As we all know, the main component of aluminum dross is aluminum oxide, aluminum liquid and aluminum dross has good adhesion, at the same time a large number of aluminum liquid will be taken out, and due to the high temperature of aluminum dross, aluminum liquid in the air produced secondary oxidation, resulting in a large number of metal losses, which leads to increased costs of enterprises at the same time, but also caused environmental pollution. The aluminum dross press solves this problem, which is an efficient and environmentally friendly way to treat aluminum dross.
How an aluminum smelter who have rotary furnace to using salt cake dross press to optimize the dross?
If you are an aluminum smelter and you have rotary furnaces, we would like to share the following information:
An rotary of 10Mt capacity we assume the salt cake generation is about 3 - 4 MT per load. Certainly an dross press would bring up the recovery of this material for you mechanical separation process. It would move the recovery on your site from 7% to 12 - 15%. The remaining salt slag would still have some aluminum in it for the current buy closer to the 5% than the 7%. The press would gain these extra metal until by both the rapid cooling process and the plating process of coalescing the droplets of aluminum that are now distributed on thru out the salt cake.
Our salt cake dross press Model 160 is suitable for the above application. The pressing process is designed to quickly cool the salt cake to reduce the dross temperature quickly below 350oC, to stop secondary oxidation and coalesce the aluminum particles in the salt cake, saving more aluminum in the dross and improving the overall aluminum recovery. Usually you would have an improvement of easily 5 -10% on aluminum content in the dross and most likely more.
Aluminum dross press is currently very popular in the aluminum industry, it is indeed an efficient, environmentally friendly, safe, no waste aluminum recycling equipment, the use of slag press to press the aluminum dross and cut off the air at the same time, the aluminum dross also to achieve forced cooling, accelerate the solidification rate of aluminum liquid aluminum dross, this method greatly reduces the dust in the treatment process, and the loss of metal. However, the dross press treatment, the on-site aluminum output is uncertain, can only reduce the loss, but also need follow-up cold slag treatment, in order to achieve the highest metal recovery.
In short, the aluminum dross press can maximize the amount of aluminum recovery, cost effectiveness, environment, improve product quality, versatility and reliability.
We are looking forward to you consult with us and we would like to give you the optimization solution for the dross and save a lot money for you. Welcome to come us dross press at tech@huan-tai.org.
