A1
Abstract:
Disclosed in the present invention are a device for preparing an energy-saving material by combining dehydrated phosphogypsum and industrial slag, and a use method, comprising a crushing box, a first mixing hopper and a second mixing hopper. An insertion slot is provided in the top of the crushing box, and two first bearings are fixedly mounted on one side of an inner cavity of the crushing box. Crushing rollers are fixedly mounted on inner sides of both first bearings, and gears are fixedly mounted on the ends of the crushing rollers away from the first bearings. A protection box is fixedly mounted on one side of the crushing box; and a crushing motor is fixedly mounted on the inner side of the protection box. By means of mixing and crushing dehydrated phosphogypsum and industrial slag to prepare a novel energy-saving material, waste utilization of dehydrated phosphogypsum and industrial slag can be effectively performed, and preparation is convenient. Phosphogypsum can thus be effectively utilized, the utilization rate of phosphogypsum is improved, phosphogypsum surrounding a phosphating plant is effectively utilized, and thus the huge quantity of solid waste residues occupying land is reduced, encroachment on arable fields is reduced, and pollution of the surrounding environment is reduced.
