Fly ash drying system works as follows: wet fly ash from the feeding device into the inner three-cylinder, to achieve downstream drying, fly ash in the inner constantly took a copy board, scattered spiral travels type heat exchange, and the other end to the inner movement of materials into the middle, countercurrent drying, the material is repeated constantly in the middle Yang Jin, was traveling way to step back two steps forward, both fully absorb the material in the middle inner cylinder the heat, and absorbs heat the middle of the drum, and prolong the drying time, the best material in this dry state. The other end of the line to the middle of material fall into the outer, material rectangular multi-loop mode of travel in the outer drum, to the drying effect of the material in the hot air exhaust fast marching drum role of new lignite dryer, did not reach the drying effect of the wet material due to weight and not fast marching, copy the material in this rectangular plate fully dry, so as to achieve the drying effect Dingwang machinery lignite dryer to complete the drying process. 1, material moisture content after drying is greater than a predetermined value, which is a control method to eliminate the production capacity of the dryer, to increase or reduce the supply of heat. 2, rolling ring on the barrel swing operation, the reason is female connector side rolling circle without clamping plate to make the elimination method is to use rolling circle and female connector and clamp properly maintain uniform lignite dryer equipment, prevent tight and prone to accidents. 3, the large gear meshing with the pinion gear of the gap is destroyed, the reason is a. Tug wear b. Gear wheel wear c. Pinion wear their elimination method is turning or replaced as wear, or may be installed in pairs opposite update . 4, whole body vibration, the reason is a tug device and dock connector is damaged, the elimination method is correct tightening joints, it is in the correct position;.. B rolling ring flank wear, the elimination method is based on the degree of wear Toru, to roll turning circle or replaced. lignite drying machine production line, Dingwang machinery (certified), Hanzhong lignite dryer provided by Wang Ding Machinery Co., Ltd., Henan Province.
