The Double Cone Blender consists of two cylindrical tanks with a feeder to each, which is hinged at the top. The two bowls of the blender are placed upside down on the two feeders and the motor and the blades of the machine can be located on the floor near the bowls. Feeding the blended ingredients into one of the bowls begins the process. The other bowl is used to store finished products and can be conveniently positioned above the first.

The Double Cone Blender has many important advantages. The fact that it combines ingredients effectively means that there is an increase in volume and surface area of the final product. The Double Cone Blender has been found to be very useful for blending, homogenizing, emulsifying and separating pharmaceutical granules. The ability to use small bowls makes it easier to control the temperatures and also reduces the spill effect associated with emulsifiers.

Some users of the Double Cone Blender have reported problems using the machine when the bowls are too hot. This problem can be overcome by adjusting the setting to the desired level and checking to see if the machine produces dry blends. It is interesting to note that the temperature of the water used to pre-heat the dry blending components can influence the operation of the machine. To test this hypothesis, some users have switched the machine on and off in different temperatures of water used to heat the feed basin. The results showed that the temperature of the water influenced the operation of the machine to some extent. In most cases this was not a problem and the Double Cone Blender performed satisfactorily.
