The lignite material contains a certain amount of moisture. In order to increase the calorific value of the material and improve the comprehensive utilization value of its equipment, it needs to be dried first, and the lignite drying treatment generally uses a lignite dryer. The lignite dryer achieves the purpose of material precipitation and quality improvement, so how does the lignite dryer dry it?
The lignite dryer is generally a tumble dryer equipment. The equipment mainly uses the high-temperature hot air to contact the material to dry the lignite material. After drying, the lignite material generally has a moisture content of about 10%. , to improve the calorific value of lignite material. Working process: The lignite material enters the drum of the dryer through the conveyor. With the continuous rotation of the drum, the lignite material is continuously lifted and dropped, which increases the contact area between the material and the high-temperature hot air, and the lignite material evaporates quickly, reducing the drying time of the material.
