Construction: Double cone blender is made up of stainless steel and is available in different capacity ranging from 5 kg to 200 kg or even more. The efficiency of the blender depends mainly on the speed of rotation. The rate of rotation should be optimum which depends on the size and shape of tumbler as well as nature of material to be mixed. The common speed of rotation is of about 30-100 rpm. 


Working: The material to be blended is loaded in approximately 50-60% capacity of conical shaped vessel. As the blender rotates, the material undergoes tumbling motion and mixes the material thoroughly. Agitator blade can also be used in order to produce shearing action and design is useful for mixing powders of different densities in small quantities.
