The sealed and purged gearbox assemblies are designed for sensitive applications requiring the tightest protection against contamination. The Ross 40-gallon Double Planetary Mixers are designed for sanitary formulations. Two rectangular planetary blades rotate on their own axes while they orbit the mix vessel on a common axis in order to move viscous fluids or wet granulations. The stainless steel 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 sanitary tri-clamp design. Atomizing spray nozzles are installed on dedicated ports for controlled and spill-free addition of liquid raw materials into the batch. Other optional features include:
- Flush discharge plugs or valves
- Covers for use with the portable mix vessels during transport
- Controls integrating the mixer with auxiliary equipment
