Aluminum ash ball mill production line processing process
Aluminum slag is produced during aluminum smelting, and some impure mixed metals are slag, but there is still a certain amount of aluminum, which can be separated and refined to obtain part of aluminum. This technology is established in the research of industrial smelting waste slag treatment projects, and the treatment process of aluminum ash The process and equipment are developed, and a mature aluminum ash treatment system has been launched. The aluminum ash treated by the aluminum ash separator and the cold aluminum ash that has not been separated can be crushed, screened and melted. Until it is cast into a finished aluminum ingot, the aluminum ash is treated quite cleanly.
Aluminum ash is produced in all processes of molten aluminum, mainly including: primary aluminum production (electrolytic aluminum), aluminum alloy production, waste aluminum recycling and aluminum ash treatment. Usually, according to the different aluminum content in aluminum ash, it can be divided into It is primary aluminum ash and secondary aluminum ash. The aluminum slag removed from the smelting furnace is called primary aluminum ash, which is gray-white in appearance, mainly composed of a mixture of metal aluminum and aluminum oxide, and the aluminum content can reach 15%~ 70%, also known as "white aluminum ash"; secondary aluminum ash is the waste after primary aluminum ash extraction of metal aluminum, the main components are alumina, aluminum nitride, metal aluminum, salts and other components. It consolidates into lumps, also known as "salt cakes".
The aluminum ash treatment process system adopts crushing-screening-ball milling-screening (separating aluminum particles with a particle size of 2~3mm)-returning to the furnace (when the product requires low iron, iron should be removed before entering the furnace), namely Can produce excellent results. Since the aluminum ash treatment method is a dry system, the dust is relatively large. Therefore, the whole system needs to be closed, add a dust cover, and configure a cyclone dust collector to ensure a normal working environment. It can also be connected with hot ash treatment, which can improve efficiency. The treated aluminum pellets can be directly used for smelting. Aluminum ash can be used as the raw material for the production of aluminum chloride series water purifiers, so that the recycling of waste aluminum can make the best use of it. Or use the treated aluminum ash to make the joint material instead of cryolite for the raw material of electrolytic aluminum. The throughput varies depending on the configured machine.
The specific steps of the aluminum ash treatment process:
1. Broken
The recycled aluminum slag and casting waste sand are transported to the ball mill through the silo and closed conveyor for crushing.
2. Ball mill
The aluminum ash slag that has undergone the crushing step is further ball-milled.
3. Screening
Sent to vibrating screen for sieving.
4. Use
The sieved materials are divided into aluminum scraps/granules and powder (secondary aluminum ash). The furnace is made into aluminum ingots and sold out. The remaining powder (mainly containing alumina) is sent to the cement plant as an auxiliary material.
Note: The aluminum ash treatment process should ensure that the entire recycling process is safe and dust-free, and will not cause secondary pollution to the environment.
At present, the aluminum ash treatment process using aluminum ash ball mills to grind and dispose of aluminum ash slag on a large scale uses aluminum ash slag as one of the raw and auxiliary materials for manufacturing cement, and the technical route is relatively mature.
