High wear resistance barrel table adopts wear-resistant ceramic, hardness HRA≥85, high can reach HRA92 or above, and other wear-resistant metal materials have irreplaceable superior performance grade control simple distribution structure, can more conveniently control the grade of fine tailings, improve the recovery rate 180° large wrap angle design, effectively extend the length of the sorting area, improve the iron ore recovery rate and promote debris discharge. The magnetic pole magnetic system design increases the number of magnetic system flips and promotes debris discharge. Using the principle that magnetic substances can be attracted by permanent magnets, a semicircular magnetic system with a large magnetic field is designed in a drum flowing through the physics department. When the material flows through this magnetic field region, the magnetic ore is captured by the large magnetic force and adsorbed on the surface of the drum of the semicircular magnetic system. When the magnetic material is brought to the lower non-magnetic area, it falls to the concentrate port under the action of gravity and is discharged. Non-magnetic ores or ores with lower iron grades can freely flow to the tailings port through a magnetic field under the action of gravity
