A slag dryer, also known as a slag dryer, is a rotary drying device designed specifically for processing wet materials such as slag, carbide slag, limestone, clay, river sand, quartz sand, and slag. Its core structure consists of a rotating drum, an induced draft device, a high-speed disintegration device, a material lifting plate, a self-cleaning device, a transmission system, a conveying device, a hot air device, a speed reducer, a support device, and a sealing device. During operation, the inclined drum rotates, dispersing the material by gravity. The material then dries by fully contacting the hot air through countercurrent or cocurrent flow. The equipment's multi-combination lifting device significantly enhances heat transfer efficiency, reaching 80%-90%, while reducing coal consumption by approximately 20%.
Core Applications of Dried Slag
Cement Production Raw Material: Dried slag can be used as a cement admixture or concrete admixture, replacing part of cement clinker and effectively reducing production costs. Slag cement made from it exhibits excellent corrosion and heat resistance, making it particularly suitable for applications requiring specialized material properties, such as marine engineering and chemical equipment.
Road Construction Material: Dried slag can be used in roadbed paving or as an additive to asphalt mixtures, enhancing the compressive strength and durability of roads. Furthermore, its porous structure provides excellent thermal and sound insulation, making it suitable for use in the production of new building materials such as lightweight partition boards.
Glass Fiber and Ceramic Product Raw Material: Slag can be processed through melting and drawing to produce glass fiber, which is widely used in insulation materials and reinforced plastics. High-temperature firing can also produce ceramic products such as bricks and tiles, achieving high-value resource utilization.
Environmental and Agricultural Applications: Slag powder has strong adsorption properties and can be used in wastewater treatment to help reduce heavy metal pollution. In agriculture, slag powder can provide trace elements such as silicon and calcium to crops, promoting their growth and development.
Through efficient drying, slag dryers transform industrial waste into a high-quality resource that can be used in a variety of fields. This not only solves the environmental problem of waste accumulation but also creates considerable economic value.
