¡¡¡¡ Wet material by the belt conveyor or bucket elevator to the hopper, add the feed. Dryer to the main body and are slightly inclined rotary cylinder body. Materials into the internal cylinder, the hot air through the tube into contact with, or upstream or downstream and heating for effective contact with the wall was dry, the dried product from the other side of the lower part of the material. In the drying process, and materials through the use of the slow rotating cylinder, in gravity from one end to the lower high end mobile. Tube wall with the body copy board forward, it continually shed and put three inside the room used materials so that the thermal contact surface materials greatly enhance and improve the drying rate and to move materials. Hot carriers (hot air, flue gas) dry materials through its narrow cyclone to collect dust after the evacuation zone.
Characteristics:
Production capacity, and can be continuous operation; structure is simple, fault less, easy to operate, low maintenance costs, operational stability; the application of a wide range of available dry powder, granular, rules, block materials, operating flexibility, and permit the production of Products there is greater volatility in output, without affecting the quality of the product. Easy cleaning. Large equipment, installation, demolition difficult heat capacity coefficient small, the thermal efficiency is relatively low (but steam-tube dryer to a higher thermal efficiency).
The scope of application:
Applicable to chemical, mining, metallurgy and other industries large particles, the major materials than dry, such as: ore, blast furnace slag, coal, metal powder, phosphate, ammonium sulfate. Have special requirements for the powder, the dry granular materials, such as: HP foam, distillers residue, precipitated calcium carbonate, activated clay, magnetic powder, graphite, dregs.
