Used in conjunction with Ross planetary mixers and multi-shaft mixers, the Ross discharge system with electronic pressure control includes a platen that is lowered hydraulically into the mix vessel. The platen is fitted with an O-ring that rides against the vessel wall as the platen pushes down on the high-viscosity batch. Product is forced out through 1 or more outlet valves located on the vessel or on the platen. Interfaced to a PLC-based control panel, the system features a cylinder-mounted linear transmitter for the indication of platen position.
