【Application】:Widely used for drying all kinds of coal, lignite, carbon coal, including anthracite, lean coal and poor lean coal, lean coal, coking coal, fat coal, air fertilizer coal, gas coal, etc.
Coal drum dryer is mainly composed of hot blast stove, belt feeding machine, drum dryer, belt discharging machine, induced draft fan, cyclone dust collector, bag filter (or wet dust collector) and operation control system. Equipment used downstream drying process, its working principle is as follows: wet material after entering drying drum divided into the following workaround: one is the feeding area, the coal into the area exchaged with high temperature and hot air quickly evaporate moisture, the material in large Angle of guide plate copy, to be imported under a workspace;2 The crushing beat cleaning area, equipment design in this area have broken beat cleaning device, wet mud grabbed by grating copy board broken beat, big wet mud after repeated broken beating,which are broken into 20-40 mm particles slime ball, forming curtain material status, increase the heat exchange area, improve the drying rate, reasonably cleaning the mud in the cylinder wall, and prevent mud adhesion;Three is the main drying area, through two area processing wet mud has a granular loose state, the material in this area is inclined by feed plate copying, form a uniform state of material, then have a full heat exchager with the hot air, strong evaporation;Four is pounding broken dry area, in the region after repeated pounding broken mud, mud particles from 20-40 mm broken into 10-20 mm size (request), and moisture further reduced.

| Note: the capacity of equipment is directly related to the reduction of water content of coal. The proportion of precipitation is large, and the production capacity of equipment decreases correspondingly. Specific consulting Dingli company. | |||||
1. Dingli coal slime dryer, with strong overload capacity, large quantity, less fuel consumption, dry low cost;
2. Adopts downstream drying method, the flue gas, and wet material into the drying machine by one side of the dryer, it can take advantage of the high-temperature flue gas to obtain high evaporation strength, the low outlet temperature of the dryer, with high thermal efficiency.
3. It can change operation parameters according to the different material properties, the material in the dryer cylinder body can form stable whole curtain fabric, and the heat exchange more adequately;
4. New type feeding and discharging device, preventing drum dryer feeding jams, discontinuous and uneven return phenomenon, reduce the load of dust removal system;
5. New type of internal structure, to strengthen the effect on scattered material cleaning and heat conduction, eliminates the cylinder to moisture, has a more flexible adaption of sticky and moisture of the materials;
6. New type coal slime drying equipment to achieve the "zero thrust", greatly reducing the wheel wear, the cylinder has a smooth and reliable operation;
7. The drying machine adopts "self-aligning roller device", make the wheel and roll ring with a linear contact, thus greatly reduces the wear and power loss;
8. Adopt unique large coal slime delay drying technology, guarantee the coal slime drying uniformity.
