The LDP 8000 Pressure Concept™ is a Batch Medium Phase Pressure System at low to medium viscosity. The pressure concept conveying system is generally used for different applications, including conveying the medium to high density, semi-abrasive, fluidizable materials that are difficult to convey through typical system. It is used to process coffee beans, powdered chocolate, and ground limestone, calcium carbonate, iron oxide, alumina, and cement and silica flour. The conveying velocities are about 1500 feet per minute (7.5 m/sec) and the estimated conveying pressure is 15 PSIG (1 barg). Pressure vessel is used to feed the material in the conveying line and the DC-5 Air Saver technology to reduce and optimize the low pressure air supply. The air is supplied by the low pressure positive displacement blower.
