With the development of the large-scale construction and industrialization in the country, lignite is the power in the chemical industry, which is the resource that needs to make full use of. Lignite is mainly used as fuel in power plant, but also can be used as chemical raw material, catalyst supports, adsorbents, sewage purification and recovery of metal. It can also be used as a household fuel, industrial fuel as heat source.
Lignite is a kind of mineral coal with minimum coalification degree. Because it is rich in volatile elements, it is easy to be burnt and generate smoke. It is mainly used as power plant fuel, chemical raw material, catalyst supports, adsorbents, sewage purification and recovery of metal, etc. The dried lignite can be made as coal bricks used for cooking and heating, which can also be used as a source of activated carbon used for water treatment, recovery of gold and iodine extraction. Lignite dryer can realize continuous, industrial and automatic operation. It can be used for drying fly ash, coke, coal as well as other granular, paste and powder materials. Lignite dryer can guarantee that the quality of coal slime and lignite is unchanged after the drying process, which can dewater the coal slime to the moisture content below 13%, so as to improve the combustion efficiency. Therefore, lignite dryer can make full use of the coal resources and reduce the emission concentration, so as to achieve energy-saving emission reduction and environmental protection objectives.
In the design of lignite dryer, Fote Machinery has taken full consideration of the material properties of lignite drying machine, in view of the lignite characteristics with high water content, special design is done in the internal structure of barrel body, so as to further strengthen the crushing proof of unity block materials. It not only improves the thermal efficiency, but also effectively avoids the phenomenon of excessive drying of coal which is easily generated in the drying process. Fote Machinery has produced a series of dryer equipment, such as vertical drying machine, band drying machine, industrial drying machine, chain plate drying machine, mine drying machine, coal slime dryer, rotary dryer and other auxiliary drying equipment.
