Products Description
Need a high-performance mixer for powders, granules, or solid-liquid blending without particle degradation?
Guanjiang's Cantilever Double Spiral Cone Mixer is a new-generation mixing solution designed for efficient, homogeneous blending of diverse materials. With dual planetary motion (rotation and revolution), it delivers fast mixing (<10 minutes), handles materials with extreme density differences, and gently blends without overheating or crushing. Available in capacities from 0.3 to 30m³, it's ideal for chemical, pharmaceutical, food, fertilizer, and mineral processing industries.
Key Advantages
Dual planetary motion creates intense convection and diffusion, achieving uniform mixing in 5-15 minutes. No segregation, even for materials with varying densities or particle sizes.
Low-speed operation with no crushing or overheating — preserves particle integrity for fragile crystals, fibers, flakes, and heat-sensitive materials.
Two asymmetrical spiral screws create planetary movement, agitating material throughout the entire cone — zero dead corners, complete discharge.
Low power consumption with high loading capacity (0.3-1.0 loading factor). Compact footprint saves valuable floor space compared to traditional mixers.
Available in carbon steel, stainless steel (304/316L), explosion-proof, jacketed, and heavy-duty models. Adaptable to your specific application requirements.
Equipped with spray system for adding liquids into dry powders — ideal for granulation, coating, or wet mixing.
Fully enclosed operation with safety interlocks, GMP-compliant designs available (stainless steel, polished surfaces).
Working Principle & Structure
Two-Screw Planetary Motion: The mixer combines two independent motions — rotation (self-spinning of each screw) and revolution (orbital movement around the cone wall).
- Self-Rotation: Each spiral screw rotates on its own axis, lifting material from the bottom upward along the cone wall.
- Revolution: Both screws orbit around the central axis, sweeping the entire cone volume and creating intense cross-flow.
This dual action creates a continuous convection-diffusion cycle, moving material upward along the wall and downward in the center, achieving uniform mixing in a short time.
Key Components
- Drive Unit: Two independent motors for rotation and revolution
- Spiral Screws: Asymmetrically arranged for maximum agitation
- Cone Vessel: Tapered design for complete discharge
- Spray System: Optional liquid addition via rotating nozzles
- Discharge Valve: Manual, pneumatic, or electric (with liquid-valve option)
Key Benefits
- No particle attrition or overheating
- No segregation for density/size differences
- Ideal for fine powders, fibers, and flakes
- High loading factor (0.3-1.0)
- Compact, space-saving design

Frequently Asked Questions
Q1: What materials are best suited for the DSH double spiral cone mixer?
A: The DSH mixer handles powders, granules, fibers, flakes, and solid-liquid mixtures. It's ideal for heat-sensitive, fragile, and abrasive materials due to its gentle, low-speed operation. Works well for materials with extreme density differences (no segregation) and fine powders (<100 mesh).
Q2: How does this mixer handle materials with different densities or particle sizes?
A: The dual planetary motion creates strong convection and diffusion. Materials are continuously lifted along the cone wall and dropped in the center, preventing segregation or layering — even for density ratios up to 10:1 or particle size variations from 5µm to several mm.
Q3: What is the typical mixing time for a batch?
A: Most materials achieve uniform mixing in 5-15 minutes. The time varies based on material properties and loading volume. The high-intensity convective flow from the double spiral design significantly reduces mixing time compared to V-type or ribbon blenders.
Q4: Can liquids be added during mixing?
A: Yes. The mixer is equipped with a rotating spray system that allows liquids (binders, coatings, oils) to be added during the blending cycle. This is ideal for wet granulation, coating, and solid-liquid blending applications.
Q5: What's the difference between the DSH mixer and a V-type or ribbon mixer?
A: DSH double spiral cone mixer offers higher loading capacity (0.3-1.0 factor), more gentle mixing (no crushing), and handles wider material ranges (fibers, flakes, sticky materials). V-type mixers are better for free-flowing powders and have lower loading capacity (40-50%). Ribbon blenders are best for continuous high-volume mixing but can shear fragile materials. Choose DSH for versatility, gentle handling, and large batches.
