Problems solved by technology

[0003] Both melting and sintering glass-ceramic production consume a lot of energy, but if the heat treatment process is not well controlled in the glass-ceramic production, the crystallized product will often burst and deform and become waste.
For these waste products, at present, they are mainly crushed to a certain particle size, and then added to the furnace for secondary melting together with the batch materials, which requires a large amount of energy again.

Embodiment 1

[0026] Example 1: A recycling method for glass-ceramic materials, using the waste produced in the production of glass-ceramics as the main raw material, through crushing, sieving, grading, adding binder, mixing and milling, compression molding, drying, hot air Hardening and other processes are carried out for regeneration treatment to obtain recycled glass-ceramic products. The specific process steps are as follows:

[0027] The chemical composition range of glass-ceramic waste is: SiO 2 40-60%, CaO 10-20%, Al 2 o 3 5-20%, MgO 3-7%, CaF 2 3-10%, Fe 2 o 3 +FeO 5-12%, REO 0.1-2%, R 2 O 2-5%, Cr 2 o 3 0.1-0.5%.

[0028] 1) Remove the surface dirt from the large pieces of waste generated in the production of glass-ceramic, and put them into the jaw crusher or roller crusher for crushing after coarse crushing. The crushed materials are conveyed to the vibrating screen by the belt conveyor. points, and screen out the granular material with a particle size below 3mm. The ...

Embodiment 2

[0038] Embodiment 2: A kind of recycling of glass-ceramic material and its manufacturing method, its technological steps are as follows:

[0039] 1) Remove the surface dirt from the large pieces of waste generated in the production of glass-ceramic, and put them into the jaw crusher or roller crusher for crushing after coarse crushing. The crushed materials are conveyed to the vibrating screen by the belt conveyor. points, and screen out the granular material with a particle size below 3mm. The granular material with a particle size greater than or equal to 3mm is returned to the roller machine by the belt conveyor to continue crushing until the particle size is less than or equal to 3mm.

[0040] 2) The finely broken granular material is transported to the vibrating screen through the belt conveyor, and after being sieved by the vibrating screen, three different particle sizes of 0.1-1mm, 1-2mm, and 2-3mm are obtained, and then the sieved The residue is processed into a fine...

Abstract

The invention relates to a recycling method of a glass ceramic material. Waste generated in glass ceramic production is used as a main raw material, and recycling treatment is performed through the processes including smashing, screening, grading, binding agent adding, mixing and grinding, press-forming, drying, hot air hardening and the like to obtain a recycled glass ceramic product. Due to the fact that the waste produced in glass ceramic production is used as the main raw material, the energy consumption is reduced, stored waste glass ceramic materials can also be decreased, and environmental pollution is reduced. The production process is simple, the energy consumption is low, the production cost can be effectively reduced, different batches of products are good in reproducibility, and the recycling method is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a method for manufacturing glass-ceramics, in particular to a method for manufacturing glass-ceramics by using waste produced in the production of glass-ceramics, which belongs to the comprehensive utilization of industrial waste. Background technique [0002] Glass-ceramics is a polycrystalline solid material containing a large number of crystal phases and glass phases obtained by controlling the crystallization of a specific composition of basic glass during heat treatment. It has good thermal and chemical stability, high mechanical strength and hardness, good acid and alkali corrosion resistance, etc. [0003] Both melting and sintering glass-ceramic production consume a lot of energy, but if the heat treatment process is not well controlled in the glass-ceramic production, the crystallized product will often burst and deform and become waste. For these waste products, at present, they are mainly crushed to a certain partic...
