The main disadvantages are air drying air drying in our country is an application of the most widely distributed oldest dryer, air dryer with different successful development of new, air-drying my dry areas in the ascendant. Because of the drying time is short for easy drying materials by high temperature metamorphism; not suitable for viscous materials dry pipe than the plant generally more than 20 meters, limiting the installation of restricted its development. The main disadvantage is that the dry air dryer duct is too high, in order to reduce its height, in recent years there have been several new air dryer: ① multistage air dryer. Several shorter drying tube in series drying machine, drying tube is set separately for each of the cyclone and fan dryer types, thereby increasing the total length of the inlet section. ② impulse dryer. Alternately with a diameter narrowing and broadening drying tube (pulse tube), the tube gas velocity due to alternate, thereby increasing the relative velocity of the particle stream. ③ Tornado air dryer. So that the material particles carried Shandong air dryer, the drying chamber into the cyclone tangentially, in order to increase the relative speed between gas and particles, also reduces the height of the airflow dryer. Note the use of air dryer 1. Must be lubricated for each piece before it is put to use lubrication. 2. When put into the dryer must be properly adjusted, the supply of adequate quality (gauge 6atm above) steam dryer to make full capacity. 3. Note the use of start-stop sequence. Before commissioning the first to open the steam valve, regulating valve closed, and then start the fan, the temperature rises gradually as pipeline stroke play regulating valves, position it is in production. When the temperature reaches pipeline stroke requirements, starter feeders feeding. Look how wet material and finished feed water to adjust the level of the water much. Shutdown in reverse order, first stop feeder drain the material to be seen after the fan stops, turn off the steam valve. 4. Good scraper centrifuge adjustment operation, the wet material moisture low and stable, feeders feeding evenly. 5. Pay attention to fire safety, the dust around the dryer promptly cleaned. Smoking is strictly prohibited in the workshop. Welding repairs must be shut down and do a good job handling the fire. Domestic dryer, after-sale protection (certified), the dryer is provided by Changzhou Drying Equipment Co., Kinder. Kinder Changzhou Drying Equipment Co. (www.jian-da.com) is an industry leader in Changzhou, Jiangsu, drying equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Kinder dry leadership with the staff warmly welcome all inquiries negotiations to create Kinder dry a better future.
