Ross’s investment in its people and facilities for over 170 years has yielded a proud history of innovation in sanitary mixing, dispersing, emulsification, and drying. In the early 1900s, Ross introduced the “Pony Mixer,” the world’s first change-can mixer. With the “Versa-Mix,” Ross was the first to offer the flexibility and efficiency of three independently driven agitators in one piece of mixing equipment. The “MegaShear” ultrahigh shear rotor–stator mixer and the “SLIM” high-speed powder injection system have advanced processing productivity even further. Today, Ross innovations also are producing significant advances in discharge systems, storage tanks, pressure vessels and reactors, and integrated process control systems.
