Comb tooth separator is composed of decelerating motor, box, magnetic roller, scraping board and other parts. The magnetic ring of the magnetic roller is arranged in comb shape. The reducer motor drives the magnetic roller to make circular motion. After the coolant containing powdered magnetic absorption impurities enters the box, the impurities are adsorbed to the outer wall of the magnetic ring, separated by the stainless steel plate (copper plate), the liquid containing impurities is drained, and finally the impurities are scraped into the pollution collection box by the scraping board.
The device is especially suitable for the treatment of grinding machine coolant with large flow rate and many impurities. Such as roll grinding machine, steel waste water purification, bearing grinding line, etc.
