Countercurrent magnetic separator,
High strength steel tie rod are steel structural members made of carbon structural steel and alloy steel, processed by machining, heat treatment and surface anti-corrosion treatment, supplemented by adjusting sleeves, lock and joints etc. The steel tie rod are important components of steel structures for construction of giant, large span buildings and ship docks. They are mainly used for prestressed parts and large span buildings in construction projects. While the strength of the product is improved, but the plasticity index is not reduced, which satisfies the principle of using the same amount of strength in the architectural design. The tie rods, tie bars, tension rods and tension bars steel grades are specified as grade 460, grade 520, grade 550, grade 650, grade 785, grade 830, grade 930, grade 1080 etc.

The direction of the ore is opposite to the direction of rotation of the cylinder 1 or the direction of movement of the magnetic product. The slurry is directly fed to the ore box 3 under the magnetic system of the circle 1. The non-magnetic ore particles and the magnetically weak ore particles are discharged from the tailings hole on the bottom plate below the left edge of the magnetic system, and the magnetic ore particles are reversed with the cylinder. The direction is taken to the concentrate end and discharged into the concentrate tank. This magnetic separator is suitable for rough selection and sweeping of fine-grained ferromagnetic minerals with a particle size of less than 0.6 mm. This is because the tailings discharge is far from the mine end. The selection time is longer and the recovery rate is higher, while the concentrate discharge end is closer to the mine mouth and the magnetic turnover effect is poor, so the concentrate grade is lower. The countercurrent type magnetic separator is not suitable for processing coarse ore. Because of the coarse particle size, the ore particles are easily deposited to block the sorting space.
