Slag dryer is a specialized mechanical equipment used for drying slag, widely used in industries such as building materials, metallurgy, chemical, and cement. The main function of a slag dryer is to dry slag containing a large amount of moisture through high-temperature heating, reducing its moisture content for subsequent processing and utilization.

Working principle

Slag dryer usually adopts a rotary design, mainly composed of a rotary cylinder, induced draft equipment, high-speed dispersing equipment, lifting plate and other components. Slag is fed into the hopper through a belt conveyor and then enters the feeding end of the dryer through a feeding pipe. In the rotary cylinder, the material moves forward under the action of gravity and rotation, and is repeatedly picked up by the plate, forming a uniform curtain that fully contacts with the hot air flow, thus achieving the purpose of drying.

Performance characteristics

The slag dryer has the following performance characteristics:

Large processing capacity: capable of efficiently handling large amounts of materials.

High thermal efficiency: adopting a new transmission device, the energy-saving effect is significant, saving about 20% energy compared to general dryers.

Environmental protection: It has good dust removal effect and meets environmental standards.

Durable: Using new wear-resistant materials to extend the service life of equipment.

Application area 

Slag dryer is widely used in industries such as building materials, metallurgy, chemical industry, and cement, for drying materials such as slag, limestone, coal powder, etc. Dried slag can be used to produce slag cement, slag powder and other products, effectively saving energy consumption.
