Specifications

Three Pass rotary dryer:
1. Can dry sand into -1%
2. Space saving
3. Energy saving 15%
4. Productivity increasing 15%

Product Description

Three pass rotary drier is widely used in drying granule material in fixed moisture range such as yellow ground in dry mortar industry, all kinds of molding sand in casting industry and blast fumes slag in building material/cement industry, small granule resistance and not have strict control to smoke. According to different moisture requirement for dried material in various industries, the finished product water content could be able to below 1-0.5%.

Features
1. Three pass rotary drier use telescope-feed structure, dry the material quickly.
2. Simple design, self-insulation, improve the heat efficiency to exceed 80%.
3. Refined experience, stable operation.
4. Good drying performance. coal consumption<8kg when drying 1 t material.
5. The fuel can be coal, oil, natural gas etc, dry mass and granule and powder material.
6. Reduce land area for 50% compared to single drum rotary dryer,so construction investment is saved 50%,power consumption saved 60%.
7. Finished product moisture can be adjusted depends on requirement of client.
8. Lower outlet temperature .longer dust removal using life.
9. Drive by tug not gear and pinion.
10. Finished product temperature lower than 60oC,packing can be done continuously.

Principle

In the input system there are fan and burner devices. In the discharge system, there are discharge devices and dust collector and other devices, which will be designed according to the customer’ requirement. The material first go into inside drum, because there are the spiral shape boards fixed in the drum, when the dryer makes rotary work, the spiral shape board will stir the material and make the material do longitudinal movement. When the materials reach the right side of the drum, under gravity effect, the materials go into the second drum, because of director plate device, the materials go into the second drum, and the same work principle, the materials go into outside drum, in the drying working process, the materials make three times drying, so the material can be dried completely.
