Coal Dryer Introduction
From mining to processing, there are many types of coal.  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 system mainly consists of heating part (that can be designed accroding to the heating source you chose), feeding machine, rotary dryer, discharging machine and dust removal equipment, etc. This coal dryer system can be used for drying all types of coal, lignite, raw coal, carbon coal, anthracite, bituminous coal, lean coal and poor lean coal, etc, and the drying temperature, pressure, air volume, and rotating speed are strictly controlled according to different features of coal. 
Besides, 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. 

Coal Dryer Drying 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 crushing 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.

Coal Dryer Advantages
1. High evaporation efficiency 
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. High efficiency 
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. Wide adaptation to the moisture and viscosity of the material
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. Longlife service
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;

1.Fully technology support, free factory design and reasonable drying plant layout.

2.100% carry out as contract.

3.We can send engineer to oversea to install at site.
