Fote rotary drum dryer drying system for sawdust

This rotary dryer is a type of industrial dryer employed to reduce the moisture content of biomass materials like sawdust, wood shavings and coffee husk, by bringing them into direct contact with a heated gas. The dryer is capable of handling large quantity of raw materials to be further processed.

Utilization of lignite resources in China is relatively low, most are still used as a coal, and comprehensive utilization is not high. China in high-moisture lignite power technology is still using the traditional direct combustion method, inefficiency, poor utilization of equipment can reduce lignite moisture is the important means to improve the utilization of lignite. Therefore, coal drying experts Dongding dry with the actual situation, rotary drum dryer the development of the lignite drying dehydration equipment, equipped with a of lignite special large heat source, dry lignite security be guaranteed, to further reduce overall costs.

Lignite drying molding technology is divided into two drying and molding processes:

Machines and scraper conveyor belt conveyor lignite drying process: raw coal crushing 0-50mm and eventually enter the inside of the large-scale lignite dryer. Tilt rotation of the drum, the copy board wall by the drum so that the full cut fabric curtain lignite formation in thedrying cylinderbody to make contact with up to more than 500 ℃ high temperature hot air to exchange heat discharged into the nesting box after drying sealed nesting scraper conveyor, belt conveyor chute into, and ultimately into the silo. Coconut shell dryer.

Fully with the flue gas, the material residence time in the dryer in about 30 minutes, so the lignitegets dry. The system is equipped with a burner furnace of the Division I independent development, you can use the cheap brown coal as a heat source, so that resources can be more fully utilized wood chips dryer .
