Drying Process of Slime

    As an energy resource, coal is indispensable in industrial development and daily life. In the mining process, after washing, open-pit stacking, part of the coal was washed away by water, and coal sludge was formed through precipitation, which caused the loss of coal source. Similarly, because these slimes have many unfavorable conditions such as high moisture, high viscosity, high water holding capacity and low calorific value, it is more difficult to recycle. The slime drying process is an effective method for slime recovery and utilization.

    The slime first passes through the forklift shovel feeder, and then is evenly fed to the belt conveyor by the feeder, and then enters the dryer through the guide pipe. The heat generated by the combustion of the fuel in the hot blast stove is in the exhaust fan It enters into the main machine to make contact with the materials under the action of, the coal slime is evenly dispersed and fully contacted with the hot air under the turning of the copy board evenly distributed in the drying drum, which accelerates the drying heat transfer and mass transfer of the slime and evaporates the water. The dried slime is transported to the finished product pile by belt conveyor.

Advantage

• 

  The slime drying production line has strong anti-overload capability, large processing capacity, low fuel consumption and low drying cost.

• 

  The slime dryer production line system adopts a new type of feeding and discharging device, which eliminates the phenomenon of blocking, discontinuity, unevenness and material return of the drum dryer, reducing the load of the dust removal system.

• 

  The new internal structure strengthens the cleaning and heat conduction of the dispersed materials, eliminates the sticking phenomenon of the inner wall of the cylinder, and has a stronger adaptability to the moisture and viscosity of the materials.

• 

  The slime drying production line system realizes "zero level thrust", which greatly reduces the wear of the back-up wheel, and the barrel operates smoothly and reliably.

• 

  The drying line is widely used. It is suitable for the drying of blast furnace slag, clay, limestone, sand, quartz stone and other materials in the construction industry; and the drying of various metal concentrates, waste slag, tailings and other materials in the mineral processing industry.
