Energy-saving magnetic separator for mineral separation

The utility model discloses an energy-saving magnetic separator for mineral separation. The device structurally comprises a shell, a charging opening, a controller, a feeding hopper, a motor, a driving gear, a first transmission belt, a driven gear, a permanent magnet roller, a scraper and an anti-blocking mechanism, the motor power-on output end drives the permanent magnet roller to rotate; the permanent magnetic roller drives the transmission gear to rotate; the second transmission belt drives the connecting gear to rotate; the connecting gear drives the driving bevel gear to rotate while rotating; the driving bevel gear is matched with the driven bevel gear to rotate; meanwhile, the driven bevel gear drives the cam to rotate; the T-shaped rod moves left and right under the combined action of the cam and the compression spring and drives the transmission block to move left and right at the same time, the transmission block drives the rotating plate to rotate left and right through the pull rod, and therefor
