To provide a magnet separator where the reduction of the recovery performance of magnetic sludge and the inconvenience of a device are hardly caused even when the content of the magnetic sludge in a liquid to be treated is increased.SOLUTION: In a magnet separator,: a part of the outer peripheral surface of a magnet drum is immersed in the stream of a liquid to be treated containing magnetic sludge; a removal mechanism removes the magnetic sludge on the outer peripheral surface of the magnet drum from the outer peripheral surface of the magnet drum; a magnetic sludge content information acquisition device acquires magnetic sludge content information on the content of the magnetic sludge contained in the liquid to be treated; and the controlling device varies the removal capacity of the magnetic sludge by the magnet drum in accordance with the magnetic sludge content information acquired by the magnetic sludge content information acquisition device.SELECTED DRAWING: Figure 1 【課題】被処理液中の磁性スラッジの含有量が増大しても、磁性スラッジの回収性能の低下や、装置の不具合が生じにくいマグネットセパレータを提供する。【解決手段】磁性スラッジを含有する被処理液の流れに、マグネットドラムの外周面の一部が浸漬されていり。除去機構が、マグネットドラムの外周面上の磁性スラッジをマグネットドラムの外周面から除去する。磁性スラッジ含有情報取得装置が、被処理液に含有されている磁性スラッジの含有量に関わる磁性スラッジ含有情報を取得する。磁性スラッジ含有情報取得装置で取得された磁性スラッジ含有情報に応じて、制御装置が、マグネットドラムによる磁性スラッジの除去能力を変化させる。【選択図】図１
