Abstract
An improved solid particulate matter blender which is essentially a cylindrical vessel with a hopper bottom and a central lift pipe through which pressurized gas is pumped in order to lift material from the bottom to the top for remixing. An internal cone structure mounted inside the conical bottom hopper improves the mixing action within the blender. A cylindrical extension is attached to the bottom of the internal cone structure and extends toward the bottom of the vessel. Material originating at various heights thus reaches the bottom and is lifted to the top together to accomplish the mixing action.
