Introduction
The lignite is a mineral coal of minimum carbonificated degree. Because of its rich in volatile ingredients, so easy to burn and smoke. It is mainly used for power plant fuel, also may make the chemical raw materials, catalyst carrier, absorbent, sewage treatment and recycling metal, etc. In view of contains many impurities, lignite and other coal resources is same, when mined, after dressing chosen, and more high-quality coal can be got ,slime in the process of dressing with high moisture combustion and not easy burning then causing inconvenience and waste of resources utilization. Through the drying process, the lignite and coal slime will try to make water evaporation then can be used , reduce the waste, after drying can make briquettes used for cooking and heating, but also can be used as activated carbon sources, used in water treatment, recovery gold and extraction iodine.
Characteristics
Lignite dryer researched and developed by us is a new technology to dry lignite, has the following characteristics
1,Grasping the best entering temperature and discharging temperature to dry the lignite;
2,Studying the form of lifting plate for drying lignite;
3,Determine the evaporation strength to dry lignite;
4,Grasping the lignite drying and volatile loss situation;
5,Researching the grain-size influence for the lignite drying effects;
6,Studying the broken degree during the lignite drying process;
7,Researching get damp characteristics after lignite drying;
8,Researching the harmful substance content in the exhaust emission;
