Equipment Overview: Wet material from the dryer into one end of the inner cylinder under cloth copy board is turning, the material evenly distributed and dispersed in the dryer, and full contact with and flow (countercurrent) hot air to speed up the drying heat and mass transfer driving force. During the drying process, the material under the action of the copy board and the hot air with the inclination, adjustable moved to another section of the dryer exhaust discharge valve star products. Applications: used in chemical, mining, metallurgy and other industries large particles, drier than the major materials. Such as: ore, blast furnace slag, coal, metal powder, fertilizer, ammonium sulfate. There are special requirements of powdery, dry granular materials. Such as: HP vesicant, lees residue, precipitated calcium carbonate, activated clay, magnetic powder, graphite, dregs. It requires low-temperature drying, and need continuous drying of bulk material. Features 1. High degree of mechanization dryer drum, large production capacity; 2. fluid through the barrel resistance, functionality and low consumption; 3. the material properties of strong adaptability; 4. stable operation and low operating costs, uniformity of product drying is good.
