The application of silica sand rotary dryer:

Silica Sand rotary dryeris used for drying materials with a certain humidity or granularityin milling of ores, building materials, metallurgy and chemical industry.Sand Rotary has a strong adaptability of materials and it can dry various materials, such aslimestone slag, coal powder, slag, clay stone,sawdust and so on.

The operation is very simple and liable. For this reason, it is used widely.

The strutures of silica sand rotary dryer:

Silica Sand rotary dryer mainly consist of rotary body, raw material feeding plate, driving and supporting device, etc. Its principle of operation: the raw material plate which is arranged reasonably with changeable angles in order, throws moisture materials into the rotary cylinder. Then water will be separated from the materials by hot air-flow and changed into vapour to be discharged into the atmosphere. Then the materials would be dryed. sand drier is used to dry slag, clay, limestone, It is mainly used for cement, chemical, metallurgical, building materials industries.

The operation principle of silica sand rotary dryer:

1.Material to be dried enters the drier, as the dryer rotates,the material is lifted up by a series of internal fins lining the inner wall of the dryer.

2.When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

3.The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.

The main features of silica sand rotary dryer:

1.Simple design, self-insulation, improve the heat efficiency to exceed 80%.

2.Structure delicate, stable operation.

3.Good drying performance, coal consumption <8kg when drying 1 ton material.

4.The fuel can be coal, oil, natural gas etc, dry mass, granule and powder material.

5.Reduce land area for 50% compared to single drum rotary dryer, so construction investment is saved 50%power consumption saved 60%.

6.Finished product moisture can be adjusted depends on requirement of client.

7.Lower outlet tempreture, loonger dust removal using life.

8.Finished product tempreture lower than 60°C, packing can be done continuously.
