Introduction of mining dryer 

It is mainly used for drying wet materials in building construction, metallurgy, chemical industries, and it can dry various materials with strong adaptability. Besides, it is common drying device in cement plant with simple and reliable operation.



In our company, this series applies the new type scatter plate device; it can guide direction, flow on an average and scatter the material and so on. And it can make the material in the thin, average and complete condition. Contact the heat airflow completely and use the heat energy fully. Moreover, it adopts reasonable operational parameter, and compared with general drier, it reduce the coal and power consumption above10-15%,and increase the output above10-15%. At present, it is widely used in cement and mining industries.



 Dryer application:



1) Ore: ore,slag,mineral power,limestone, quartz, fluorite powder,iron ore,metal ore concentrates, metal tailings,etc. 

2) Metal: metal powder, iron powder, iron filings, steel scrap, copper filings, etc. 

3) Chemical industry: gypsum powder of desulphurization gypsum stir-frying half water model and building gypsum powder,clay,diatomaceous earth, kaolin,bauxite

4) Coal: raw coal,coal slime, coal,coal ash,coal cinder 

5) Sand: sand,quartz sand,moulding sand,river sand 

6) Various crystals: light calcium carbonate, activated clay, magnetic powder, graphite, mineral mud, clay, lime slurry, ore slurry, phosphorus slag, aluminum red mud, feldspar powder, fly ash, blue carbon, potassium, sodium, calcium, barium and alkali metal or silicate minerals in the alkali metal.

7) Wood: sawdust, small wood chips, wood veneer.

(8)Fertilizer: compound fertilizer, organic fertilizers, inorganic fertilizers, ammonium sulfate fertilizer 

9) Agriculture: straw, grass, turf.

10) Animal manure: chicken manure, duck manure, cow dung, etc.



Applications of rotary dryer:



1. The rotary dryer is widely used for drying the chalk slags, coal powder, slags, clay and other materials in the building materials, metallurgy, chemical industry, cement industry.

2.In our company, this series applies the new type scatter plate device;

3.  It can guide direction, flow on average and scatter the material and so on.

4.And it can make the material in the thin, average and complete condition.

5.Contact the heat airflow completely and use the heat energy fully.

6. Moreover, it adopts reasonable operational parameter, and compared with general drier.

7.It reduce the coal and power consumption above 10-15%, and increase the output above10-15%.

8. At present, it is widely used in cement and mining industries.



Technical advantage of rotary dryer:



1.Our dryer adopts new spreading plate device, which has guidance, flow, material functions

2.It can make the material content in the dryer radial cross section to full uniform, material will become thin and all.

3.The state of the heat flow entirely, to achieve the purpose of make full use of the heat.

4. Our dryer choose reasonable operating parameters, coal consumption and power consumption of general baked dry machine more than 10-15%, one machine yields above 10-15%.

5. It has been widely used in the cement and mineral processing enterprise.













Working principle of rotary dryer:



1.Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator.

2.Materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together.

3.Materials go to the lower side by gravity when the barrel is rotating.

4.Lifters on the inner side of barrel lift materials up and down in order to make materials and  hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.



Features and Benefits of dryer:



High heat exchange rate, low energy consumption

Strong adaptability, large capacity

High aerated rate, low pressure drop, high operating spring and big interface

Reliable performance, easy operation, Wide range of application



Working principle of dryer



Drier mainly consists of revolution body, raise material board, transmission device, supportive device and sealing ring, etc.

The heat sources of the drier is from the combustion train, and is adopts down-flow heating methods. When the materials enter into the body from the feeding device, it will be pushed back by the spire raising board. As the drier is in an inclined position, the materials will be down to the lower end under the influence of gravity and rotation, but the raising board will be threw to the upper end for scattering. This procession makes the material well-distributed in the body, and then ensure the heat exchange with the heat wind. After repeated cycle with this procession, the moisture content will be dried.
