HZG Series Rotary Drum Dryer

Working principle
After the wet material is put into the dryer from one end, the material is evenly distributed and dispersed in the dryer under the stirring of the uniformly distributed lifting plate in the inner cylinder, and fully contacts with the hot air of the co-current (counter-current) to speed up the drying process. Heat, transferred to the driving force. During the drying process, under the action of the inclined lifting plate and the hot air flow, the material can be regulatedly moved to the star discharge valve at the other section of the dryer to discharge the finished product.
Performance characteristics
◎Rotary dryer has a high degree of mechanization and a large production capacity.
◎The resistance of fluid passing through the cylinder is small, and the function consumption is low.
◎Strong adaptability to material characteristics.
◎The operation is stable, the operating cost is low, and the uniformity of product drying is good.
Applicable materials
◎Chemical, mining, metallurgical and other industries with large particles, specific heavy material drying, such as: mines, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
◎Drying powder and granular materials with special requirements, such as: HP foaming agent, distiller's grain residue, light calcium carbonate, activated clay, magnetic powder, graphite, medicine residue.
◎Materials that require low temperature drying and continuous drying in large quantities.
