Abstract
With a slurry continuous pressure-feeding apparatus wherein normally three feed chambers alternatively operate to continuously pressure-feed the slurry, in the case of continuously pressure-feedingthe surry by using two feed chambers, the same amount of slurry as in the case of three feed chambers can be pressure-fed by operating an auxiliary slurry pump installed in parallel with a slurry pump. Some portions of piping systems maintained with the feed chambers are formed with bending pipes which absorb expansion or contraction of the piping systems due to thermal expansion of the piping systems and the fluidic pressure of a fluid flowing through the interiors of the pipes. A float formed in the form of a cylindrical body closely attachingly provided at both upper and lower ends thereof with bowl-shaped end plates, is inserted into the respective feed chambers.
