Rotary Dryer application:
Rotary drum Dryer Machine is widely used in building materials, metallurgy, chemical industry and cement industry, which is widely used to dry the stuff such as limestone, coal powder, slag and clay. The main features of the Mongolian coal dryer
1.dryer anti-overload, large capacity, low fuel consumption, low-cost drying;
2.the downstream drying, flue gas and the wet material into the dryer on the same side, can take advantage of the high temperature flue gas to get high evaporation, dryer outlet temperature, high thermal efficiency;
3.according to different material properties to change the operating parameters, so that the material to form a stable full cut fabric curtain in the dryer cylinder body, the quality of heat exchange more fully;
4.the new feeding, nesting devices, put an end to the drum dryer feed plug, discontinuous, uneven, and returning materials such phenomena, reducing the dust load;
coal 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, bentonite 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
Coal slime rotary dryer is a kind of stable and reliable heating drying equipment, designed to dry materials of high moisture and strong stickiness, such as coal slurry, mud, gypsum, humid swell soil, electroplate mud and so on. The performance of coal slime dryer is better than tube rotary dryer and blade rotary dryer.
rotary dryer special features:
- · Drying material with co-current or counter-current hot gas, the heating efficiency can be up to 95%.
- · Coal Slime dryer should be operated under high temperature and low oxygen to avoid materials being burnt when drying.
- · Large drying capacity, highly industrialization and low cost.
rotary dryer main applicable areas:
- 1. Coal industry: drying coal, coal slime, coal with flotation, drying mixed coal;
- 2, Construction industry: drying cinder, blast furnace slag, clay, limestone, sand, quartz;
- 3, Mining processing industry: drying metal concentrates, slag, tailings;
- 4, Chemical industry: heat non-sensitive materials.
