Product details
Working principle
After the wet material is added to the dryer, it is evenly distributed and dispersed in the dryer under the flipping of the evenly distributed plate reader inside the cylinder, and fully contacts with the hot air flowing in parallel (counter current), which accelerates the heat transfer during drying. Mass transfer. During the drying process, the material can be controlled to move to the star shaped discharge valve in the other section of the dryer to discharge the finished product under the action of the inclined plate and hot air flow.
characteristic
1. The rotary dryer has a high degree of mechanization and a large production capacity.2. The fluid has high resistance and low power when passing through the cylinder.
3. The applicability of material characteristics is relatively strong.
4. Stable operation, low operating costs, and good uniformity of product drying.
Application scope
Suitable for chemical industry. In industries such as mining and metallurgy, large particles with high specific gravity are dried, such as ores, blast furnace slag, coal, metal powders, phosphate fertilizers, and ammonium sulfate. Drying of powdered and granular materials with special requirements. For example: HP foaming agent, distiller's residue, light calcium carbonate, activated clay, magnetic powder, graphite, and drug residue. Materials that require low-temperature drying and require continuous drying in large quantities.
