The present invention is a method and apparatus for drying sludge containing fine particles, while supplying hot air and microwave electromagnetic waves into a drum inner space while rotating a rotating body composed of a plurality of sludge conveying partitions in a sealed and inclined drum, Sludge is supplied to the inlet of the drum at a constant rate, is moved by the partition of the rotating body to the high position on the drum wall, and is heated by the microwave while falling to the low position by gravity, and by the partition at the lower position As it rotates through the drum wall and goes back to a higher position, it eventually reaches the outlet of the drum, and the evaporated water moves to the outlet of the drum with the hot air, and the completely dried sludge reaches the outlet of the drum. Method and apparatus for drying sludge fine particles to allow fine particles to be discharged out of drum The.n n n n Slurry, Sludge, Fine Particle, Microwave Electromagnetic Wave, Silicon Carbide, Wafer Cutting Process |
