[0027] Working principle: When in use, the bearing steel sand to be dried is poured into the inside of the feed hopper 7, and the motor 1 8 drives the rotating shaft 4 to rotate, so that the rotating shaft 4 drives the auger plate 5 to rotate, and the rotation of the auger plate 5 transports the bearing steel sand to the inside of the cylinder body 1; at the same time, through the operation of the electromagnetic heating coil 2, the alloy steel support plate 9 and the bearing steel sand are heated, so that the bearing steel sand is dried.
