| Abstract Scope |
Artificial magnetite pellets have high moisture content and low shatter temperature，So the drying process becomes very complicated. Study of drying characteristic of artificial magnetite pellet was conducted to understand the effect of drying medium temperature and velocity and diameter of green-pellet on moisture ratio and drying rate. The results show that the drying process of artificial magnetite green-ball consists of accelerated drying stage, constant drying stage and decelerated stage. Drying medium temperature and velocity both had a significant reciprocal effect on moisture ratio and drying rate of green-ball during the drying processing, diameter of green-ball scarcely affects it. The Correction Page (Ⅲ) model can explain the drying process accurately, and it is an ideal drying dynamic model for artificial magnetite green pellets. By verifying the model has good practicability. The drying dynamics equation can be written as: MR=aexp(-ktn). |
