Abstract
In transporting solid material of a wide particle size distribution ranging from small to large size particles, a liquid is added to the solid material as a transporting medium to convert the solid material into a slurry to be hydraulically transported. The slurry that has performed the function of transporting the solid material is passed through a water removing device and a solid-liquid separating device to produce a suspension which is stored in a heavy medium tank and returned, after adjusting the concentration of the solid material therein, to the starting point of transportation so that the suspension can be recycled for use as a heavy transporting medium.
