In many industrial productions, a large amount of sludge is produced. If the sludge is not properly treated, it will cause great damage to the environment. Usually, we can use sludge drying equipment to solve this problem, which can significantly increase productivity, and excellent sludge drying technology is particularly important.

　　  The flash dryer is stirred by a high-speed crusher, and part of the dry sludge and mixed sludge are exposed to high temperature air at a speed of 20~30m/s. The sludge moisture will quickly evaporate within a few seconds, and the moisture content can be reduced to 8% to 10 %. Flash drying technology is a solid fluidized dilute phase pneumatic conveying technology. In the application of sludge drying, the sludge is in direct contact with the heat medium and suspended in the high heat flow, which significantly increases the contact area, enhances heat transfer, and shortens the drying time .
