Charles Ross & Son added a 1-cubic-foot Ribbon/Paddle Blender and a 2-gallon Planetary Dual Disperser to its Ross Test & Development Center, which also houses other mixing, blending and dispersion equipment. Both machines are rated for vacuum operation, equipped with a jacketed vessel for heating/cooling and are capable of variable speed and automated discharge. A 5-cubic-foot Tumble Blender with mirror finish V-cone vessel and integrated controls is also available for mixing trials. A wide range of non-hazardous applications can be safely handled at this testing facility.
