What is aluminum dross rotary furnace?

Aluminium dross rotary furnace is one kind of necessary equipment in the aluminum dross processing of recycled aluminum industry, which is one important part that reflects operation cost and profit of aluminum scraps recycling.

An aluminum rotary furnace is a specialized type of furnace used in the aluminum recycling industry to melt and process aluminum scrap into molten aluminum.

In the primary and secondary aluminum industry, aluminum scraps and aluminum ingot are melted in the melting furnace to get liquid aluminum, and a certain amount of aluminum dross is also generated.

ಸಾಮಾನ್ಯವಾಗಿ ಹೇಳುವುದಾದರೆ, the direct recovery rate from the furnace is roughly 88%-92% due to the different aluminum scrap materials.

A considerable amount of aluminum metal is mixed in the aluminum dross, and the aluminum dross skimming out of the furnace contains between 40-60% aluminum metal.

As for the recovery equipment for aluminum dross treatment, there are generally several types of equipment such as crucibles, vertical dross separator machine and rotary furnace.

The crucible has low investment and simple operation and is widely used in small-scale manufacturers.

ಆದಾಗ್ಯೂ, the disadvantages of crucible are very obvious, mainly in the following points:

1. The labor intensity is high, because the capacity of the ground furnace is small, and the efficiency of dross recovery is low. To process large quantities of aluminum dross, a large number of workers must be increased.

2. The recycling cost is high, and crucible, carbon coke, heating agent and other consumables are needed to process aluminum dross.

3. Fully manual operation, the recovery rate is uncontrollable.

4. The environmental protection is not up to standard, because there are many crucibles, it is not easy to apply the baghouse dust collector, resulting in dust flying all over the sky, the health of workers cannot be guaranteed, and at the same time polluting the workshop and surrounding environment.

ದಿ vertical dross separator machine is another effective machine for dross processing.

It adopts mechanized operation, automatic operation and less maintenance, with a dust collector.

The processing capacity (100-500KG per run), 10-15 minutes processing time, and more than 90% aluminium recovery rate.

Separate structure, top and bottom parts for the installation and transportation and maintenance.

Compare with the rotary furnace, the investment is less and the processing quantity is not so big as the rotary furnace.

Also, it can only process hot dross generated from the furnaces, not cold dross.

ದಿ ರೋಟರಿ ಕುಲುಮೆ is suitable for mass processing of hot dross, cold dross and aluminum dross containing big iron scraps.

The staffing is small, and only one skilled forklift operator and one auxiliary worker are needed.

It can process several tons to dozens of tons of hot and cold aluminum dross a day, and the work efficiency is extremely high.

The hot aluminum dross skimmed out from the furnace is sent into the rotary furnace with a rotary forklift, and the aluminum liquid in the aluminum dross can be separated by using the reverse rotation of the rotary furnace and the back and forth stirring of the forklift rake.

During the operation, attention should be paid to controlling the temperature, can add cold dross or small pieces of cast aluminum as temperature control agent and secondary refining.

After the treatment is completed, tilt the body of the rotary furnace with a hydraulic oil cylinder to pour out the aluminum liquid.

After the aluminum liquid is poured, rotate the body of the rotary furnace to unload the dross.

The operation is simple and convenient.

The recovery rate of rotary furnace can reach more than 80%.

If it can work together with the dross cooling and sieving machine, the comprehensive recovery rate can reach more than 90%.

Rotary furnace and dross cooling and sieving machine are ideal equipment to process aluminum dross and cold dross in large quantities.

Due to the centralized treatment, the generated dust and smoke generated in the dross processing with rotary furnace is convenient for centralized collection, which truly achieves energy saving and environmental protection.

Features:

Rotating Drum: The furnace features a rotating drum or cylinder where the aluminum scrap is loaded for melting. This rotating mechanism helps to mix and homogenize the scrap as it melts, ensuring uniform heating and melting of the aluminum material.

Refractory Lining: The interior of the furnace is lined with refractory materials to withstand high temperatures and protect the furnace shell from heat damage.

Burners: Gas or oil burners are used to generate heat inside the furnace, raising the temperature to melt the aluminum scrap.

Control System: A control system, typically computerized, regulates the furnace temperature, rotation speed, and other parameters to ensure efficient operation and consistent melting of the aluminum scrap.

Exhaust System: An exhaust system is integrated into the furnace to remove combustion gases and other byproducts of the melting process, ensuring a safe working environment for operators.

Aluminium dross rotary furnace technical parameter

1 Rotary furnace dross capacity and rotating speed

4.5 tons-5 tons aluminum dross can be done for 5 tons rotary furnace each time (in of them, hot aluminum dross is about 3.5T- 4 ಟಿ, the rest is cold dross), rotating speed: 1.5-2 R/Min

2 Processing time of rotary furnace

It will take 2- 4 hours to finish the processing.

The time will be different from the proportion of cold dross and hot dross.

3 Rotary furnace recovery rate ≥80﹪( the aluminum content in the hot aluminum dross is about 40-60%)

4 installed capacity 18.5Kw

Aluminium dross rotary furnace operation musts

1 Must check the refueling of rotary furnace supporting rollers often, equipped with oil pump for the machine, press “pump on” button in the control cabinet, the refueling pump can refuel at the time setting. If the refueling pump is damaged, change it to manual refuel, the refueling time interval is no more than one week.

2 Must check often the chain of rotary furnace main motor and foot bolts loose or not, If loose, should tight them immediately.

3 Must check upper and lower limit wheels of rotary furnace often, should turn with the rotary furnace rotation. If not, replace them immediately.

ಕಾರ್ಯ:

Melting Aluminum Scrap: The primary function of an aluminum rotary furnace is to melt aluminum scrap into molten metal. Scrap aluminum, such as aluminum cans, automotive parts, or industrial scrap, is loaded into the rotating drum of the furnace.

Heating and Mixing: The burners heat the interior of the furnace, raising the temperature to the melting point of aluminum. As the drum rotates, the scrap is exposed to the heat evenly, promoting efficient melting and mixing of the aluminum material.

Skimming and Purification: Any impurities or contaminants present in the aluminum scrap, such as coatings, paint, or dirt, float to the surface of the molten metal and can be skimmed off or removed using fluxes or other purification methods.

Casting or Transfer: Once the aluminum scrap is fully melted and purified, the molten aluminum can be cast into ingots, billets, or other forms for further processing or transferred directly to downstream processes such as die casting or extrusion.

ಅಪ್ಲಿಕೇಶನ್:

Aluminum Recycling Industry: Rotary furnaces are commonly used in aluminum recycling plants or foundries to process scrap aluminum into reusable molten metal. They play a crucial role in the recycling of aluminum materials, reducing the need for primary aluminum production and conserving resources.

Secondary Aluminum Production: The molten aluminum produced in rotary furnaces can be used to produce a wide range of aluminum products, including castings, extrusions, and rolled products, for various industries such as automotive, aerospace, construction, and packaging.

Foundries and Die Casting Facilities: Foundries and die casting facilities that produce aluminum components may use rotary furnaces to melt scrap aluminum for use in their manufacturing processes.

In summary, an aluminum rotary furnace is a versatile and efficient furnace used in the aluminum recycling industry to melt scrap aluminum into molten metal for further processing and production of aluminum products. Its features such as rotating drum, refractory lining, burners, and control system ensure effective melting and processing of aluminum scrap.
