Audited Supplier Coal washing plants are mainly used to remove impurities from raw coal or to classify high-quality coal and low-quality coal. Before clean coal is used, it must first be crushed, graded, washed, dewatered and fines recovered to meet the standards for coking. Coal washing utilizes different physical and physical-chemical properties to remove impurities mixed in raw coal by mechanical means in the coal washing plants and divides it into products with different quality and specifications to meet the needs of different users.
Coal slime is industrial waste generated during coal washing. Due to coal slurry with high moisture content, high viscosity, high water, and low calorific value such many other adverse conditions, it is difficult to realize industrial use, based on the coal slime industry market and the characteristics of coal slurry, through many times technical research and practice, Jiutian company developed a new generation of coal slime drying system meticulously, drying product moisture is less than 15%, the calorific value of coal can achieve 2800-4200 kcal/kg, it is a good fuel of coal boiler. This set of equipment technology is mature, stable running, convenient operation, and maintenance.
The coal drum dryer is mainly composed of a 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.
1, Jiutian 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 of 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 a "self-aligning roller device", making the wheel and roll ring with a linear contact, thus greatly reducing the wear and power loss;
8, Adopt unique large coal slime delay drying technology, guarantee the coal slime drying uniformity.
This type of equipment can be 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, coal, and weakly caking coal, not sticky coal, long flame coal, lignite, coal washing, screening, raw coal, bituminous coal, the tail coal, midding coal, etc. Equipment can be made according to the customers' requirements.
