Coal Slime Rotary Dryer

Characteristic  Of Coal Slime Rotary Dryer
Coal Slime Rotary 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:
1, 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;
3,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;



Technical Features Of Slime Coal Rotary Dryer
1.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, 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 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.


WINNERMAC is an outstanding coal slime dryer manufacturer in china. Apart from the reasonable coal slime dryer, it also has many advantages:
1. The coal slime dryer has strong resistance to overload, large processing capacity, less fuel consumption and low drying cost.
2. The adoption of downstream drying method makes the wet material and the heat source enter the machine from the same side, utilizing the high-temperature gas to achieve strong evaporation intensity, lowering the temperature of the discharging area and getting high heat efficiency.
3. The operating parameter can be regulated according to different materials, making more heat transfer more fully.
4. The new type feeding and discharging equipment avoid the phenomenon like block, discontinuous and uneven feeding and material reverting, so the load of the dust removing equipment is effectively decreased.
5. The innovation of the inside structure strengthens the cleaning and heat conduction effect of the scattered material, eliminates the adhesion problem on the inside wall of the machine completely and has a strong adaptability to the materials with high moisture.
6. The coal slime dryer achieves 'zero thrust', greatly reducing the abrasion of the gear wheel and keeping the cylinder function stably and reliably.
