Magnetic hard rock and steel ball separation device

The invention relates to a magnetic hard rock and steel ball separating device which is of a concentrating table structure and comprises a transmission device, a rack and a bed surface, the bed surface is movably arranged on the rack, the upper end of the bed surface is connected with the transmission device, and the bed surface can be driven to reciprocate on the rack under the condition that the transmission device moves periodically; the whole bed surface is obliquely arranged around one corner of the lower end of the bed surface, a plurality of grooves are formed in the bed surface in the descending direction of the bed surface, and the bed surface is a shovel-shaped bed surface; a separation guide plate is obliquely and upwards arranged in the middle of the bottom end of the bed surface and can play a role in shunting, so that magnetic hard stones on the bed surface above the separation guide plate are prevented from falling into a steel ball blanking area; the width of the groove is 3-5 mm, and the dept
