Bin blenders consists of a storage container which holds the materials, and also doubles up as blending vessel. Materials to be blended are loaded in the container and the container is attached to an independent blender drive system. After blending is completed the container is moved to the storage area and another similar container is mounted on the drive system. As the transfer of blended material from blender to a storage container is eliminated, it eliminates the chances of segregation of blended material. Moreover, no cleaning between batches is required. The Bin blender is popular with pharmaceutical, food and powdered metal industries.
