The Four Working Sections of Coal Slime Dryer

In the drying process of coal slime dryer, the wet coal slime will enter into the scattered device through the belt conveyor of coal slime drying machine. When the slime bricks entering into the coal slime dryer, it has the following working sections:

One is the material area pilot of coal slime drying machine, where the wet coal from this area will be mixed with the high negative pressure hot air, after fusion is a lot of moisture will be evaporated rapidly, and the slime in the copy board copy with the big lead angle will not be bonded, which will be copied into the next working area;

The second is the cleaning area, wet coal in this area is in the material screen state raised by the copy board, which is easy to form the bonding cylinder wall phenomenon when the material falls in this region. Due to the design of coal slime cleaning device, the cleaning device can quickly clear out the bonding cylinder wall, in this process, the cleaning device also has crushing role for the material pellet caking, thus increasing the thermal conversion area, so as to improve the efficiency of heat and mass transfer and the drying rate;

The third is the inclined lifting plate area of coal slime dryer, this area is the low temperature drying zone, this zone has a low moisture content of coal slime in loose state. This district does not have adhesion phenomena after heat exchange, and the products reach the required moisture requirements, and finally move into the feeding zone;

The fourth section is the discharge zone of slime dryer. In this zone, it is not provided with the roller drying host copy board, and the material in this area is rolling and sliding to the discharge mouth to complete the whole drying process of coal slime drying machine.
