Charles Ross & Son Co. recently announced that its double-planetary mixer is available in a reverse-lift design that raises the vessel to the mixing position, rather than lowering the agitator assembly. A reverse lift reportedly facilitates improved rigidity and more uniform blade-to-vessel clearances without relying on the floor to be completely level.

Two interchangeable mixing vessels are supplied with each machine to form a semi-continuous mixing operation. Double-planetary mixers can process applications that are wet (pastes and slurries) and dry (granulations and powder blends), including semi-solids (gels and dough-like materials).

The 100-gal mixers feature a CIP system that includes five ports with rotating spray nozzles directed at the gearbox, agitators, and vessel. The spray balls are piped to a central cleaning system manifold for single-point hookup. The reverse-lift design also enables raw material feeding equipment to be hard-piped to the vacuum hood.

Each mixer is controlled from a NEMA 4X stainless steel purged panel (Class I, Div 1, Group D). The fleet of 11 machines is explosion proof.
