Description

Coal slime drying equipment
 
 Introduction and structure;

Zhengzhou Dingli drying equipment co., Ltd is the most professional and authoritative enterprise,which engaged in coal slime drying equipment research and development at home and abroad, is the only science and technology enterprise with an integration of design, production and sales in domestic coal slime drying industry. After recent years of rapid development,it has gradually become the first brand of domestic coal slime drying equipment industry.Because of coal slurry with high moisture content, high viscosity, high water , low calorific value and many other adverse conditions, it is difficult to realize industrial use, according to the present situation around the coal industry market and the characteristics of coal slurry, Dingli called for many experts doing technical research and practice, meticulously developed the fifth generation coal slime drying system, the set of equipment with operation stability, convenient operation and maintenance,reasonable price.
 
 Coal slime dryer system is mainly composed of heat, scatter device, belt feeding machine, feeding machine, rotary drum, belt discharging machine, induced draft fan, the discharger and distribution cabinets.
 
 
Application of the coal slime dryers:
 
The coal slime dryer is applicable for particle materials, and is also applicable for paste and viscous materials which are mingled with particle materials, or materials whose water content is high. 

1) Wood wastes: such as sawdust, wood sawdust, wood chips, wood pieces, wood shavings.
 
2) coal powder, coal slurry, coal dust, coal slime.
 
3) Grain, wheat, rice, corn, bean, sunflower seed, etc.
 
4) Potato starch, tapioca starch, barley malt, etc.
 
5) Sand, clay, slurry, mud,  activated  clay, inorganic mud, argil, etc.
 
6) Vinasse
 
7) Slag, ore.
 
8) Metal powder.
 
9) Fish meal, herb residue, turf.
 
10) Animal wastes. 
 

Working Principle of Coal Slime Dryer

 Coal slime has high humidity and high adhesion. The wet coal is transported by belt conveyor into the coal scattered equipment, after a quick break up, the finished massive coal slime enters into negative-pressure dryer, which has  four work areas as follows:
1.Feed area: in this area, the wet coal rapidly evaporate lots of moisture after being contacted with high temperature and negative pressure air.  On the other hand, the coal slime are lifted by the plate so that it can be leaded into next area before bonding
2.Cleaning area:  the wet materials are lifted by the plate to form a uniform screen in the cylinder. Because the materials are easy to stick on the cylinder wall,  cleaning device is installed. (the cleaning device can quickly clean up the coal slime sticked on the cylinder wall , in the meantime, it can crush  the caking of coal. So that heat exchange area is increased, the efficiency of heat and mass transfer is improved, the drying rate is enhanced)
3.Inclined lifting board area: this area is the cool dry area, the coal slime are loose and has low moisture, and there are no caking phenomenon. The finished products have met the demands of moisture after heat exchange and begin to move into the discharge area
4.Discharge area: there are no lifting boards in this area, the materials slide to the discharge port, so as to achieve the purpose of drying. 
 
 Main features:
 
1.Strong resistance to overload, large capacity, less fuel consumption, and low drying cost.

2.Adopts downstream drying method, flue gas and wet material into the drying machine from the same side;adopt high temperature flue gas to obtain high evaporation strength, the outlet temperature of the dryer is low and high thermal efficiency is good.

3.It can change operation parameters according to the different material properties, make the material in the dryer cylinder body form stable whole broken fabric curtain and improve the heat exchange more sufficiently;

4.With new-type feeding and discharging device, it can prevent from drum dryer feeding jams, discontinuous and uneven return phenomenon, reduces the loading of dust removal system.

5.Special internal structure design, which not only can strengthen the effect on scattered material  cleaning and heat conduction but also eliminate the materials sticky phenomenon, making material  moisture and stickness more flexible;

6. Drying machine achieved the "zero thrust", greatly reducing abrasion between the tug wheel and catch wheel,  make cylinder run smoothly and steadily ;

7.Drying machine adopts "self-aligning roller device", make the wheel and roll ring with a forever linear contact, thus greatly reduces the abrasion and power loss;

8.The product size and moisture could be controlled according to user requirement. The moisture could be lower than 8% while drying the coal slime, the size could be controlled smaller than 8mm.
