Double Cone Blender

The double cone blender is an efficient and gentle mixing solution for dry powders and granules. It is widely used in the pharmaceutical, chemical, food, and cosmetic industries for achieving uniform blends without particle degradation. The symmetrical cone design ensures free-flowing tumbling action, ideal for sensitive or abrasive materials.

Working Principle

The blender rotates slowly on a horizontal axis. As the material tumbles within the cones, it undergoes continuous division and intermixing. The absence of agitators ensures no particle damage or heating—ideal for heat-sensitive materials.

Applications

  • Pharmaceuticals: Uniform mixing of excipients and APIs, pre-compression blending of granules.
  • Chemicals: Homogenization of pigments, catalysts, and resin powders, blending of additives and intermediates.
  • Food & Nutraceuticals: Mixing of spices, protein powders, vitamins.
  • Cosmetics: Talc and powder mixing.

Advantages:

  • Gentle yet effective mixing
  • Zero material retention and easy discharge
  • Simple cleaning and maintenance
  • GMP-compliant design
  • Low operating cost
