Flash boiling rotary dryer in red mud industry
2015-07-20 Reads : 72
China, the world's fourth largest producer of alumina, red mud annual emissions of up to several hundred tons. The physical properties of red mud: a particle diameter of 0.088 to 0.25 mm, 2.7 to 2.9 specific gravity and bulk density of 0.8 to 1.0, and a melting point of 1200 ~ 1250 ℃. Production of one ton of alumina to be discharged from 0.6 to 2.0 tons of red mud. Some countries of the red mud into the sea, due to the presence of alkali and other harmful substances and pollution of the sea, endangering fish production. Some piled on land, occupied farmland, river pollution, flapping in the wind drying, and atmospheric pollution. Treatment and disposal of red mud is an international problem! Henan has a famous alumina business after six months of market research visited a number of drying equipment industry, always find a red mud drying can solve the problem, and later in a chemical I encounter the trade fair, after the total exchange and check down, feeling you can try, I get the message through repeated verification tests, and finally developed a special red mud drying equipment, production reached more than 50 tons! become red mud drying a great revolutionary reform of the red mud drying equipment industry principle:! Changzhou Drying Equipment Engineering Co., Ltd. Kay red mud drying equipment is set as one crushed dried quickly and efficiently on the material dried sludge recycling material from the spiral. feeder into the dryer, the strong role of high-speed rotating impeller, the material by the impact, the role of friction and shearing force is dispersed, the bulk materials will soon be smashed full contact with the hot air, heated and dried. Dehydrated dry material with hot air rising, grade large ring particle retention, small particles of red mud discharged outside the dryer dryer selection from the center of the ring, has not recovered from the cyclone and the dust dry or bulk materials by centrifugal force Role Shuaixiang wall, drop to the bottom again be crushed dried. The device solves the final red mud raw water is low, the fine-grained problems, to achieve small equipment, large-scale production, drying intensity, low energy consumption, high thermal efficiency!
