This type of blender features an auger that turns on its own axis and a mechanical arm that rotates the auger around the conical vessel. The blending action is far gentler than that of horizontal blenders, making it more suitable for delicate and abrasive applications. Spray nozzles may be installed for liquid addition and coating purposes. Vertical blenders are also commonly used in vacuum drying operations and can accommodate a wide range of feed forms – from slurries, wet cakes, and pastes, to granules, pellets, and powders. An important standard design feature is the absence of a bottom support bearing. This facilitates complete discharge and simplifies cleaning. Many sizes from 1- through 500-cu-ft capacities are available, including sanitary models. Charles Ross & Son Co., Hauppauge, NY 800-243-7677 www.mixers.com

Powder and Liquid Delivery System
Booth 725 - The Solidquid powder and liquid delivery system automatically and precisely delivers dry bulk ingredients into a motive liquid stream to convey slurries, solutions, or suspensions into a mix tank, blender, or other process equipment. In addition to reducing mix times, the Solidquid instantly creates non-viscous mixtures, which eliminates the need for additional conveyors, saves maintenance and energy costs, creates less dust, uses less floor space, and offers more flexibility in equipment layout. Material is discharged from a bulk bag unloader frame into a feeder, which volumetrically or gravimetrically measures it into a solids eductor. Motive process liquid supplied to the eductor inlet creates a vacuum, pulling the dry material into suspension and disperses them evenly into the effluent flow. Hapman, Kalamazoo, MI 800-427-6260 www.hapman.com
