Wear resistant ceramic elbows are excellent alternatives to stainless steel pipes, cast stone pipes, and high chromium cast iron pipes in the field of wear resistance. They are widely used in industries such as power, mining, steel, coal, metallurgy, and cement to transport materials such as tailings, ash, sand, coal powder, and concentrate powder. Ceramic wear-resistant elbows have high wear resistance, corrosion resistance, and heat resistance, with a service life nearly dozens of times longer than ordinary pipelines. They are lightweight and easy to install, allowing enterprises to better reduce costs and save energy consumption.
Wear resistant ceramic elbows are not only used for ash removal, slag discharge pipes, powder feeding and returning pipes, and desulfurization pipelines in coal-fired power plants, but also widely used in the following industries:
Mining: coal slurry, coal washing mud, mine filling materials, and coal powder in the coal industry;
Metal mines: wear-resistant elbows for conveying concentrate and tailings;
Metallurgy: pipelines for coal injection and slag transportation in the blast furnaces of steel plants; CAO、 Zinc sand conveying pipeline, preferred wear-resistant elbows for conveying ferroalloys in steelmaking and refining outside the furnace;
Cement plant: raw material slurry conveying, coal powder conveying, elevator feeding, finished cement pneumatic conveying loading and unloading of rotary kiln wet production line, wear-resistant elbows for concrete conveying.
Chemical plant: Coal powder conveying pipeline, wear-resistant elbow for conveying raw materials such as silicon powder.
Wear resistant ceramic elbow is a material mainly composed of alumina (AL2O3), supplemented with other ingredients, and fired at a high temperature of 1700 degrees. The adhesive ceramic wear-resistant elbow is widely used in coal transportation, material transportation systems, powder production systems, ash discharge, dust removal systems and other mechanical equipment in enterprises such as thermal power, steel, smelting, machinery, coal, mining, chemical, cement, port and dock. Different types of products can be selected according to different needs.
