Environment Friendly Three Cylinder Industrial Drying Equipment For Slag

Environment Friendly Three Cylinder Industrial Drying Equipment For Slag

Equipment Introduction:

The environmental friendly three cylinder industrial drying equipment improves the internal structure on

the basis of single drum dryer, the pre drying of wet material is added before getting into the dryer and

prolong the drying time of wet material in the dryer. It is widely used in various industries’ slag, clay,

coal, iron ore powder, ore powder, and dry mixed mortar, yellow sand and other mixed materials.

Performance Characteristics:

1. Low outlet air temperature, longer service life of dust removal equipment.

2. Sizes of lump materials, particles, and powders are less than 20mm can be dried.

3. Gear driving is not required and it’s directly driven by roller, with higher mechanical efficiency.

4. Without the phenomenon of air leakage, the sealing difficulty is totally solved, and the installation can

be finished within a few hours.

5..It makes use of waste to produce useful product, like fertilizer, concrete aggregate etc. Therefore, it is

environmental friendly.

6. The self-insulation thermal efficiency of three cylinder dryer can reach above 70% (the self-insulation

thermal efficiency of traditional single drum dryer is only 35%), it has remarkable energy saving effect.

7. Final moisture indicators can be regulated easily according to the request.

8. The temperature of discharged material is < 50 ℃, which can be directly conveyed into the storage

silo, needless to cool down in the cooling shed.

Working Principle:

Materials get into the internal rotary drum from the feeding device, to realize the downstream drying,

materials are lifted up and down constantly by the inner layer lifting plates and the heat exchange is

realized under the form of spiral moving, materials move to the other side of the inner cylinder and then

get into the middle cylinder, and materials are lifted up and moved forward in the middle cylinder, by the

way of two steps forward and one step back, materials absorb the heat both coming from the inner

cylinder and the middle cylinder, meanwhile, the drying time is prolonged, and materials reach optimum

drying status at this stage. Material move the other end of the middle cylinder and then get into the

outer cylinder, the dried materials are quickly discharged from the cylinder under the function of hot

wind.?
