Rational construction BH three cylinders sand rotary tumble dryer
Description:
The three-cylinder dryer can be used for the drying of dry mixed mortar, yellow sand, cement slag, clay, coal gangue, mixture, fly ash, gypsum, iron powder, etc., widely used in building materials, chemical industry, foundry and other industries. . The investment in the three-cylinder dryer equipment is 1/6 of the imported products. It is made of alloy steel plate and is more wear-resistant than ordinary steel plates.

Working Principle :
The material enters the inner layer of the rotary drum from the feeding device to achieve downstream drying. The material is continuously copied and scattered under the inner layer of the copying plate to realize heat exchange, and the material moves to the other end of the inner layer and enters the middle layer. The countercurrent drying is carried out, and the material is continuously advanced in the middle layer, and the feeding mode is carried out in two steps. The material in the middle layer fully absorbs the heat emitted by the inner layer roller and absorbs the heat of the middle roller, and at the same time prolongs the drying. Time, where the material reaches the -dry state. The material goes to the other end of the middle layer and falls into the outer layer. The material travels in a rectangular multi-loop manner in the outer drum. The material that achieves the drying effect quickly travels out of the drum under the action of hot air. The wet material that does not reach the drying effect cannot be fast due to its own weight. As the material travels, the material is sufficiently dried in the rectangular copy board, thereby completing the drying purpose.
Application:
1. From the form of raw materials, the free-flowing powder, granules, flakes, fibers and other materials can be dried.
2. From the application range of materials, it is widely used in new energy industry, building materials, chemical products, compound fertilizer, organic powder, feed, distiller's grains, starch residue, corn residue, bean dregs, animal waste and so on.
3. From the mechanism of the drum dryer, it can be divided into direct, indirect heating, snorkel heating, steam tube indirect heating, duplex heating and other structural forms.
4. From the drying temperature, it can be automatically adjusted from 60-600. The dryer is mainly used for mineral processing, building materials, metallurgy, chemical industry, compound fertilizer, organic fertilizer, graphite, etc., to dry materials with certain humidity or particle size. The rotary dryer has strong adaptability to materials, can dry various materials, and the equipment operation is simple and reliable, so it is widely used.
Advantages:
The three-cylinder dryer is designed for the characteristics of materials that are not high in initial moisture, moderate in specific gravity, and fluid in the drying process. The utility model has the advantages of compact structure and small floor space, and is the ground of the same output single-tube drying floor area, reliable work, low energy consumption, high thermal efficiency, good material drying effect, easy automatic control and less operators.
