Double drum dryer

Double drum dryer

LJSH double drum dryer has made great breakthroughs and innovations on the basis of the traditional single drum rotary dryer structure. From the perspective of drying mechanism, the exchange of materials and hot air flow is more sufficient, more scientific and reasonable, and various thermal indicators have reached the leading level.
LSH type double-cylinder rotary dryer has made great breakthroughs and innovations in the structure of traditional rotary dryers. The exchange of materials and hot air is more sufficient and more reasonable, and various thermal indicators are in the leading position in China.
1. Technical parameters of LJSH double cylinder dryer:

2. Main features of LJSH twin cylinder dryer:
1. The double-cylinder dryer has high thermal efficiency and remarkable energy-saving effect. After testing, the thermal efficiency greatly exceeds the level of about 50% of the traditional single-cylinder dryer. After the equipment is put into operation, the coal saving effect is remarkable.
2. The drying mechanism is scientific and reasonable, and it is effective in energy saving. The material exchanges heat with the hot air flow in the form of radiation, convection and conduction in the inner cylinder, and uses both conduction and convection in the heat exchange in the outer cylinder.
3. The length of the machine is shortened, which is beneficial to the process layout. The length of the whole machine is about 40% shorter than that of the single-cylinder dryer, thereby reducing the construction area of the factory building, saving engineering investment, and more suitable for the process layout of the old factory renovation.
4. The machine adopts the co-current drying process of the material and the hot air flow, and has a wide range of applications. It is suitable for drying various raw materials such as clay, coal, slag, iron powder, etc. It is also suitable for drying various bulk materials in metallurgy, chemical industry and other departments.
5. The machine has a compact structure. The whole machine is arranged horizontally and is supported by supporting rollers. The transmission of large and small gears is cancelled and replaced by the transmission of supporting rollers, which makes the equipment more convenient to install, simpler to operate, more reliable to operate, and higher to operate.
6. A variety of lifting plate designs, the organic combination of the angular lifting plate and the swastika lifting plate, makes the material and hot flue gas exchange more fully, reducing the mechanism of the "wind tunnel" in the dryer cylinder.
7. The external surface area of the machine is reduced by more than 30% compared with the single-cylinder rotary dryer, and the outer cylinder has a thermal insulation effect on the inner cylinder, the surface temperature of the outer cylinder is low, and the heat loss is small. the working environment and working conditions.
8. Adopt frequency conversion speed regulation to adjust the speed of the cylinder, according to the water entering the machine and the output requirements, adopt the appropriate speed to ensure the needs of the next process.
9. Automatic temperature monitoring system makes the operation more convenient.
