Particles to be blended are fed into the blender manually or using vacuum suction. The blending vessel needs to be filled with two-thirds of its total volume. The particles are intermixed as the double cone performs a 360-degree rotation. Depending on the properties of the materials, the blending typically takes 10 to 15 minutes to achieve homogeneous mixtures.

This efficient piece of equipment is widely used for the dry mixing of free-flowing solids such as powders and granules. It's capable of producing homogeneous mixtures by blending 2 to 5 ingredients.
