Product Description

Product Description

^{The coal slime is coal washing process of industrial waste residue. 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, Dingli 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 special Coal Slime Dryer uses a special dispersing device to break up the bonded slime and dry it. The contact area between the slime and the hot air is increased, and the heat utilization rate is greatly improved. The dried slime can reduce the moisture to less than 12% at one time, and the dried coal slime can be directly used as a fuel, which makes the coal slime into treasure.}

 

^{Slime Drying Line Compose:}

^{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.}

 

Working Principle

^{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. 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; 4. 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.}

Application

Materials:Widely used for drying coal, lignite, carbon coal, coal, slime, coking coal, gas coal, etc.

Application:Drying coal slime to enable resource recovery and clean utilization.

Product Advantages

1. Reliable operation: The coal dryer achieves "zero horizontal thrust", which greatly reduces the wear of the supporting wheel, and the equipment operates stably and reliably.

2. Make full use of energy: Using the downstream drying method, hot air and materials enter the slime dryer from one side at the same time, which can effectively utilize high-temperature hot air.

3. Energy saving and environmental protection: The coal dryer operates in a fully sealed manner, effectively reducing heat loss and dust emissions. It is also equipped with a multi-stage dust removal system to prevent and prevent again, and provide users with an environmentally friendly site. 4. Intelligent and efficient: Plc intelligent centralized control The system is simple to operate, has high precision, and the tacit cooperation between various equipment greatly improves the efficiency of drying operations.

5. The structure is reasonable and the work is guaranteed: the new internal structure, feeding and discharging devices strengthen the cleaning and heat conduction of dispersed materials, eliminate the adhesion phenomenon on the inner wall of the cylinder, and eliminate the blockage and discontinuity of the feeding. Phenomena such as unevenness and reverse material reduce the load of the dust removal system.
