Slurry-transporting facility and slurry transportation control method

摘要

A slurry-transporting facility provided with multiple series of pump devices, wherein efficient operation is made possible by limiting the stopping of slurry supply to the transport destination during switching of pump device use between the various series. The slurry-transporting facility is provided with: pipes (11) from a supply tank (1) branching into multiple series; transport pumps (12) provided on the respective pipes (11); first valves (13) on the upstream side of the transport pumps (12); second valves (14) on the downstream side of the transport pumps (12); and an integrated pipe (16) formed by merging the various pipes (11) at a specified position and to which an LT heater (2) is connected. The integrated piping (16) is provided with a third valve (17) for controlling the transport of an ore slurry to the LT heater (2) and a pressure gauge (18) for measuring the pressure inside the integrated pipe (16). The pipe (11) of each series is provided with a pressure gauge (20) at a position that is downstream from the transport pump (12) and upstream from the second valve (14).
