Ross planetary mixers are now offered with newly improved sealed and purged gearbox assemblies for sensitive applications requiring the tightest protection against contamination. Pictured are 40-gal double planetary mixers designed for high-precision formulations. Two rectangular planetary blades rotate on their own axes, while they orbit the mix vessel on a common axis. This mixing action is ideal for moving viscous fluids or wet granulations. The stainless steel heavy-duty sealed gearbox housing includes a sloped cover to prevent contamination and pooling of condensed liquids. Solvent vapors and airborne particles are likewise prevented from entering the purged gearbox. These mixers also feature a gable-roofed bonnet to avoid dust or water collection. All ports and connections are tri-clamp design. Atomizing spray nozzles are installed on dedicated ports for controlled and spill-free addition of liquid raw materials into the batch.
