PROBLEM TO BE SOLVED: To easily increase a contact area of a magnetic force belt and a solution to be processed containing a magnetic substance sludge and to efficiently recover the magnetic substance sludge by adsorbing and recovering the magnetic substance sludge to the magnetic force belt stretched between an upper pulley and a lower pulley. SOLUTION: When a solution 16 to be processed containing a magnetic substance sludge is fed from a solution to be processed feeding pork 20 into a first recovering tank 18, the magnetic substance sludge is floated and dispersed in the solution 16 to be processed by a water flow formed by a fan 40. This magnetic substance sludge is adsorbed to a surface of a first magnetic force belt 24 by a magnetic force and is recovered from the solution 16 to be processed. When the magnetic substance sludge passing through a squeezing roller 26 arrives at a contact portion of a first scraping plate 28 and a first magnetic force belt 24, the magnetic substance sludge is scraped by the first magnetic force belt 24 at a tip end of the first scraping plate 28, and is conveyed on the first scraping plate 28 and is discharged from a magnetic substance sludge discharge port 12a to the outside of a housing 12. |
