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 ¡ª 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 ¡ª 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 ¡ª ideal for granulation, coating, or wet mixing.

Fully enclosed operation with safety interlocks, GMP-compliant designs available (stainless steel, polished surfaces).

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 ¡ª even for density ratios up to 10:1 or particle size variations from 5?m 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.
