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:

This equipment makes great changes in the lift flitch devices, adopting 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 20%.

Mineral slag application:

It is applicable for drying of mineral slag, limestone, clay, river sand, quartz and, grain slag, coal slime, and slime 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 equipment:

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.
