Dryer

Rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.
Rotary dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The rotary dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through rotary dryer under gravity. Material to be dried enters the dryer, and as rotary dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.
This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine etc.
Rotary dryer can be widely used to dry sludge, sand, coal, gypsum, sawdust, mineral slag, sludge, chicken manure, and it is simple to operate.

Coal dryer is now hot equipment in the world. Coal is vital energy resource in various industries and daily life. When coal is washed or stored in open yard, some is washed away which forms coal slime later. This is a great loss. Coal slime is of high moisture and low heat, which means poor economic value. However, coal dryer solves this problem perfectly.
Under normal conditions, moisture inside of coal slime is 20-30%. After drying, the moisture can be reduced to 0.1%. Thus, coal slime can be used in many occasions. Coal dryer turns waste into treasure.
How does coal dryer work?
Coal dryer is divided into several sections for higher efficiency.
A. Transmission section. Wet material enters coal dryer, then it gets full contact with hot air, moisture inside gets vaporized. With lifting boards elevating and scattering materials repeatedly, wet material is conveyed to next section.
B. Cleaning section. When materials fall down, they are easy to stick on the inner wall of the cylinder. During this process, cleaning device breaks the clumps. This spreads the surface area of heat exchange and improves heat efficiency.
C. Lifting boards section. Wet material gets loose and of low moisture content that meets the requirement.
D. Discharging section. No lifting boards in this area. Materials roll to the outlet coal dryer. The whole drying process is completed.

Sand dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.
Sand dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. Sand dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters sand dryer, and as sand dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of sand dryer. When material gets high enough to roll back off the fins, it falls back down to the bottom of sand dryer, passing through the hot gas stream as it falls.
This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case sand dryer is called a direct heated dryer.

Vacuum dryer

Polyester spiral dryer fabrics is suitable for the dryer section of the paper machine ,printing and dyeing machine and horizonal belt washer ,also for the coal washing.It has many advantages,such as----used conveniently,repaired easily, having long lifetime,cheaper than Polyester weaving dryer fabric.

1.Running under the airtight state.
2.Enhance the reclamation rate of solvent.
The vertical vacuum mixing dryer can replace the traditional single-spiral mixer, vibrating dryer and water heater, whose several processes can now be performed by the single dryer. Running under the airtight state, the dryer can improve the production environment and enhance the reclamation rate of solvent. Due to its compact structure comprising of the specially shaped mixing shafts installed in an intersecting manner and rotation vis-a-vis, the materials and additives can be evenly mixed. The scraper is used to remove the material to avoid the sticking of the inner walls.
