Slag Dryer

The slag drum dryer is an industrial drying equipment that reduces the moisture content of slag, making it easier to handle or reuse. This process is crucial for waste management and potential further applications of slag.

• Dried Moisture(%): 12-15% (Adjustable)
• Capacity: 300-3000 t/d
• Heat Source: biomass, natural gas, diesel, coal, etc.
• Application: Widely used in cement, mining, building materials, chemicals, metallurgy, slag, clay and other industries.

Over 200 Exported Countries: England, Zimbabwe, Mongolia, Ukraine, Indonesia, Mexico, South Africa, Albania, Tonga, Canada, Italy, Pakistan, Philippine, etc.

Introduction of Slag Dryer

To recycle slag produced in ore dressing or smelting industry, Zoneding Machinery develops new advanced dryer for slag drying. Zoneding slag dryer machine is commonly used in building materials, chemical industry, cement, etc. Mainly composed of rotary cylinder, lifting blades, self-cleaning device and other equipped devices, slag dryer, or slag drying machine operates stably as well as is of mature technology, high production capacity and efficiency.

√ High temperature fluidized furnace

√ Pulverized coal duster furnace 

√ Artificial coal furnace.

Applications of Slag Dryer Machine

Thanks to its own cleaning device and material lifting plate, slag dryer is extensively applied to dewater wet materials with large specific gravity.

1. Slag dryer is mainly used in smelting field like iron industry for the tailings of blast furnace slag drying;
2. In cement industry, the slag dried by the slag drying machine is milled into powder and is used as the raw materials in cement and concrete production;
3. Slag dryer is also be used in building materials production and as the raw material in chemical industry.
4. Other applications: slag dryer is used for drying carbide slag, granulating slag, limestone, metal powder, clay, river sand, coal slime, sludge and other materials.

Applied Fields of Slag Dryer

How Slag Drying Equipment Works

Co-current heating mainly works in slag drying process. Wet slag is transmitted into the cylinder by the feeding box and feeding conveyor. Then it is pushed back to the other end of the cylinder of the drum by spiral blades inside. The dryer is set at a certain angle. On one side, the wet slag flows down to the exit under the effect of gravity and rolling. On the other, it is brought up to the top end of the cylinder by the blades and falls into a screen to get in full touch with the scorching wind. Thanks to this repeated proceeding, wet slag is dried step by step.

Structural Advantages of Zoneding Slag Dryer

Slag Dryer Machine Structure

Slag dryer is also a kind of rotary dryer, which is mainly composed of a rotating cylinder, induced draft fan, high-speed scattering equipment, lifting plates, self-cleaning device, transmission device, conveyor, hot air equipment, reducer, supporting device, sealing device and other components.

Structure of Slag Dryer

• Slag dryer can meet different particle size and moisture need of slag, fly ash and other materials.
• Large processing capacity, strong anti-overload capacity, low fuel consumption, which can reduce the drying cost.
• Concurrent flow drying design is adopted  to achieve the best drying effect. Material and heat flow enter into the drying equipment from the same side. The dryer outlet temperature is low with high thermal efficiency.
• New kind of feeding and discharging device to prevent the feeding jam, discontinuous, inhomogeneous and feeding returning phenomena, which reduces the load of the dust collecting system.
• The innovation of inner structure strengthens the cleaning and heat transfer effect of dispersed materials and eliminates the sticking phenomenon of the inner cylinder wall.

How to Prolong Slag Drying Machine Service Life

The key to extend the service life of the slag dryer is to do often maintenance and check. Based on experience, Zoneding engineers give some tips for reference.

1, Bearings take all the load of the machine. Therefore, satisfactory lubrication is much concerned with the service life. Lubricant oil infused shall be clean and the container shall be sealed well;

2, Frequently check the newly installed tyre, which is easily loosed;

3, Pay more attention to the easily-worn parts and be ready to replace those need to;

4, Pay much attention to the oil temperature of the bearing parts. Put an end to the dryer immediately, if it goes up higher. Find the cause and figure it out.

5, An impacting sound from the rotating wheels shall call your attention to stop this drying machine. Immediate check and solutions are needed.
