Ross Double Planetary Mixers and Discharge Systems are ideal for quick processing of non-flowing viscous mixtures. Turnkey processes utilizing the change-can mixer and discharge platen routinely benefit from shorter cycle times and lower operating costs compared to conventional horizontal sigma blade mixers and kneader extruders. Cleaning and changeover procedures are very operator-friendly: a hydraulic lift raises and lowers the agitators in/out of the mix vessel, enabling full access; multiple interchangeable vessels may be used for semi-continuous operation or dedicated to specific formulations to reduce cleaning frequency; and very importantly, the discharge operation thoroughly wipes down the vessel sidewalls leaving only a thin layer of product on the bottom to be cleaned out manually.
