文摘

In order to research the drying efficiency of a rotary dryer, a three-dimensional simulation model of roller is built. The temperature distribution in the dryer is simulation modeled using Fluent code, and the simulation result is contrastively analyzed by a thermal imaging test. Using the material curtain distribution location and uniformity as evaluation parameters, EDEM studies the impact of the dryer’s internal structural parameters and the production parameters on the material curtain distribution characteristics. A contrast experiment is conducted to obtain the optimized structural parameters and production parameters of a rotary dryer.
