Best Quality and Large Capacity Coal Slime Rotary Dryer
Application of Coal Slime Rotary Dryer:
Coal slime rotary dryer is developed based on the rotary dryer. It can be widely used in:
1. The coal industry: Coal slime, coal, flotation clean coal, mixed clean coal etc.
2. The construction industry: Blast furnace slag, clay, soil, lime stone, sand, quartz stone etc.
3. Ore processing industry: Various metal concentrates, slag, tailings etc.
4. Chemical industry: Non-drying heat sensitive materials.
Main Features of Coal Slime Rotary Dryer:
1. Coal slime rotary dryer has Strong anti overload ability, large handling capacity, less fuel consumption, low dry cost.
2. Adopt downstream drying method, the hot air with wet materials enter into the dryer by the same side, can use the high temperature air to achieve very high evaporation strength, the exist temperature of dryer is low, the thermal efficiency is high.
3. According to different materials' properties change operation parameters, make the material in the dryer cylinder body can form a stable all broken fabric curtain, qualitative heat is more fully.
4.New feeding and discharging device eliminate the feeding jams, discontinuous, uneven and returning charge etc. Phenomenon, reduce the load of dust removal system.
5. New internal structure, strengthened the already scattered materials' cleaning and heat transfer effect, eliminated the sticky phenomenon in cylinder body's inner wall, make material moisture, sticky adaptability more stronger.
6. Dryer has realized "zero horizontal thrust", greatly reduce the wear of block roller, cylinder's operation is smooth and reliable;
7.Drying machine adopts "center-adjusting roller device", make the cooperation of roller and rolling ring always show linear contact which greatly reduces the wear and power consumption.
8. According to customer's request control product size and moisture, when dry slime, the moisture can reach below 8%, particle size can be controlled below 8mm.
Working Principle of Coal Slime Rotary Dryer:
Coal Slime Rotary Dryer is handling by bringing it into direct contact with a heated gas. The dryer is made up of a large, rotating cylindrical tube, the 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. Working principle: Material to be dried enters the dryer, and as the 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. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.
