working principle:
The rotary kiln dryer is used for pre firing hard ferrite powder and can also be applied in industries such as cement, metallurgy, and chemical engineering. The equipment consists of a main kiln and its supporting transmission device, cooling pipes, fuel system, electrical control, secondary air inlet device, exhaust and dust removal device, and preheating kiln body. It has functions such as over temperature alarm, overload alarm, automatic control of working temperature, and adjustable oxygen in the kiln.
After the wet material is fed into one end of the dryer, it is evenly distributed and dispersed inside the dryer under the flipping of the evenly distributed plate reader in the inner cylinder, and fully contacts with the hot air flowing in parallel (counter current), accelerating the heat and mass transfer driving force of drying. During the drying process, the material can be controlled to move to the star shaped discharge valve in the other section of the dryer under the action of the inclined plate reader and hot air flow, and the finished product is discharged.
Equipment features:
Materials that require low-temperature drying and require continuous drying in large quantities.
The rotary dryer has a high degree of mechanization and a large production capacity.
The fluid has low resistance and low functional consumption when passing through the cylinder.
Has strong adaptability to material characteristics.
Stable operation, low operating costs, and good uniformity of product drying.
Application scope:
Suitable for drying large particles and heavy materials in industries such as chemical, mining, and metallurgy.
For example: ore, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
Drying of powdered and granular materials with special requirements. Such as foaming agent, distiller's residue, light calcium carbonate, activated clay, magnetic powder, graphite, and medicinal residue.
Materials that require low-temperature drying and require continuous drying in large quantities.
