Advantage of the valuable resources of lignite, turning waste into treasure, not only can generate considerable economic benefits. Dryer production line through a dedicated lignite, to ensure that the premise of constant dry lignite quality, reducing the moisture content of lignite to improve the calorific value of lignite, to enhance the combustion efficiency of coal resources more fully utilized. Dong Ding lignite dryer system is dry, oxygen-free state to solve the dry lignite security issues, a Division I of the patented product configuration, burner furnace, the direct use of lignite as a fuel, so that further reduce the cost. 
 Lignite dryer structure composed of 
 The ★ raw material crushing and feeding system: selection of a screening crusher broken chunk of raw materials into the particle size ≤ 20mm, and vibrating feeder with the one or more belt conveyor, seal scraper conveyor or screw conveyor to achieve uniform, continuous feed, close to the dryer feed inlet device using heat and seal the good performance of the equipment. 
 The ★ burning heating systems: selection of lignite drying burner stove, and the use of lignite as a fuel and to ensure that the high temperature thermal medium to provide a stable drying system. 
 ★ dry and dehydrated systems: selection of sealing the feed box, propeller, tumble dryer for more than a return, the row of bins and other equipment to complete the quality of high-moisture materials and high temperature heat medium heat exchange. 
 ★ environmental protection dust removal system: selection of the cyclone, screw conveyor, or star-shaped air lock, as quoted in the fine particles in the fans, wet scrubber equipment recycle dry products, while achieving exhaust emissions standards. 
 ★ distribution monitoring and control systems: power distribution device selection, monitoring and control console, industrial TV monitoring system, in-place box, electric actuators and other electrical equipment to achieve the drying system is centralized or local automatic control. 
 ★ product transport system: the selection of one or more tape transports dry product transportation to a user specified location, which is close to the dryer feed the mouth of the equipment using heat and seal the good performance of the transportation equipment (the feed material temperature about 70 ℃ ). 
 Dongding lignite dryer features of the process 
 Dryer design to fully consider the nature of the dry feed, specially designed for lignite high water content in the cylinder on the internal structure, further strengthen the anti-fragmentation of the unity block material, not only to improve the thermal efficiency and effective to avoid excessive dryness of the coal in the dryer. The lignite drying dehydration, which can effectively improve the heat index lignite and Chu shipment performance, so that the indicators meet the requirements of commodities steam coal has obvious economic, environmental and social benefits.
