Product Description

Product Description

From mining to processing, coal can be divided into different types of products such as raw coal, coal slime (slurry), coal slag, lignite, coal peat, anthracite, coke, etc. They are usually have the problem of low calorific value, or unsuitable for transportation and storage. Thus, the drying is needed to upgrade the coal.

Our coal dryer can reduce the moisture of coal from 25-40% to 7% or less, and the calorific value of final coal can be increased by 30-40%. It is mainly suitable for drying materials with high moisture, fine particle size and high viscosity.  
According to different features of coal, the drying temperature, pressure, air volume, and rotating speed are strictly controlled,  and different types of lifting devices, cleaning devices, and crushing devices inside the drum dryer can solve the problem of walls sticking during the drying process. 

 

Process Description

There are many lifting boards in the cylinder body. Through the rotation of the cylinder, lifting boards are driven to throw and spread the material continuously. Moreover, the striking device of the cylinder wall breaks the material again. The lifted material is fully in contact with the hot air coming from the air induction system to exchange heat, evaporate water, and discharged from the outlet.

Our Advantages

1. The hot flue gas and wet material enter the dryer from the same side by the downstream drying method. High evaporation efficiency can be obtained by using hot flue gas;
2. The coal drying system adopts a new feeding and discharging device, which eliminates the phenomenon of blockage, discontinuity, non-uniformity and refeeding of drum drier, and reduces the load of the dust removal system;
3. The new internal structure strengthens the cleaning and heat conduction of the dispersed material, eliminates the phenomenon of sticking wall, and is more adaptable to the moisture and viscosity of the material;

4. The dryer adopts the "adjustable supporting roller device", so that the supporting roller and the rolling ring are always in linear contact, thereby greatly reducing wear and power loss;

5. Product size and moisture can be controlled according to user requirements. After drying, the  product moisture can reach below 8% and particle size can be controlled below 8mm;

6. Multiple fuel choice: coal, diesel, natural gas, waste wood, etc.
