Charles Ross & Son Co. has new mixing equipment for blending of powder and liquid materials. The company’s laboratory paddle blender facilitates preparation of dry solid mixes and can also accommodate minor liquid additions. A customized version of its VersaMix triple-shaft mixer adds a turnkey system that can extrude finished products into strands. For its 150-gallon multi-shaft mixer, the manufacturer added automation and safety functions to improve blending and dispersal of viscous products. In addition, it rolled out two 150-gallon double planetary mixer models for high turnover of thick or putty-like materials up to 2 million centipoise. Web: www.mixers.com
