To provide a magnet separator configured such that reduction of recovery performance of a magnetic sludge or a failure of a device is difficult to occur even when a content of a magnetic sludge in liquid to be treated increases.SOLUTION: An outer circumferential surface of a magnetic drum is partially immersed in a flow of magnetic sludge-containing liquid to be treated. A removing mechanism removes a magnetic sludge on the outer circumferential surface of the magnetic drum from the outer circumferential surface of the magnetic drum. A magnetic sludge-containing information acquisition device acquires magnetic sludge-containing information regarding a content of a magnetic sludge contained in the liquid. A control device changes magnetic sludge removing performance of the magnetic drum in accordance with the sludge-containing information acquired by the magnetic sludge-containing information acquisition device. A circumferential velocity of the magnetic drum is opposite to a flowing direction of the liquid to be treated.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。マグネットドラムの周速方向が、被処理液の流れの方向と反対である。【選択図】図１
