Non-metallic mineral product calcining equipment and process

The invention discloses non-metallic mineral product calcining equipment and process. The non-metallic mineral product calcining equipment comprises a calcining box and a plurality of supporting legs arranged at the lower end of the calcining box. A heating mechanism used for heating is arranged on the outer side of the calcining box. The outer side of the heating mechanism is wrapped with a protective shell. A feeding opening used for feeding is formed in the upper left end of the calcining box. A discharging opening used for discharging is formed in the right lower side of the calcining box. A guiding assembly matched with the discharging opening is arranged in the calcining box. The equipment is designed for overcoming the defects of an existing device, the discharging mode is improved, discharging is controlled in the mode that an upper bottom plate and a lower bottom plate are staggered and coincide, the diameter of the discharging opening is guaranteed, and the discharging speed is high. By arranging an
