Apparatus for continuous pressure feeding of slurry
 Slurry consisting of water and solid material is fed to fill a plurality of supply chambers arranged in parallel to each other, by the action of slurry pump. The filled slurry is forced to a transferring pipe by the liquid pressure of a high pressure driving liquid pump. A float is positioned on an interface between the slurry and driving liquid within the supply chamber. When a sensor for detecting the position of the float is inoperative due to an external turbulence or the like, a command signal is applied to selected valves in response to a period of time set in a timer.
