Coal Dryer

What is Coal Dryer?

Coal dryer is a new type drying equipment grown from rotary dryer to dry all kinds of coal. Coal itself is usually of high humidity and high agglutination. The coal dryer developed by FTM is targeted at these characters and suitable for various particles in coal industry like coal slime, fine coal, tail coal, etc. The special device smashes wet coal, which improves the heat transformation efficiently. Dried coal can be used as the source of the power plant as well as raw material in industry. In addition, coal drying machine is also applied for drying other material of certain humidity and particle size in building materials, metallurgy, mining and so on.

Applications of Coal Dryer Machine

Coal dryer is available for drying all kinds of coal, such as anthracite, lean coal, Mongolian coal, clean coal, nickel coal, coking coal, lignite, raw coal, soft coal, tail coal, mid coal, coal slime, fly ash, etc. The commonly used coal dryers are Mongolian coal dryer, coking coal dryer, raw coal dryer, nickel coal dryer, clean coal dryer, etc. Our coal dryer machine is designed based on customer need. 

Examples of Coal Dryer Application

Working Principle of Coal Dryer Machine

Wet coal of a certain humidity firstly passes through a professionally designed dispersion device. The well-dispersed coal is conveyed to the feeder, by which it is then fed into the cylinder. Here in the rolling drum, wet coal is thrown up and down by blades and gets water and heat exchanged. The dried coal is belched out of the drum by the star-shaped unloader and conveyed to the package. The entire drying process is completed.

Structure of Coal Dryer

Structural Advantages of Coal Drying Machine

• The minimization of the drying cost. The two ends of the cylinder are sealed well and heat is preserved to decrease the heat loss. It adopts the low-cost coal as the heat source fuel to reduce the fuel expenditure. In addition, coal drying machine is in fully automatic to reduce manpower cost.
• Maximum safe production. Full automation during the whole production process prevents the occurrence of accidents.
• High-quality finished product. Coal dryer adopts three-layer settlement structure to reduce the dust pollution of the material. High-temperature rapid process reduces the organic elements loss of the material. Online moisture inspection and fuzzy control, the water content of material is consistent after the drying process.
• High drying strength. The water removal amount per hour can reach up to a maximation of 8000KG with continuous production.
• High drying efficiency. Coal dryer adopts high-temperature rapid drying process; the hot air temperature utilization has been increased by 40 percentage points compared with the normal low temperature drying method. With the heating system with as high as 90% thermal efficiency, the overall thermal efficiency of the dryer amounts to 73%. Part of the heated air will be put into the head end for continuous heating, which reduces heat loss.

Environmental Value of Coal Dryer

>> Provide solutions to the pollution and occupied area problems of coal slime in coal separating plants. 

>> Reduce the power generation cost of coal and power plants.

>> Promote the comprehensive utilization of coal.
