Double Cone Blender

Gentle cascading gravity blending — the cleanest, most sanitary choice for pharmaceutical powders and granules.

Double Cone Blender

About the Double Cone Blender

The Double Cone Blender features a conical shape at both the loading and discharging ends, connected by a central cylindrical section. As the vessel rotates, the material charge naturally cascades from the top cone through the central section and into the bottom cone. This cascading gravity flow produces a highly efficient and well-distributed blend with minimal energy input and near-zero shear force.

The smooth, crevice-free geometry makes the Double Cone the preferred blender in GMP pharmaceutical environments — it is exceptionally easy to clean and sanitise, eliminates product traps, and supports reliable CIP. Its gentle action makes it particularly suited to fine powders that might agglomerate in more aggressive mixers.

Key Applications

Core Advantages

Gentle Low-Shear Mixing
Cascading action prevents particle breakdown — maintains granule integrity and particle size distribution.
Superior Cleanability
Smooth, crevice-free, fully polished internals with no internal shaft or paddles — fastest CIP in its class.
Optimal for Fine Particles
Effectively handles fine powders that agglomerate in more aggressive mixers.
Minimum Energy Consumption
Natural gravity-flow blending is highly energy efficient relative to blend quality achieved.
Zero Cross-Contamination Risk
Fully enclosed vessel with no internal moving parts in contact with product — ideal for potent APIs.
Scalable Design
Standardised geometry allows predictable, validated scale-up from pilot to production.
