Of course, air-dryer, here refers to the changes in coal quality coal quality is homogenized stable, rather than instantly changing from coal, otherwise, none of the drum dryer burner can be adapted or adjusted. Finally, to meet environmental requirements, today's society with the increasing people's living standards, environmental protection requirements are also increasing, so it is proposed to use the dryer Coal industry higher environmental requirements. Drum dryer burner is one must decide whether to form a good flame equipment, so the purchase of coal preparation plant with dry confidential selected burner. The second is to have a different capacity from coal combustion, coal quality changes when the drum dryer manufacturers, by adjusting the outlet velocity, changing the intensity of air mixed with the coal, the flame still meet the needs of calcination. For a long time, rotary drum dryer has been using the L-shaped lifting plate structure, the use of such lifting plate of rotary drum dryer low yield, high heat consumption, low thermal efficiency, high and difficult to discharge water control, has been in a state of inefficient work. Mining equipment in the most widely used devices are drying drum dryer for drying a variety of materials. It has high productivity, easy operation and features. The heat transfer medium and the way it dry wet material can be divided into direct heat transfer between the rotary drum dryer and indirect heat transfer drum dryer two. Barrel drum dryer memory in some wind tunnel pulse from front to back airflow dryer, these wind tunnel extending from the feed end to the tail, part of the hot air heat exchange late, directly through the wind tunnel to drain away. Low traditional L-shaped lifting plate productivity following main reasons: first, the presence of a wind tunnel. Second, heat and mass transfer in a short time. After the drum dryer cylinder of the L-shaped lifting plate the material mentioned in the air, the material will be immediately thrown down, stay in the air time is very short, resulting in a material with a hot air contact time is short.
