The slime dryer is the rescuer of the abandoned slime. The use of slime can reduce the amount of coal used and save coal resources in this regard. At the same time, the use of slime can be said to turn waste into treasure, which helps coal mines to solve the problem of slime treatment.
Two evaluation indexes for judging the drying effect of slime dryer are the production capacity of slime dryer and the moisture in the finished slime. There are many factors that affect the production effect, including the particle size of the material, moisture, the tilt angle of the drum, the temperature of the drum, and the temperature of the hot flue gas.
According to the drying principle, it can be known that the material is dried by the evaporation of water at a high temperature during the drying of the material. Therefore, when the material to be dried is sent to a slime dryer for drying, the material will also evaporate water, but according to the characteristics of the slime, when the temperature reaches a certain value, the material will harden. During the drying of slime, the internal moisture needs to be transferred to the surface of the bulk material for evaporation. If the material block is too large, the surface hardness is higher or drier, which is not conducive to water evaporation, so the smaller the material block, the better. So that the moisture transfer process can be reduced and the surface of the material is not hardened or retained.
In short, by properly configuring various equipment and adjusting its various conditions to the state, the efficiency of the slime drying equipment will be high and the quality of the product will be excellent.
