This company has expanded its most advanced planetary mixer line, the PDDM (photo), to include larger working capacities up to 750 gal. The PDDM is a multi-agitator mixer featuring two planetary stirrer blades and two high-speed disperser shafts. Designed for highly viscous and highly filled applications, the hybrid system can quickly incorporate large amounts of dry ingredients into thick or sticky liquid, and apply intense shear to achieve a smooth and uniform consistency. The PDDM is rated for vacuum operation up to 29.5 in. Hg and includes a jacketed change-can vessel, sight and charge ports on the cover and an automated lift for raising or lowering the agitators. The mixer is usually supplied with a discharge system for fast and convenient transfer of the finished product. — Charles Ross and Son Co., Hauppauge, N.Y.
