Henan Sparta Industrial Co.,Ltd

Three-cylinder rotary dryer is mainly applied for stoving slag, sand, coal, fly ash, iron powder, ore, quartz sand and other particle materials.



Sand rotary dryer river sand dryer adopt the saving technology ,fixed structure . Internal cylinder ,middle cylinder and outer cylinder form a since the insulation structure .Special thermal design idew , the elimination of wind tunnel heat loss , increase the heat exchange area and unit volume evaporation intensity , good energy saving effect . The sand dryer is used for drying sand , yellow sand , slag , clay and other raw materials , widely used in building materials , chemical industry , foundry industry , etc , can adapt to a variety of fuels such as coal , oil and gas.

It has the following characteristics:



1. The cylinder protect itself, thermal efficiency can up to 95%.The whole length of the dryer reduced to 50% approximately than mono-cylinder and reduced land investment to 50% approximately?



2. Cylinder adopts heat-resistant and wear-resistant steel plate welding with long service life and easy maintenance..High thermal efficiency , temperature of outer cylinder is 60or belowtemperature of outer mono-cylinder is high to 150°C?



3. Low temperature of outlet, long-service of dust removal machine. It also can be directly connected to air box pulse bag filter?



4. Without gear and pinion drive, but wheel rotation applied, level operation of the complete machine makes system simple and reasonable?



5. Air heater could match boiling furnace, or oil furnace can also be applied, which can dry materials with size below 20mm?



6.Final moisture index can be adjusted according to requirements of customers.

?. Working Principle:

1. Materials will be constantly lifted up by lifting boards, and scattered in spiral type to make hot exchange.

2. And then, material will be moved to middle layer of drum for countercurrent drying, and materials in middle layer of drum will be constantly lifted up by lifting boards. Materials in middle layer of drum can both full absorb heat generated by inner drum layer, and heat generated by middle drum layer, while extend drying time, so materials reached its driest state in this process.

3. Material can move to the outer drum layer from the middle drum layer, material reached the drying effect will be discharged fast along with hot air, while wet materials have not meet the drying effect can' t move quickly due to high weight, so wet material can get adequate drying to reach drying effect thus achieve to complete the drying process.
