Mixers & Blenders

Double Cone Blender | gentle for delicate fragile material

Double Cone Blender | Gardner Range

A Double Cone Blender provides gentle, low energy tumbling action making it ideal for blending delicate and fragile products, as well as for mixing very heavy and abrasive products. This type of blender is used to produce a homogeneous mixture and is a better alternative for materials that need to be carefully tumbled, rather than stirred.

Examples of materials mixed in this way include semolina flour, seeds, starch, coffee beans and ground coffee, cocoa, chocolate flakes or powder, powdered milk, baby food, preparations to make dehydrated soups and creams, pharmaceutical granules, detergent granules, soap flakes, artificial fertilizers, plastic in powder ground or pellet form.

Double Cone Blender

Blending Through Unique Design

The mixing action of this Gardner Blender is enhanced by it’s unique Multishear Defector / Disperser Plates, which are positioned along the axis of rotation, within the blending chamber. They deflect blended contents, resulting in a homogeneous blend, regardless of the particle size distribution, shape or density.

The design of the Multishear Defector / Disperser Plates also significantly reduce blending time and ensures there are no dead-pockets of unmixed product; thereby improving efficiency and minimising energy consumption.

Tip: For successful blending, the material should be free-flowing and discharged readily from the upright static blending chamber.


Our Gardner Blender has been designed for hygienic processing and ease of cleaning, along with improved blending efficiency of free-flowing powders and granules.


While Mixers have a moving stirrer or agitator, with a static mixing chamber, blenders are vessels which rotate or tumble in a manner that thoroughly mixes the ingredients inside. This is what makes them the perfect solution for fragile material!

GARDNER Double Cone Blenders are gentle tumble action gravity blenders, making them ideal for fragile and abrasive products alike.

The ‘end-over-end’ tumble action is supplemented and enhanced by internal multi-shear deflector plates, which provide a crossover blending action as the blender cone rotates.

Supported are externally mounted stud arms and bearings, resulting in the Double Cone Blender having no internal shaft seals. This results in an extremely simple and hygienic design to clean and maintain.

In addition, the outlet valve provides ‘total-discharge’ of the material, with no carry-over from batch to batch.

Typical features of the GARDNER Double Cone Blender include:

  • Low energy mixing
  • Internal multi-shear reflector plates
  • Large size range
  • Easy-clean design
  • Total discharge design
  • Low maintenance
  • No Internal Seals or Bearings
  • Blends Fragile Products with Minimal Damage
  • Blends Abrasive Products with Minimal Wear
  • Range from 20L to 100,000L
