Three return dryer that is efficient modular three drum dryer. Large three-cylinder dryer, there are usually six to seven meters long, is not the cone, the flow of material with a rotating cylinder by cylinder blades struck forward, but with a straight. Three return dryer is made up of three concentric nested cylinders of different diameters together, rather than a chain, it is a chain, this particular form of structure determines the size of its production, so this new bake Dryer also called three return dryer. LJSH efficient three-cylinder dryer combined with a compact, small footprint, is one area of ??the same production single cylinder drying ground dichotomy, reliable, low power consumption, high thermal efficiency, good material drying effect easy to achieve automatic control, less operator. The main purpose of the three return dryer efficiency modular three drum dryer is mainly used for a variety of sand particles in the drying certain humidity range of materials, such as dry mortar industry with sand, foundry industry with. Blast furnace slag cement building materials industry with. Small size clay, for the chemical industry can not afford to chemical changes, small particles of the material is not afraid of high temperature and dust soiled. Depending on the industry after the final moisture drying material requirements, material moisture content after drying can reach 1-0.5 percent. Three return into the material inside the dryer to stick the tube wall and the lifting plate is appropriate. Into the gas temperature dryer heat exchange should not be higher than 750 degrees Celsius, if available at the entrance to the inner tube and the special requirements of high temperature resistant steel plate drying, dryer Yang plate material. Features three return dryer 1, 20% of foreign investment in equipment is imported products, wear-resistant manganese plate manufacturing, wear-resistant than ordinary steel 3-4 times. 2, the material initial moisture 15%, final moisture to ensure 0.5-1% or less, is a cement plant slag powder, dry mortar production line and other projects drying the product of choice. 3, than the traditional single cylinder dryer to improve the thermal efficiency of over 40%. 4, fuel applicable anthracite, bituminous coal, coal, oil, gas. Materials can bake 20-40mm following blocks, pellets and powder materials. 5, than monocular dryer to reduce the footprint of about 60%. About 60% lower construction investment, easy installation. 6, seamless wind phenomenon, completely solve the sealing difficulty. 7, the material temperature ≤60 degrees, can be directly feed repository, without injecting cooling shed cooling. 8, the outer cylinder temperature ≤60 °, the exhaust gas temperature <120 degrees, dust removal equipment bag used more than twice as long time. Coal is the single cylinder dryer 1/3, saving 40%, tons of standard coal consumption <9 kg. Troubleshooting of 1, the moisture content of the material after drying three return dryer is greater than the prescribed value, the elimination method is to control the production capacity of the dryer, and increase or decrease the supply of heat; 2, rolling circle of the cylinder operation swing, the reason is female connector side rolling circle without clamping plate to make the elimination method is to use rolling circle and female connectors maintain proper uniform and clamping to prevent tight and prone to accidents; 3, large gear pinion meshing gap is destroyed, the reason is a tugboat wear;.. b gear wheel wear;. c pinion wear. Its elimination method for turning or replacement, you can also install or paired opposite updated according to wear; 4, whole body vibration, the reason is a tug device and dock connector is damaged. Remedy is correct tightening joints, it is in the correct position; 5, rolling ring flank wear, eliminating method is based on the degree of wear Toru, turning on the rolling ring or replacement.
