Coal slime dryer


According to coal slime has high humidity and high adhesive characters, LanJi coal slime dryer mainly composed of the heat source, scattered device, belt type feeder, feeding machine, rotary roller, belt type discharge machine, draught fan, discharging device and distribution box . break up the bond coal slime and dry , increase the coal slime contact area with hot air, which improves the utilization rate.

 

Coal slime dryer Description:

According to coal slime has high humidity and high adhesive characters, LanJi coal slime  dryer mainly composed of the heat source, scattered device, belt type feeder, feeding machine, rotary roller, belt type discharge machine, draught fan, discharging device and distribution box .  break up the bond coal slime  and dry , increase the coal slime contact area with hot air, which improves the utilization rate.

Coal slime dryer working principle:

Due to the stickiness of the coal slurry, it can be divided into several working areas. The first is 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 cannot be formed and was sent to another working area. The second is 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. The third is the 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.

Coal slime dryer Feature:

1. Coal Slime rotary dryer has a strong capacity of anti-overload. It can dry a lot with few fuel consumption and drying cost.
2. It chooses the downstream method for drying, that is, the smoke and wet materials inter into the dryer in the same entrance and get a high evaporation. But the temperature of the exit of the dryer is low. Therefore, it has a high efficiency of heating.
3. It can change the Parameters according to different quality of the materials so as to form a stable full section in the cylinder of the dryer and make a fuller change for materials and heat.

4. It has new equipment for giving and excreting materials. As a result, it avoids the phenomenon of plug, discontinuous and back of materials giving. It also light the burden of the dust eliminating system.
5. The new inner construction strengthen the use of cleaning and heat passing to the separated materials. It also avoids adhesions in the inner wall of the cylinder and has a better adaptability for water and adhesions of the materials.
6. The Coal Slime rotary dryer shows the feature of no help from horizontal push. It decreases the abrasion of roller block and makes the movement of the cylinder stable and reliable.

7. The Coal Slime rotary dryer chooses the Spherical roller block device, which makes the roller and rolling ring connect linearly and lower the abrasion and power consumption,
8. It can control the size and moisture of the production according to the acquirement of the users. The moisture of production being drying can be lower than 8 percent and the size smaller than 8mm.
