Charles Ross and Son Company offers the vertical blender for the blending of easily degradable solids. The mixing screw rotates around the periphery of the cone and simultaneously lifts materials from the bottom to the top of the blender. This dual blending action results in short cycle times. Vertical blenders are ideal for use in blending high-density powders, as less power is required than when using horizontal blenders. The unit also discharges fully and is easily cleaned. Designs are available from one through 500 cubic feet. A variety of options are available including choppers for size reduction, spray nozzles for minor liquid addition and cleanout doors.
