Abstract: The invention discloses high-strength glass-ceramic-based lightweight aggregates and the preparation method thereof. The mass ratio of raw material components is 50-70 parts of engineering muck, 20-40 parts of glass, 3-7 parts of calcium carbonate, 3-7 parts of magnesium oxide, and 2-10 parts of a nucleating agent; the nucleating agent is at least one of calcium fluoride, titanium dioxide, and chromium oxide. After crushing, mixing, and granulating, spherical particles with a particle size of 10-12 mm are formed; and then the product can be obtained after drying, sintering, and cooling. The obtained lightweight aggregate from the invention has a diopside matrix which provides high strength and a low water absorption rate at low densities. Moreover, waste glass and engineering muck could be utilized with high value.

Abstract: Plants and methods recover spent refractory material and comprise at least one receiving area for said refractory material, at least one material sieving area, at least one magnetic separation area, and at least one sorting area. Said receiving area communicates with a first sieving area divides said refractory material in at least two fractions based on sizes of said refractory material. A second sieving area divides a fine fraction into at least two sub-fractions.
