Used for the pre-selection of low-grade magnetite and dry powder ore with a particle size of 0~16mm and a grade of 5%~20%, effectively improving the grinding feed grade and reducing beneficiation costs.
The design adopts a magnetic system with small pole pitch and multiple magnetic poles, increasing the number of magnetic system reversals to facilitate the discharge of impurities.
The 180° large wrap angle design effectively extends the length of the separation zone and improves the recovery rate of iron ore.
A simple material distribution structure allows for more convenient control of the grades of concentrate and tailings.
The cylinder liner is made of wear-resistant ceramic with a hardness of HRA ≥ 85, **capable of reaching HRA 92 or above**, and offers superior performance that is irreplaceable by other wear-resistant metal materials.
Using the principle that magnetic materials can be attracted by permanent magnets, a semi-circular magnetic system with a strong magnetic field is designed inside the drum through which the material flows. When the material passes through this magnetic field area, magnetic minerals are immediately captured by the powerful magnetic force and adhere to the surface of the drum's semi-circular magnetic system. As the magnetic materials are carried to the lower non-magnetic area, they fall under gravity into the concentrate outlet for discharge. Meanwhile, non-magnetic ores or ores with low iron content can freely pass through the magnetic field under gravity and flow to the tailings outlet for removal.
