Overview：The HZG rotary drum dryer is a cylinder with a slightly inclined main body and adjustable speed within a certain range. The wet material is fed into the cylinder by the feeder,
Consultingworking principle
After the wet material is input from one end of the dryer, the material is evenly distributed and dispersed in the dryer under the turning of the evenly distributed plate copying device in the inner cylinder, and fully contacted with the co-current (counter-current) hot air, which speeds up the drying and heat transfer. Pass to the driving force. During the drying process, the material can be moved to another section of the dryer to discharge the finished product under the action of the inclined plate and the hot air flow.
Adapt to materials
◎In the chemical, mining, metallurgical and other industries, large particles and heavy-weight materials are dried, such as mines, blast furnace slag, coal, metal powder, phosphate fertilizer, and ammonium sulfate.
◎Dry powder and granular materials with special requirements, such as HP foaming agent, distiller's grains, light calcium carbonate, activated clay, magnetic powder, graphite, and medicine residue.
◎Materials requiring low-temperature drying and continuous drying in large quantities.
Performance characteristics
◎The drum dryer has a high degree of mechanization and a large production capacity.
◎The resistance of the fluid through the cylinder is small, and the function consumption is low.
◎Strong adaptability to material characteristics.
◎The operation is stable, the operation cost is low, and the product drying uniformity is good.
