Lignite dryer: conventional drying method commonly used centrifugal mechanical dewatering equipment is expensive dryer, low productivity, low margin dehydration, usually only one precipitation 10%. The remaining 15 --- 20% moisture content. Nanyang mechanical H type rotary dryer lignite, lignite took the first break and then heat-dried dispersion of new technology, the dried material to achieve a continuous, industrialization and automation. After drying lignite sludge treatment process water wet lignite from 25% to 30% to 13% less coal is used as fuel, and improve coal washing process, with good economic, social and environmental benefits. Rotary lignite dryer, to ensure the quality of the dried lignite dryer equipment unchanged, four low temperature drying process, the lignite water evaporation to below 13% moisture content. After drying zone level at 400 ℃ high temperature and high humidity state to remove most of the moisture dryer manufacturers to ensure that the chemical composition of lignite does not change and difficult to burn; secondary drying zone temperature 300 ℃, temperature strength by the wind yield In addition to the water drum dryer ensure lignite no coking; drying zone three indoor temperature 120 ℃ -210 ℃, the use of the drum crushing device, repeatedly hit, broken materials, downstream drying; drying area for four high exhaust area, room temperature 60 ℃ -80 ℃, cited by negative pressure air system low temperature hot air exclude moisture. 1. The regular maintenance cleaning brush clean surroundings and return heat filter. 2. Always check the steam inlet pipe and fittings. Always check the operating system and heater lines, identify problems and should be immediately removed. 3. Often the drive section lubricating the bearings. 4. Machine maintenance once every six months, major maintenance once a year. 5. In order to improve efficiency, increase ventilation capacity, frequently clean up, clean the air vents of the debris line the railings, all dryer door shut. 6. Always open the trap discharge water to avoid cold water to stay in the radiator, causing the temperature does not rise up.
