product details

Working principle
After being fed into one end of the dryer, the wet material is evenly distributed and dispersed in the dryer by flipping the plate reader evenly distributed in the inner cylinder, and fully contacts with the hot air flowing in parallel (counter current), accelerating the heat transfer during drying and transmitting it to the driving force. During the drying process, the material can be controlled to move to the star shaped discharge valve in another section of the dryer to discharge the finished product under the action of the inclined plate and hot air flow.
HZG系列回转滚筒干燥机Adapt to materials
The chemical, mining, metallurgical and other industries dry large particles and materials with high specific gravity, such as mining, blast furnace slag, coal, metal powder, phosphate fertilizer, and ammonium sulfate.
Drying of powders and granular materials with special requirements, such as 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.
Performance characteristics
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.
