It is crushed and crushed, and is mixed into a uniform state that is easily pumped by a sand pump. At this time, as described above, the case 1 also serves as an enclosure for mixing, and both stirring blades 10, 1
Although it depends on the inclination angle of 1, the flow of sludge 16 in a fluidized state caused by the stirring blades 10 and 11 in a radial direction from the center of the stirring blades 10 and 11 to the outer peripheral direction or at a right angle to the direction of the bottom soil 18 It also serves as a flow channel.
