 LJK Overbelt Magnetic Iron Ore SeparatorOverview 

 
The LJK Series represents a specialized intelligent magnetic iron ore separator designed specifically for handling magnetic materials. Comprising main and auxiliary magnetic drums, frame structure, discharge belt, metal detector, and control cabinet, this system utilizes unique magnetic field arrangement technology. When triggered by high-sensitivity metal detection, it generates instantaneous strong excitation followed by multi-stage separation, effectively addressing the common problem of high ore carry-over in conventional separators.
 
This advanced overbelt magnetic separator is particularly suitable for iron and manganese ore processing lines, where it accurately removes harmful ferrous objects (0.1-40kg) including plates and bars that could damage downstream equipment. Its intelligent operation ensures minimal product loss while maintaining maximum protection for processing machinery.
