Direct HZG heating characteristics of rotary drum dryers
To a high degree of mechanization and dryer, large capacity
Small fluid resistance through the shell, low consumption function
The adaptability of the material properties were relatively strong
Stable operation, low operating costs, product uniformity of the dry well
HZG direct heating type rotary drum dryers working principle
◆ wet material from the dryer after the end of input, including simple copy cloth boards are turning device, the material distribution in the dryer and spread evenly with and flow (current) full contact with the hot air to speed up the dry heat transfer , mass transfer driving force. In the drying process, materials with a gradient of copy in the board and the role of thermal air currents, to exercise control to another section of the dryer exhaust valve discharge star product.
HZG direct heating type rotary drum dryer applications
Applicable to chemical, mining, metallurgy and other industries large particles, drying than significant, such as: ore, blast furnace slag, coal, metal powder, phosphate, ammonium sulfate
Special requirements of the powder, the dry granular materials, such as: HP foam, distillers residue, precipitated calcium carbonate, activated clay, magnetic powder, graphite, dregs.
Require low-temperature drying, and the need for large quantities of dry materials.
