conical wall to the top and then falls back naturally, achieving uniform distribution both circumferentially and axially.

The Single Helix Cone Mixer is primarily composed of the helix system, drive unit, and main body structure:

• Helix System: A single helix shaft drives material circulation through the compound motion of rotation (on its own axis) and revolution (around the vessel axis).

• Drive Unit: The movements from the rotation motor and the revolution motor are adjusted to appropriate speeds via a worm gear system and gears, then transmitted to the helix to achieve both rotational and revolutionary motions.

• Vessel Cover: The cover supports the entire drive assembly, which is fixed to it. The cover is equipped with a feed port, observation port, cleaning port, and maintenance access.

• Vessel Body: The conical vessel holds the material, facilitating rapid and complete discharge without accumulation or dead spots.

• Discharge Valve: Located at the bottom of the vessel to control material retention and discharge. Available in manual, pneumatic, or electric configurations. A liquid discharge valve can be added upon request.

• Spray System (Optional): Supports solid-liquid mixing processes with uniformly distributed spray nozzles.

The mixer uses a cycloidal reducer to drive the central screw and the outer ribbon helix at the same speed. During operation, the central screw lifts material from the bottom to the top. Simultaneously, the outer ribbon helix, with a higher linear speed, sweeps and lifts material upward along the conical wall. Both motions, under centrifugal force, throw the material tangentially into space, creating intense convection, shearing, and diffusion, thereby achieving rapid and thorough mixing. (The central screw can also be designed for reverse rotation.)

• No Dead-Spot Mixing: The combination of the conical wall and ribbon helix/scraper design effectively eliminates material残留 (residue) dead spots, enhancing mixing uniformity.

• Strong Adaptability: The ribbon helix/scraper efficiently handles materials with poor flow or certain viscosity, reducing wall sticking.

• Flexible Operation: The central screw supports forward or reverse design, allowing mixing methods to be adjusted based on material characteristics.

• Smooth Operation: Driven by a cycloidal pin gear reducer, ensuring stable running, low noise, and reduced energy consumption.

• Wide Application Range: Compatible with mixing requirements for various material forms like powders and liquids, meeting multi-scenario production needs.

The Single Helix Cone Mixer is commonly used across industries including chemicals, metallurgy, food, pharmaceuticals, fertilizers, coatings, pigments, dyes, pesticides, rubber, feed, additives, refractory materials, fine chemicals, new materials, plastics, ceramics, mining, and building materials. It offers wide adaptability for mixing powders, granules, slurries, or pastes. It can be equipped with a spray system and customized for vacuum, pressurized, heated, or cooled process conditions to meet diverse mixing and stirring needs. It does not overheat heat-sensitive materials, does not crush granular materials, and prevents stratification when mixing materials with vastly different densities or particle sizes. It also shows good adaptability for mixing coarse/fine/superfine particles, fibers, or flakes.

• Regular Inspection: Before operation, check that drive system connections are secure and that the helix/ribbon is not loose or deformed.

• Cleaning: Clean residual material from the vessel promptly after each use to prevent buildup and caking that could affect future mixing.

• Lubrication: Regularly add suitable lubricant to the reducer and rotating parts to ensure smooth operation.

• Load Control: Avoid overloading the equipment by exceeding the maximum feed capacity to extend its service life.

• Fault Handling: If abnormal noise or vibration occurs during operation, stop the machine immediately for inspection. Only resume use after troubleshooting.
