Hot Sale And High Efficiency Coal Dryer/ Coal Rotary Dryer/ Coal Slime Rotary Dryer

As we all know, the lower water content of industrial coal slime, the better. Coal slime dryer can process the recycled slime into the particle size less than 13mm, the moisture content less than 13%, making the coal slime can be used as commerical coal. This measure also reaches the goal of high efficiency and large quantities of coal slime recovery, and finally improves the coal preparation processing system. The implementation of the coal slime drying technology has obvious economic benefits and social benefits, reduces the pollution of the environment.

1. Structure of High Efficiency 1.0m*10m Coal Dryer: 

The Coal Dryer consists: 1) Adjustable Motor + 2) Reducer + 3) Transmission Base + 4) Big Gear + 5) Small Gear + 6) Tug Based  + 7) Feed Port + 8) Discharge Port + 9) Air Induced Fan + 10) Drying Cylinder + 11) Roller Ring + 12) Cyclone.

2. Introduction of Coal Dryer/ Coal Rotary Dryer:

Coal Rotary drier is widely used for drying Coal, lignite, Coal Slime etc. This rotary drying machine comes with thermocouples on the feeding and discharging device to control the temperature Rotary drier is mainly composed of cylinder, under frame, feeding and discharging devices, transmission device, gear cover, etc. (Optional auxiliary equipment includes combustion chamber, feeder and discharging device, and dust collection equipment). Rotary drier manufactured by us adopts new lifting plate, which is of functions like guiding, current-sharing, and material rising. The materials are raised and evenly drop so that they are in full contact with heat for better drying efficiency. Our coal rotary drier is designed with the best working conditions, which enables it to save 10-15% of energy and increase 10-15% of productivity compared with common dryers.

3. Features of Coal Dryer/ Coal Rotary Dryer:

• High heat transfer coefficient and high thermal efficiency;
• Large treatment capability, wide application;
• Well drying effect;
• Indirect-heating, no material contamination;
• Retention time can be adjusted, low energy consumption;
• Convenient operation and easy maintenance.

4. Principle of Coal Dryer/ Coal Rotary Dryer:

Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator. The barrel is installed with slope to horizontal line.   First, the coal slime with high humidity enters into the feed zone of dryer machinefrom the feed end to contact with hot air to evaporate water quickly. While other dryer machine don’t have this function, because this process designed to prevent the coal lime paste on the cylinder. Then using the shovelling plate to send the materials to the cylinder to dry the materials. We also installed a cleaning device in the cylinder to avoid the wall sticking, while scattering is to enlarge the contact area of materials and hot air to improve the drying efficiency. After drying, send these materials to the discharging end to complete the whole drying process of coal slime dryer.

How to improve the working performance of coal slime dryer?

(1) We should always check the temperature of all parts of bearing during the operation of coal slime dryer, the temperature shall not exceed 50°C, smooth gear sound transmission, there is no evident effect about the nursing and cylinder rotation, vibration and transmission;

 
(2) The efficiency of the coal slime dryer depends largely on the quality of the combustion chamber, must pay attention to the operation of the coal slime drying equipment, combustor, the blower and dust removal equipment.

 
(3) The procedure of operating coal slime dryer is after launching the dryer, then starting to transport the wet material, and then began to transport the dry material, forming a continuous, uniform operation process.
