Used for smooth and gentle blending of dense powders and abrasive material. This machine can handle large volumes and is easily cleaned. Separately driven internal lump breakers can be provided for braking of lumps and agglomerates. The unit consists of two cylindrical cones welded together and fitted with shaft mounted on bearings. The blender is rotated at slow RPM because of which the entire mass is tumbled along the angle of the cone resulting in criss crossing of the material to produce a uniform mix. Baffles are provided inside the cone for throughout mixing.
