Aluminum dross tilting rotary furnace is suitable for mass treatment of hot slag, cold slag and aluminum dross containing high iron. The number of people is small. Only one skilled forklift worker and one auxiliary worker can handle several tons to dozens of tons of hot aluminum slag a day, and the work efficiency is very high. The hot slag raked out from the furnace is sent to the rotary furnace with a rotary forklift. The aluminum molten in the aluminum slag can be separated by using the backward rotation of the rotary furnace and the front and rear mixing of the forklift rake. Pay attention to controlling the temperature during operation. Cold slag or small raw aluminum can be added as a temperature control agent and secondary refining. Rotary furnace and screening cold ash bucket are ideal equipment to replace crucible and vertical ash recycling machine to deal with aluminum slag and cold slag in large quantities.

The aluminum dross rotary furnace does not need heating device for the treatment of hot slag and cold slag. In particular, when dealing with cold slag, it can be operated continuously only with a bucket of hot slag raked out from the furnace. In addition to the electric energy of equipment operation, there is no additional energy consumption in the operation process. Due to the centralized treatment, the generated dust is convenient for centralized collection, which truly achieves energy conservation and environmental protection.

Applications:

• Secondary aluminum production: Processing dross generated from recycled aluminum sources.
• Primary aluminum smelters: Treating dross generated during initial aluminum production stages.
• Foundries: Recovering aluminum from foundry dross for remelting and incorporation into new castings.

Advantages of aluminum dross tilting rotary furnace:

This equipment recycles and reuses the ash raked out of the smelting furnace. The rotary furnace is used in a plant that processes slag in large quantities. After treatment, it can also be put into your ash cooler for cooling and sorting. The sorted ash is fine, medium and coarse. The fine ash can be directly sold out. The medium ash and coarse ash can be added into the rotary furnace and returned to the furnace as coolant, which can make the recovery of aluminum slag aluminized, and the economic benefit is very obvious.

Equipment features of aluminum dross tilting rotary furnace:

• High temperature control precision;
• High degree of automation;
• Low energy consumption, high yield and low pollution;
• Continuous production.

Application skills of aluminum dross tilting rotary furnace

• Aluminum dross tilting rotary furnace shall be paved with cold ash before use. The bottom cold ash shall be the screened ash granular material with the addition amount of 3/4 to 1 bucket. If the amount of hot ash is not enough, hotter ash can be added.
• The hot ash sent from each workshop shall be put into the furnace in time (except for being recycled or unloaded). If it cannot be put into the furnace in time, the hot ash burned on the surface shall be dispersed and covered with fine ash, and the slag basin cover shall be used to close, so as to prevent excessive oxidation and reduce heat loss.
• Furnace loading:
  • The total weight of cold ash and hot ash shall be considered during furnace loading. The ratio of cold ash to hot ash is approximately 2:3, in which the cold material is generally not more than 1.5-3 tons, the hot ash is not more than 3-5 tons, and the total ash loading per furnace shall not exceed 8 tons.
  • When the amount of hot ash is enough, it can start to work. Use the forklift to rake dross to make it heat up evenly.
  • Use the remote controller to control the rotation of the rotary furnace (forward rotation or reverse rotation) and stir with the rake at the same time. The control temperature should not be too high (when the temperature is too high, add cold ash to cool down)
  • When adding materials to the aluminum slag tilting rotary furnace, the ash hopper shall not hit the furnace door and furnace wall violently, and the charging time of each hopper is 3-5 minutes.

The process of aluminium rotary furnace

The process of aluminum dross in the rotary furnace is inside heating, it means that we use the heat coming from aluminum dross self-ignition (during the high-temperature period of self-ignition, waiting for the heating between the stirring of high-temperature aluminum dross ), so that can improve the melting speed of aluminum and aluminum liquid temperature, reduce aluminum viscosity, easy for the separating aluminum liquid and aluminum ash.

Aluminum dross rotary furnace can extract aluminum metal in the aluminum dross from 40-60% to 15-17%, with a high aluminum metal recovery rate (about 80%).

The dust generated in the production process gets controlled, not only reduce the working strength, but also improve the dross processing environmental pollution.

Heating method:

Common heating methods include electric heating, gas heating, fuel heating, etc.

Select the appropriate heating method based on energy supply, cost and requirements.
