Aluminum Dross Recycling Briquette Press Machine And Process
What is aluminum dross briquette
Use briquette machine to make briquette is a kind of way in aluminum dross circulation. This method is with low investment and quick effect. It is a reasonable utilization of the drossing treatment of aluminum ash.
Why make aluminum dross briquette
- The converter molten steel should be refined. No matter which kind of refining processes we have chosen, after the molten steel output from the converter, the modification of the top flux is necessary.
- Aluminum-based modifier is suitable for this usage. The aluminum element is used as a deoxidizer to adjust the physical and chemical properties by deoxygenating for the molten steel as well as the converter flux.
- Other materials are also added in the briquette to make the briquette with other functions of adjusting the alkalinity and viscosity, etc.
The aluminum dross sources
Aluminum dross (other names as aluminum ash or aluminum slag) is a kind of solid waste from the aluminum making process.
Mainly there are three of it:
- In the process of producing aluminum by molten salt electrolysis, a certain amount of aluminum dross will be produced due to the operation and measurement of the carrying, anode replacement, aluminum ouput, and ingot casting, one ton aluminum oxide will produce about 30 to 50 kg of aluminum dross;
- During the casting process, aluminum will also produce aluminum ash due to ingot casting, multiple remelting, alloy preparation, component casting, or forging, extrusion, rolling, and cutting. The process produces aluminum dross for about 30 to 40 kg per ton product ;
- Aluminum dross will also be produced during the process of recycling aluminum scrap. The recovery rate of scrap aluminum recycled and reprocessed into products is generally 75% to 85%. Recycling one ton aluminum dross will produce more than 100 kg extra aluminum dross.
Make aluminum dross as a flux modifier
- Use an aluminum dross briquette machine can turn this material to briquette for further usage.
- The aluminum dross should be mixed with other materials and additives and then make the briquette. Normally, the briquette is used as flux modifier in furnace (the aluminum-based modifier).
Aluminum dross briquette press machine
- The hydraulic roller briquette press is used to make aluminum dross briquette.
- Hydraulic roller briquette press is a kind of briquette machine with easy pressure adjustment system. Thanks to the high pressure, materials can be briquette with a very low moisture.
Process of aluminum dross flux briquette making
Before making the briquette, the aluminum dross should be mixed with other materials (like quicklime, etc) with proper rate, then the briquette can be made by the briquetting machine.
General process as follow
- Raw material ⇒ Crushing ⇒ Mixing ⇒ Briquette
- Raw materials first are crushed to get a certain size range.
- After crushing, materials input to the mixer with a proper rate, there in the mixer (wheel mill), these materials are stired and pre-compressed, make the material with proper size and reduce the gaps between the particles, further improve the quality of briquette.
- The briquette making under a suitable pressure, raw material come through the briquette press and output by briquettes with suitable size.
- Things should pay attention to improve your briquetting work.
Iron removal
In order to prevent damage to the system from iron, an installation of iron removal device is more reasonable, which will help to increase wear resistance and fatal damage (large iron).
Conveying system
The addition of the ration silo in the middle of the whole conveying system can ensure a uniform transportation of the raw material, prevent damage of the briquette machine (roller, motor, etc.). Due to the instability of the feeding, it will reduce the excessive energy loss and decline of finished product.
Rate and size of raw materials
The size of raw materials should be controlled in a certain range for a better briquette performance. Different material can be in different size ranges. The material in big size with small amount acts as a skeleton of the briquette.
The briquette storage packing
- There are many types of packing machines, like the powder filler machine, liquid packing machine, and solid packing machine, but in briquette making process, the best choice for us is an exact packing machine named tons packer for our large capacity and usage.
- Due to the characteristics of the briquette, long-term storage is prone to chalking, seal the product or pack it with packing machine will multiples the storage time.
Aluminum dross is a mass of solid impurities. These impurities float on molten metal. It usually appears on the melting of low melting point metals or alloys. It can also be obtained by oxidation of the metal. Aluminum dross can be mechanically recycled to separate the residual Aluminium metal from the Aluminium oxide.
Aluminum dross ranges from 1-2% of the Aluminium manufactured and comprises 30-70% Aluminium by weight. You will be amazed to know that 1 tonne of Aluminium metal production generates 10 to 20 kg of dross. Currently, in India, there is very limited processing of dross in an organized manner. The world produces approximately 65 million tonnes of Aluminium per annum, which results in approximately 1 million tonnes of aluminum dross being produced every year. Furthermore, out of which ~100k is produced in India. Hence, the environmental impact of this waste is a global problem that needs to be addressed on priority.
Mechanism
For aluminum dross processing, we need to know its mechanism in detail. Firstly, it is formed as a by-product during the extraction of aluminum. Secondly, aluminum dross can be wet and dry.
Waste aluminum dross consists of metallic and nonmetallic substances, like alumina, nitride, carbide, salt metal oxide, etc. In this process, aluminum dross is produced. It is an oxide film structure over metallic aluminum. At the point when the liquid aluminum interacts with atmospheric oxygen. This oxide item is called aluminum dross. It is physically expelled away from the liquid aluminum. It is a blend of metallic aluminum entangled in alumina and salt transitions utilized in smelter plants. The range of basic and auxiliary dross delivered per tonne of liquid metal is approximately 1.5% to 2.5%. Also, per year the range is up to 8% to 15%.
- So now let's talk about Types of Aluminium Dross!
- There are two kinds of dross.
- Non-salt is known as white dross.
- Salt-containing is known as black dross.
White dross contains a high percentage of an aluminum substance such as Al, Al2O3. Also, it is delivered from essential and optional aluminum flux. White dross consists of a large amount of metallic aluminum substance. It's up to 15 to 75%. It consists of fine powder separated from the liquid aluminum. But in the case of black dross, it consists of a low amount of metal substance. Also, it is created at the time of secondary aluminum refining processes. Black dross involves a mix of aluminum oxides and slag. Although, with recoverable aluminum content in the scope of 12–18%. And greater salt substance, for instance, higher than 40%, stood out from white dross.
Now, you know that waste aluminum dross consists of metal and non-metal. It is developed when molten aluminum reacts with atmospheric gases and its outer surface. White dross is produced during the elementary aluminum fabrication process. It is marginally unsafe and is all valence in the optional steel industry or ancillary Aluminium formation. The aluminum dross having a low amount of metal composition, which is somewhere in the range of 5–20 wt% of the whole weight of trash is known as secondary dross. The coarse grain or secondary dross mainly contains high amounts of salt and gas expansion compared to the compact or primary dross. The coarse grain dross has a bulk density in between the range of 0.79 to 1.11 g/cm3. So if the quantity of metallic compound increases, then the bulk density of dross decreases because the specific gravity of aluminum material is lower than its oxide form.
