Mineral slag dryer introduction:
Mineral slag dryer is widely used in building material, metallurgy, and

beneficiation, chemical engineering, and cement industries. It can be

used for drying of mineral slag, carbide slag, limestone, clay, river

sand, quartz sand, and grain slag. The mineral slag dryer is applicable

for many combustion furnace such as high temperature fluidized bed

furnace, coal dusting furnace and manual coal adding stove.

Mineral slag features:
Uses new type multi-combination type which solves the wind tunnel

phenomenon of the traditional dryer and is of high heat efficiency. The

coal consumption is decreased by about 20%.

Mineral slag application:
It is applicable for drying of mineral slag, limestone, clay, river

sand, quartz and, grain slag, coal slurry, and slurry that is of heavy

wetness, and big specific weight.

Mineral slag dryer working principle:
1. The material is sent to hopper by belt conveyor or bucket elevator,

and then enter into the feed end by the charging pipeline of the

charger in hopper.
2. The charging pipeline gradient of fluorite dryer equipment should be

bigger than the natural gradient of material so that the material can

enter into the dryer smoothly.
3. The dryer cylinder is a spin cylinder of little tilt to the

horizontal line. Material goes in from the higher end, the heat-

carrying agent enters from the lower end contacting with the material

in countercurrent way. The wet-material is heated directly or

indirectly by the heat-carrying agent during its moving forward process

in the fluorite dryer equipment, and thus it is dried.
4. Then it is sent out by belt conveyor or spiral conveyor on the

discharge end. 5. There is shoveling plate on the fluorite dryer inner

wall, lifting and dropping the materials to enlarge the contact surface

of material and air current and speed up the drying process and promote

the material moving forward. The heat-carrying agent can be divided

into hot air and flue gas.
6. After the heat-carrying agent entering into the dryer, cyclone

collector is needed to gather the material in the air. To further

reduce the dust load in tail gas, the bag filter or dust washer is

needed.

Mineral slag dryer production line consists of rotation barrel, induced

air equipment, high speed scattering equipment, automatic cleaning

device, transmission device, conveying device, blast heater, speed

reducer, supporting device and sealing devices. The whole set drying

device is of reasonable design, fine making, stable property, advanced

technology, high output, low energy consumption, small floor area, and

high mechanic degree.
