A brief introduction to slag dryer

The slag dryer is the main equipment for drying the slags with certain moisture. The equipment consists of the rotary barrel, induced fan system, dispersing system, lifting blade, self-cleaning system, transmission system, conveying system, reducer, supporting system, and sealing system.

Slag dryer

Slag dryer

All the parts are designed scientifically and reasonably. Fote slag dryer has a good energy-saving performance, high production efficiency, and great production benefits.

Except for drying the slags produced in the smelting plants, the slag dryer can also be used to dry acetylene sludge, limestone, clay, river sand, quartz sand, etc.

Fote slag dryer's advantages

1. High drying efficiency

Fote slag dryer has a high capacity, strong anti-load strength, and high running efficiency, which brings more economic benefits to the slag recycling plant.

2. High feeding and discharging performance

Fote adopts new feeding and discharging port in slag dryer to prevent the drying machine from blockage, material returning, and uneven feeding. Furthermore, it can efficiently reduce heat loss though a good sealing system.

3. Stable running status

The slag dryer produced by Fote Machinery adopts a new type of barrel structure to make it more suitable to materials. The wear-resistance of the barrel and the production efficiency have been improved, so the equipment operates more reliably.

4. Good drying performance

The lifting plates with multiple shapes are installed on the inner wall of the slag dryer barrel to increase the contact surface between the material and the hot airflow, thereby bringing more working efficiency and higher drying performance.

Slag dryer' applications

Due to advanced internal casting techniques, slag dryers are widely used to process alkaline slags, acid slags, and other industrial raw materials.

Alkaline slags: yellow feldspar, dicalcium silicate, olivine, wollastonite, spinel, etc.

Acid slags: pseudo-wollastonite, pyroxene, plagioclase, perovskite, anorite, titanium pyroxene, bayiite, etc.

Other industrial materials: river sand, copper ore, pyrrhotite, hematite, limonite, molybdenum ore, gold ore, iron ore, limestone, clay, etc.

Slag dryer's applications

Slag dryer's applications

**Several materials' applications after drying

1 Slag

Slag can be used to produce construction materials such as slag cement, slag bricks, blocks, slag concrete, thermal insulation materials such as slag wool, and other inorganic non-metallic materials such as glass ceramics after drying.

2 River Sand

This material is mainly used in the construction field. River sand has high humidity that makes a lower utilization value. However, it can be better applied after drying.

3 Lignite

Lignite is a kind of natural coal ore. The comprehensive utilization value of unprocessed lignite is extremely low because it produces much sulfur dioxide. After being processed by the slag dryer, lignite can be used more efficiently.

4 Clay

Clay can be used for processing lightweight aggregate after drying. And the clay products are low-cost and have broad commercial prospects.

Slag dryer's working principle

The slags are sent into the feeder hopper by a belt conveyor or bucket elevator. The dryer cylinder is a rotating cylinder with a slight incline to the horizontal line.

Slag dryer's working process

Slag dryer's working process

The materials are sent out from the upper end and the heated airflow is sent out from the lower end. Both of them are mutually in contact with each other. With the rotation of the cylinder, the action of gravity will completely move some heated airflow with the materials into the end of the barrel.

In the advancement of the barrel, the wet materials directly or indirectly gain the heat of the airflow and get dried. Finally, the dried material is discharged from the barrel and sent into the warehouse for further recycling.

The slag dryer has worked well with high drying efficiency, stable working status, saving more cost, and bringing many partners for me.

Slag dryer's maintenance tips

  • During the operation process, the barrel and liner should be checked after 6 to 8 hours.
  • The operator shall monitor the running status regularly. By the way, the operator should have training in advance.
  • The parts such as the main engine, transmission system, and bearing should be checked and cleaned after being put into use for about 6 months.
  • The main engine should run stably and the temperature in the bearing house should be no more than 50℃ for the first using time. After testing for 30 minutes, the parts should be fixed tightly.

Frequently asked questions of slag dryer

Why is the feeding port blocked in production?

Because the slag has a certain humidity and the particle size is not uniform. Under these conditions, it is easy to cause clogging and even the burning out of the lifting plate. There are two tips to solve this problem:

1. The operator should check the feeding status to avoid the bulk of slags from entering into the slag dryer.

2. The thermocouple should be installed at the flue pipe to monitor the temperature.

Why is a crackling sound inside the slag dryer?

There are two reasons: first, the material in the dryer is blocked; and second, the temperature of the dryer is too high, causing the burning inside the equipment.

When the material is blocked, we have to immediately shut down the machine for cleaning. When the temperature of the dryer is too high, we must reduce the fuel supply, so that the temperature of the equipment is reduced to meet the production requirements.

What should we do if the dried material cannot meet the humidity requirement?

First, please control the feeding volume. Second, check the inside status of the dryer. Finally, increase the heat supply.
