Double Helix Cone Mixer

The double helix cone mixer is an efficient and precision powder mixing equipment. It adopts an asymmetric double helix design and achieves uniform material mixing through compound motion. Widely used in chemical, pharmaceutical, food, building materials and other industries, it is suitable for mixing needs of materials with large specific gravity differences, heat - sensitive materials or ultra - fine powders. It also has the advantages of gentle mixing, no residue and low energy consumption.

Compared with other mixers, the double helix cone mixer has the advantages of low installed power, wide adaptability to mixed materials and no damage to mixed materials. It will not cause overheating to heat - sensitive materials, not crush or grind granular materials, and will not cause stratification and segregation when mixing materials with large specific gravity differences and different particle sizes. It also has good adaptability to the mixing of coarse materials, fine materials and ultra - fine particles (nano - level). Without damaging the mixture, the double helix cone mixer generates compound motions such as lifting, convection, shearing and diffusion in the cone, which can gently mix materials to achieve the mixing effect.

Main Structure:

• Mixing Components: Composed of two asymmetric cantilevers (swing arms) and two spirals below. The cantilevers have different lengths and rotate around the central axis of the conical container (revolution), while the spirals rotate on their own axes. This compound motion mode is the key power source for material mixing.
• Conical Container: It is in the shape of a vertical cone with an ingenious structure design of being wide at the top and narrow at the bottom. During material mixing, it is conducive to forming a good material flow path, enabling materials to circulate fully in the container and improving the mixing effect.
• Drive System: It includes components such as a motor, a reducer and a coupling. The motor provides power, which is adjusted by the reducer and then transmitted to the mixing components through the coupling. It accurately controls the revolution and rotation speeds to ensure a stable and efficient mixing process.
• Feeding and Discharging Device: The feeding port is located at the top for convenient material feeding; the discharging port is set at the bottom, and common forms include butterfly valves and ball valves. Some equipment also supports vacuum feeding or pneumatic conveying to meet the feeding and discharging needs under different working conditions and ensure a smooth production process.

Working Principle:

When the equipment is in operation, the mixing components start to work. The two asymmetric spirals rotate on their own axes to lift the materials upward; the cantilevers revolve at a low speed to drive the materials to make circular circulation motion. The revolution and rotation of the spirals cooperate with each other, so that the materials are absorbed by the spiral rotation and scattered in the circumferential direction at the same time. The two material flows lifted to the upper part then converge to the center, forming a downward flow direction at the center to fill the empty area at the bottom, thus forming an overall circular flow in the container. Under this series of compound motions, the materials are repeatedly lifted, diffused and convected to achieve rapid and uniform mixing.

Maintenance:

• Daily Inspection: Regularly check whether the equipment appearance is damaged or deformed, and whether all connection parts are loose. Check the drive system to ensure that the motor and reducer run smoothly without abnormal noise and vibration. If problems are found, fasten or repair them in time.
• Cleaning and Maintenance: After each use, clean the residual materials inside the equipment in time to prevent material accumulation from affecting the mixing effect and equipment performance. Pay special attention to cleaning the mixing components, the inner wall of the container and the discharge port to avoid equipment corrosion caused by residual materials.
• Lubrication Maintenance: According to the requirements of the equipment operation manual, regularly lubricate all moving parts. Select appropriate lubricants to ensure sufficient lubrication, reduce equipment wear and extend service life.
• Electrical System Maintenance: Regularly check the electrical system to ensure that the circuit connections are firm without short circuits or open circuits. Check whether the electrical components work normally. If they are damaged, replace them in time to ensure the electrical safety of the equipment operation.
• Regular Overhaul: Conduct a comprehensive overhaul at regular intervals. Check key components such as mixing components, spirals and bearings to see their wear conditions, and replace them if necessary. At the same time, calibrate the accuracy of the equipment to ensure that the mixing effect is always stable and reliable.
