Working of Double Cone Blender

The powder is filled up to two-thirds of the volume of the blender to ensure proper mixing. The rate of rotation should be 30-100 revolutions per minute. On rotation, mixing occurs due to tumbling motion. The product can be discharged from the bottom of the equipment. The mixing tank can be slanted freely at the angle of 0° to 360° degrees for discharging and cleaning purposes.
