The double helix cone mixer is a high-efficiency powder mixing equipment widely used in chemical, pharmaceutical, food, pesticide, metallurgy and other industries. Its unique design and compound movement mechanism enable it to excel in mixing speed, uniformity and adaptability. The following is a detailed introduction from the aspects of working principle, core advantages, structural features and selection key points.

 

The core component of the double helix cone mixer is two asymmetrically arranged helical stirrers installed inside a vertical conical container. During operation, the helices perform both rotation and revolution: rotation lifts the bottom materials upward, forming axial flow; revolution drives the materials to move circularly along the cone wall. This compound movement causes the materials to undergo convection, shear, diffusion and infiltration in the machine, thereby achieving rapid and uniform mixing, and effectively preventing stratification or segregation.

 

1. Efficient Mixing: The compound movement mechanism ensures that materials achieve high uniformity in a short time, with fast mixing speed and low energy consumption.

2. Wide Adaptability: Suitable for materials with specific gravity, large particle size difference or proportion. It will not cause overheating to heat-sensitive materials, and has little compression and wear on granular materials.

3. Compact Structure: Small footprint, and the bottom discharge valve design enables quick and thorough discharge, facilitating cleaning and material change.

4. Good Sealing Performance: The two-way full-sealing structure avoids dust pollution, improves working conditions and supports continuous production.

5. Strong Customizability: Jackets (for heating or cooling), liquid spraying systems (for liquid-adding mixing) or pressure-resistant designs can be added according to requirements to meet special process requirements.

 

- Drive Mode: There are two configurations: single-motor drive and dual-motor drive, selected according to material properties and process requirements.

- Discharge Device: Plum blossom dislocation valves, powder spherical valves or butterfly valves are adopted to reduce mixing dead corners and ensure thorough discharge.

- Material Selection: The equipment can be made of carbon steel, stainless steel (304, 316L, etc.) or anti-corrosion coatings to meet the hygiene and corrosion resistance requirements of different industries.

- Auxiliary Components: Supports the addition of jacket temperature control, liquid spraying systems or negative pressure feeding functions to enhance equipment applicability.

 

When selecting a double helix cone mixer, the following factors should be comprehensively considered:

1. Material Characteristics: Including particle size, specific gravity, viscosity and corrosiveness, to ensure that the equipment material and structure are suitable.

2. Process Requirements: Select according to the mixing batch volume (common specifications are 0.1-20 cubic meters), mixing accuracy and whether heating, cooling or liquid-adding functions are required.

3. Industry Standards: For example, the pharmaceutical industry needs to comply with GMP standards, and the food industry needs to meet hygiene requirements, ensuring that the equipment design conforms to the specifications.

4. Operation and Maintenance: Priority is given to models with simple structure, convenient cleaning and stable operation to reduce long-term use costs.

 

With its efficient, flexible and reliable characteristics, the double helix cone mixer has become an ideal choice in the field of powder mixing. Through reasonable selection and configuration, production efficiency and product quality can be significantly improved.
