Dense Phase Pressure Conveying:
Dense phase conveying is a widely known as plug flow systems which is non-suspension flow. The product is filled in a pressure vessel, which is then pressurized with the air or gas to be used for conveying. Once a pre-set pressure is reached inside the vessel, the bottom discharge valve opens and the material is conveyed to the destination. The material to air ratios is higher in dense phase conveying in the range of 20 to 100 kg/kg of air. Dense phase conveying uses compressed air and requires an air compressor. Dense phase conveying is used for high capacity and long distance conveying. Dense phase conveying employs the pressure vessel with valves and instrumentation which is controlled through PLC based control panel.
