With the rapid development of social economy and ceramic industry, ceramic industry waste is increasing day by day. It not only puts great pressure on the urban environment, but also limits the development of urban economy and the sustainable development of the ceramic industry. Therefore, the treatment and utilization of ceramic industry waste Very important. A large amount of tile waste is no longer a problem that can be solved simply by landfilling. How to turn waste into treasure and waste into resources has become a top priority. So, what can be done with tile waste? What equipment is used for grinding tile waste? Today, Guilin Hongcheng, a manufacturer of waste tile grinding mills, will introduce them to you respectively.

Porcelain tiles and thick glazed tiles are processed into mirror-like, smooth and delicate polished tiles after a series of deep processing such as scraping and thickness setting, grinding and polishing, and edge grinding and chamfering, resulting in a large amount of tile debris. The grinding and polishing process usually removes 0.5-0.7 mm surface layer from the surface of the brick, sometimes even as high as 1-2 mm, then the production of 1 square meter of polished brick will form about 1.5 kg of brick debris, if the annual output of 400,000 square meters of polished brick Taking the polishing production line as an example, about 8.4 million tons of polished brick waste slag is produced every year. So, what can be done with tile waste?
1. Used to produce ceramic tiles: At present, breakthroughs have been made in the research on the recycling of industrial waste produced by ceramic factories themselves. The discarded muddy water can be added to the ingredients of tiles and used for tile blanks after recycling, picking out sundries, and removing iron. For waste products such as waste products, waste saggers and waste kiln furniture that have been fired at high temperature, re-grinding can also be used to grind them, and then add them to the ingredients of ceramic tiles or western-style tiles in a proportion of 3w% for ceramic tiles. Drying, crushing and sieving of waste billets and waste mud are used as raw materials for archaized bricks. There is no cost of raw materials, and the cost of powder manufacturing is extremely low. Combining the chemical composition and characteristics of waste billets and mud, it is also possible to develop and produce artistic bricks with different styles. It is environmentally friendly and reduces the cost of ceramic products.
2. For the production of porous ceramics: After years of hard work, some researchers in our country have developed a process for producing porous ceramics using waste materials from ceramic factories. This method adopts the solid waste in the general ceramic factory, which can be divided into waste material, waste mud, waste porcelain, waste residue, sediment and dust according to the form. Firstly, the solid waste is processed into a certain mesh of powder through a waste tile mill, and the ingredients are filled with soil powder, porcelain powder as aggregate, fly ash and glaze powder as foaming base materials, and hair Foaming agent coal powder and foaming aid boric acid, sodium nitrate, etc. When batching, first mix the foam base material, foaming agent and foam aid evenly, and pass through a 100-mesh sieve three times, then add fillers and aggregates, mix evenly, spread them evenly in a stainless steel mold, and burn them in an electric furnace. system. The porous ceramics developed by this method have low bulk density and high strength, which are suitable for new wall materials and can also be used to manufacture square permeable bricks.
3. Used in the preparation of cement: Using ceramic tile waste as cheap raw material for cement production and realizing the organic combination of the two major industries of ceramics and cement will undoubtedly produce great social and economic benefits. It can not only process a large amount of tile waste, but also provide a new raw material for cement industry production. Ceramic waste has good grindability, and the addition of ceramic waste will not affect the grinding effect, on the contrary, it will increase the specific surface area of cement to a certain extent. With the increase of the dosage, the strength of cement decreases, the water demand increases, and the setting time becomes longer, but as long as the appropriate proportion is selected, ordinary Portland cement with higher strength can be produced. Since tile waste is mainly composed of silicate minerals and has certain activity, as long as it is properly treated before use, it can be used as cement admixture in large quantities in the cement industry to produce qualified high-strength cement.
4. Used to develop solid concrete materials: Solid waste concrete (SWC for short) is an environmentally friendly material with solid waste as the main raw material and has the properties of ordinary concrete. It can be used to manufacture building wall materials, and can also be used in various Ground paving material for roads and other construction works. It is technically feasible to use SWC material made of tile waste to produce non-fired road square bricks. After repeated tests, its performance indicators meet the requirements of national standard excellent products. It not only disposes of waste materials from ceramic factories, but also saves resources and meets the requirements of national environmental protection. It is a promising green building material product.
There are many types of tile waste raw materials, and the moisture content is different. In order to ensure the consistency of the formula before and after raw material grinding, the vertical mill has become an ideal equipment for tile waste grinding.
The vertical waste tile mill produced by Guilin Hongcheng can be dried by hot air inside the mill, which solves the problem that the raw material has a high moisture content and cannot be milled. The grinding principle of Hongcheng waste tile mill belongs to "material bed grinding", or "material bed extrusion grinding". The advantages of material bed extrusion grinding are more useful work, high mechanical efficiency and less wear. It avoids the large energy consumption of large materials in the crushing stage of the ball mill, greatly shortens the grinding process time of materials, greatly reduces the energy consumption of turning waste into treasure, and thus achieves energy saving in the stage of waste utilization. And this process is easy to realize the automation of the raw material processing process. From feeding to discharging and the materials of various formulas can be digitally controlled by computer programming, etc., and each key part has monitoring image points. It is a new high-efficiency and energy-saving ceramic raw material grinding process. It solves the problem of huge energy consumption in the traditional ceramic production process, reduces the energy consumption of ceramic tile waste grinding, and improves production efficiency. It is of great significance to the development of the entire ceramic industry.
