Double Planetary Mixers

The change-can Double Planetary Mixer (DPM) was a revolutionary invention introduced by ROSS. As its name implies, the DPM consists of two identical blades that move in a planetary motion, rotating on their own axes as they orbit a common axis. In only 36 revolutions around the vessel, the two blades pass through every point in the product zone, physically contacting the entire batch. Its ability to turnover thick, sticky or putty-like materials with great efficiency makes the DPM a standard workhorse in many industries. When mixing high viscosity products upwards of 2 million centipoise (cP), the blades impart a kneading action to the batch, smoothing out its consistency and breaking up any agglomerates.
