Brief introduction of coal slime dryer:
1. Slime itself has high humidity, high adhesion. In view of this feature, coal slime dryer adopts a unique device to break up the bonded coal slime for drying, which enlarges the contact area of slime with hot air and makes heat utilization get greatly improved.
2. The coal slime after drying can reduce the moisture to be 12% by one-time .After drying ,the coal slime can be directly used as fuel, turning the coal slime into treasure.
Structural components of coal slime dryer:
The coal slime dryer mainly consists of heat source system (hot blast stove, gas furnace, fluidized bed), feed system, transmission system, drying system, dust removal system, ventilation equipment, electrical control system.
1. It has strong overload capacity, large processing capacity, less fuel consumption, low drying costs.
2. Coal slime dryer adopts downstream drying method. The flue gas and wet material get into the drying machine by the same side , which can take advantage of the high temperature flue gas to obtain high evaporation strength,moreover, the outlet temperature of the drying machine is low and the thermal efficiency is high .
3. The coal slime dryer can change operation parameters according to the different material properties.The material in the dryer cylinder body can form stable whole material curtain and the heat exchange will be more adequate.
4. New type of feeding and discharging device put an end to the problems of feeding jams, discontinuous feeding and uneven feeding, reducing the load of dust removal system
5. New type of internal structure strengthens the cleaning and heat conduction effect on scattered material, which makes the coal slime dryer have stronger adaptability to the material water content and stickiness.
6. The coal slime dryer achieves the "zero thrust", greatly reducing the wheel wear, realizing the smooth and reliable operation.
7. Coal slime dryer adopts "self-aligning roller device", making the linear contact between wheel and roll ring, thus it greatly reduces the wear and power consumption.
8. It can control product granularity and moisture according to users’requirements , when drying coal slime, product moisture can reach below 8%, the particle size can be controlled under 8 mm.
