Electrothermal blasting drying box for raw material treatment in ore detection process

The invention discloses an electrothermal blasting drying box for raw material treatment in an ore detection process and mainly relates to the field of ore detection. The electrothermal blasting drying box comprises an equipment main body. A plurality of limiting rods are arranged in a work cavity. A plurality of bearing frames are slidably arranged on the limiting rods and are provided with a holding plate. A cavity located on one side of the work cavity is formed in the equipment main body. A plurality of screws are rotationally arranged in the cavity, and the number of the screws is the same as that of the bearing frames. One bearing frame corresponds to one screw. Each bearing frame is connected with the corresponding screw through a sliding plate. The screws penetrate through the sliding plates and are in threaded connection with the sliding plates. A plurality of sliding grooves communicating with the cavity are formed in one side of the work cavity. The sliding plates are slidably connected with the sl
