HZG Rotary drum drier principle is the subject of a slightly inclined cylindrical body and can adjustable speed within a certain range, the wet material from the feeder into the inner cylinder, the inner cylinder cloth copy board is turning, the material was dried evenly distributed inside with the dispersion and full contact with the hot air through the barrel (or counter-current) to speed up the drying heat and mass transfer. So as to achieve the purpose of drying. The device can be used in various forms of copy board to adapt to different materials, simple structure, reliable operation, easy maintenance, large production capacity.
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, phosphate, ammonium sulfate. There are special requirements powder 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 large quantities of continuous drying of materials.
