Abstract

PURPOSE: To reduce friction on a movable pipe even if the specific gravity of solids in slurry is high, by connecting a return water pipe to the rear of the movable pipe through a connecting pipe and providing the connecting pipe with an orifice.
CONSTITUTION: When the solids in slurry have high specific gravity as sand and iron ore, the degree of opening of a valve 16 is lowered to reduce the quantity of returned water to be conducted to the rear of a movable pipe 9 through a connecting pipe 15 and the degree of opening ΔL of the discharge port 7a of a slurry tank 7 is heightened. For that reason, the velocity of flow through the discharge port 7a is decreased. This results in greatly reducing friction on the movable pipe 9 and at the discharge port 7a.
