Working Principle

Slime dryer  is available for drying all kinds of coal, such as anthracite, lean coal, Mongolian coal, clean coal, nickel coal, coking coal, lignite, raw coal, soft coal, tail coal, middings coal, coal slime, fly ash, etc. The commonly used coal dryers are Mongolian coal dryer, coking coal dryer, raw coal dryer, nickel coal dryer, clean coal dryer, etc. Customers can choose the suitable type according to their actual needs. Coal slime is of certain viscosity. In its drying process, the rotary dryer could be divided into the following working areas:1. Materials lead-in area: in this area, high -temperature hot air contacts wet coal slime, and the moisture in the slime evaporates; under the impact of big-obliquity lifting blades inside the dryer, the coal slime scatters and moves down to next working area;
2. Cleaning-up area: coal slime sticks to the dryer drum when it falls down after being lifted up by the lifting blades; in this area, there is cleaning-up device, which reasonably cleans up the sticky materials from the dryer drum; it also breaks up the lumps or pellets which are already formed by sticky slime; in this way, the cleaning-up device helps enlarge the heat transfer area of the slime and speed up the drying process;
3. Oblique lifting blades area: coal slime in this area is of loose condition with low moisture; and there will be no adhesion phenomena; after being dried by the hot air, the coal slime reaches the ideal condition, and moves to the discharging area;
4. Discharging area: there are no lifting blades in this area; dried coal slime rolls and slides from this area to the discharging mouth to be discharged; the whole drying process thusly comes to an end;
