rotary dryer introduction
Rotary dryer, also known as rotary drum dryer. Rotary dryer is widely used in building materials, metallurgy, chemicals, industrial drying slag cement limestone, coal, slag, clay and other materials. The aircraft mainly by the Rotary, Jan plate, transmission, seals, and other support equipment and components. With a reasonable structure, well-produced, high yield, and low consumption, the advantages of operating convenience. Rotary dryer’s quality assurance, the highest free installation debugging agent can be checked with other like about rotary dryer than quality or prices.
The coal slurry dryer working principle:
Due to the stickiness of the coal slurry, it can be divided into several working areas. The first is guide area where the wet coal slurry meets the hyperthermia hot air and its moisture evaporates fast. As the material is stirred by the shoveling plate of the big lead angle, the bonding can not be formed and was sent to another working area. The second is cleaning area where the wet coal slurry is raised by the shoveling plate and become the material curtain type. So as the material drops down, it is likely to be bound with the rotary drum wall which can be cleaned by the cleaning device reasonable. In this process, the cleaning device can break the clotting which increases the heat exchange area thus improves the drying speed. The third is the slant flitch area where is wet slurry is in the state of low moisture and loose condition. The material here won’t bond. After the heat exchange the material meet the moisture condition demand, and then goes to the last area-discharging area. There is no shoveling plate here. The material rolls and slides to the dumping mouth and the whole drying process are finished.
coal sludge rotary dryer advantages
1. The internal adopts assembled structure which has improved the accuracy of the equipment and it is easy to transport and install.
2. According to the characteristics of different fertilizers ,we have arranged the second granulation zone reasonably so as to improve the granulation effect.
3. Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption .
4. Temperature induction monitor ,uniform vibration and airproof setting , which improve performance and productivity efficiently .
5. The assorted combustion furnace is a type of energy-efficient and has the characteristics of smaller area ,easy regulation and equipped with greenhouse.
