Research and Application of New Scraper Device of Disc Magnetic Separator in Nanshan Mine
In order to improve the comprehensive recovery and utilization rate of magnetic minerals in tailings slurry,avoid resource waste and environmental pollution in Nanshan Mining Co.,Ltd.,aiming at the problems of tailings recovery efficiency decline,fast wear of scraper and disk surface,short service life and frequent replacement caused by the failure to adjust and compensate after the wear of the scraper of the exist-ing disc magnetic separator,an innovative research on the scraper was carried out.A new polyurethane ma-terial with high elasticity and high wear resistance is applied,and combined with the principle of screw drive,a new type of scraper device for disc magnetic separator with automatic compensation of wear was de-veloped.The field application results show that the new scraper solves the problems of incomplete unloading and rapid wear of the scraper of the disc magnetic separator,and has the value of popularization and applica-tion in similar mines.
