Double Helix Cone Mixer

The Double Helix Cone Mixer is a highly efficient and precise powder mixing equipment. It features an asymmetric double-helix design that achieves homogeneous mixing through a compound motion mechanism. Widely used in industries such as chemicals, pharmaceuticals, food, and building materials, it is suitable for mixing materials with significant specific gravity differences, heat-sensitive substances, and superfine powders. It offers the advantages of gentle mixing, no residue, and low energy consumption.

Compared to other mixers, the Double Helix Cone Mixer offers the benefits of lower installed power and wide adaptability to various materials without damaging them. It does not generate excessive heat for heat-sensitive materials, does not crush or pulverize granular materials, and prevents stratification or segregation when mixing materials with vastly different densities or particle sizes. It also exhibits excellent adaptability for mixing coarse, fine, and superfine (nano-grade) particles. Without damaging the mixture, the mixer generates composite movements including lifting, convection, shearing, and diffusion within the cone, enabling gentle and thorough mixing.

• Agitation Assembly: Consists of two asymmetric cantilever arms (revolving arms) with a spiral (helix) attached to the bottom of each. The arms have different lengths and revolve around the central axis of the conical container (revolution), while the spirals simultaneously rotate on their own axes (rotation). This compound motion is the key driving force for material mixing.

• Conical Container: Features a vertical conical shape with a wide top and narrow bottom. This clever design facilitates an effective material flow path during mixing, allowing for full circulation within the container and enhancing mixing efficiency.

• Drive System: Comprises the motor, gear reducer, coupling, and other components. The motor provides power, which is transmitted and speed-adjusted by the reducer via the coupling to the agitation assembly, precisely controlling the revolution and rotation speeds to ensure a stable and efficient mixing process.

• Feeding & Discharging Devices: The feed inlet is located at the top for easy material loading. The discharge outlet is at the bottom, commonly equipped with butterfly valves, ball valves, etc. Some models support vacuum loading or pneumatic conveying, meeting diverse feeding and discharging needs for different working conditions and ensuring a smooth production flow.

When operational, the agitation assembly activates. The two asymmetric spirals rotate (self-rotation), lifting material upwards. The arms revolve slowly (revolution), moving material in a circular path. The combined revolution and rotation of the spirals cause material to be drawn in by the rotating spirals and simultaneously dispersed outwards circumferentially. The two upward material streams converge at the top center and flow back downwards, filling the void at the bottom. This creates a complete recirculating flow pattern within the container. Through this series of compound movements involving repeated lifting, dispersion, and convection, materials achieve rapid and uniform mixing.

• Excellent Mixing Performance: Achieves highly efficient mixing. Even for materials with significant specific gravity or particle size differences, it attains an ideal mixing degree with high uniformity, ensuring stable product quality and effectively preventing stratification or segregation.

• Wide Application Range: Exhibits good adaptability to various materials. Whether for heat-sensitive materials, granules, or coarse/fine/superfine particles, it mixes gently without damaging their original properties, meeting the mixing needs of numerous industries like chemicals, pharmaceuticals, and food.

• Simple Operation & Maintenance: The rational structural design makes operation straightforward and easy to learn. Daily maintenance is also convenient, reducing downtime and improving production efficiency.

• Flexible Customization Options: Can be equipped with additional devices like choppers or spray nozzles based on different process requirements. The shell can be designed as single-wall or double-wall (jacketed) to meet special needs for cooling, heating, or insulation. Various discharge valve options (manual, pneumatic, electric) are available to suit diverse production scenarios.

The Double Helix Cone Mixer is used for mixing powders with powders, liquids with liquids, and powders with liquids across various industries including chemicals, battery materials, coatings, dyes, pesticides, pharmaceuticals, food, feed, additives, refractory materials, new materials, plastics, rubber, ceramics, fertilizers, metallurgy, mining, dry-mix mortar, and special building materials.

• Chemical Industry: Various chemical powders and liquid raw materials, such as polymers, pigments, and additives, meeting the mixing process requirements for different chemical products.

• Pharmaceutical Industry: Pharmaceutical raw materials, intermediates, and excipients, ensuring the mixing process complies with stringent pharmaceutical quality standards and safeguards drug quality and safety.

• Food Industry: Various food ingredients like flour, sugar powder, and additives, achieving uniform mixing without damaging the nutritional components of the materials.

• Pesticide Industry: Pesticide technical materials and additives, ensuring the accuracy and stability of pesticide formulation mixing and improving pesticide efficacy.

• Other Industries: Provides reliable mixing solutions for materials in industries like battery materials, coatings, dyes, feed, additives, refractory materials, and new materials, promoting production development in these sectors.

• Daily Inspection: Regularly check the equipment exterior for damage or deformation, and ensure all connections are tight. Inspect the drive system to confirm the motor and reducer run smoothly without abnormal noise or vibration. Tighten or repair any issues promptly.

• Cleaning: Clean residual material from inside the equipment promptly after each use to prevent buildup that could affect mixing performance. Pay special attention to cleaning the agitation assembly, inner wall of the container, and discharge outlet to avoid material residue corroding the equipment.

• Lubrication: Lubricate all moving parts regularly as specified in the user manual. Use appropriate lubricants to ensure sufficient lubrication, reduce wear, and extend service life.

• Electrical System Maintenance: Regularly inspect the electrical system to ensure secure wiring connections, free from short circuits or open circuits. Check if electrical components are functioning properly and replace any damaged parts promptly to ensure electrical safety during operation.

• Periodic Overhaul: Conduct a comprehensive overhaul at regular intervals. Inspect key components like the agitation assembly, spirals, and bearings for wear and replace if necessary. Simultaneously, calibrate the equipment’s precision to ensure stable and reliable mixing performance.
