METHOD AND APPARATUS FOR CONVEYING MATERIALS IN BULK BY LIQUID PRESSURE ABSTRACT OF THE DISCLOSURE A method for conveying materials in bulk by li- quid pressure carried out by an appropriate apparatus involves loading a material in bulk into a chamber through a loading pipe and then supplying liquid un- der pressure through a pipe for supplying liquid in the form of a downward annular flow, and discharging the material in bulk in an upward flow through a dis- charge pipe mounted to extend coaxially with, and inside the pipe for supplying liquid. A zone of recir- culation flows of liquid is formed in the chamber by swirling the annular flow to an extent determined by a ratio of the rotational component of velocity to the axial component of velocity at least equal to 0.4. The material in bulk is discharged in the zone of reoir- culation flows. For swirling the annular flow, an inlet port of the pipe for supplying liquid is located in the periphery thereof, and the axis of this port is off set with respect to the axis of the discharge pipe. The inlet and outlet ports of the pipes for ma- terial discharge and liquid supply, respectively, are located at predetermined level with respect to each other.
