Coal drying machine for coal gangue and lignite coal drying price in China





Coal drying machine is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material, it is handled by bringing it into direct contact with a heated gas.


Coal drying machine structure:

Coal drying machine is formed by rotary body, lifting blade, driving device, supporting device and bigger gear, smaller gear, motor and reducer.

Coal drying machine working principle:

Due to the stickiness of the coal slurry, it can be divided into several working areas.

First, guide area where the wet coal slurry meets the hyperthermia hot air and its moisture evaporates fast. As the material is stirred by the shoveling plate of the big lead angle, the bonding can not be formed and was sent to another working area.


Second, cleaning area where the wet coal slurry is raised by the shoveling plate and become the material curtain type. So as the material drops down, it is likely to be bound with the rotary drum wall which can be cleaned by the cleaning device reasonable. In this process, the cleaning device can break the clotting which increases the heat exchange area thus improves the drying speed.


Third, slant flitch area where is wet slurry is in the state of low moisture and loose condition. The material here won't bond. After the heat exchange the material meet the moisture condition demand, and then goes to the last area-discharging area. There is no shoveling plate here. The material rolls and slides to the dumping mouth and the whole drying process are finished.
