3 methods for Aluminium dross recovery
Aluminum dross is one kind of by-product of aluminum industry, aluminum content from that will share 1%-12% of the total loss in the aluminum production process.
Recovery aluminum from aluminum dross can reduce the cost, protect the environment, save energy and improve resource utilization, which has big economic and social benefits.
1. MRM method (Metal recycling machine)
It is also called as aluminium dross machine(ADM), this process is sending hot aluminum dross generated from the melting furnace to the machine with the dross trolley, making the liquid aluminum stirring in the pot of aluminium dross machine, adding heating agent into the machine to make the aluminum dross keep requested temperature, then aluminum will be extracted from the dross.
The processed aluminum dross can be further sieved, pulverized, melted and recovered for the second recovery processing.
The recovery rate can be 91% and the burning rate of aluminum can be reduced to 4%.
Our aluminum machine belongs to this type of dross machine and it has a high recovery rate, no need any fuel and a short working time, processing 100-500 kgs aluminium dross in 10-12 minutes.
2. The pressing recovery process method
Press 15Mpa pressure on it, the liquid metal of slag will flow down to the lower container under the pressure; the oxidation of slag that is pressed will be ended, the oxide will be muffled in the metal shell.
At the same time, the metal shell of slag will transfer the heat to the pressure head and slag tray, the cooling water of the pressure head will take away lots of heating, which will make the slag temperature reduced from more than 800℃ to below 450℃, to prevent the oxidation of metal because of high temperature.
3. ALUREC Method
Rotary aluminum melting furnace, Oxygenenrichment natural gas as the fuel, can get to high temperature in a short time.
Liquid aluminum lay down the bottom of the melting furnace; Non-metallic slag will float on the top of the melting furnace.
The method is featured with high efficiency, low energy consumption, good running environment.
Pure oxygen will be used as an oxidizer effective to reduce the organic gases generated in the combustion process.
Gas hoods can effectively recover the other dust, with high efficiency, high degree of mechanization and good running environment advantages.
The shortage is the residual aluminum dross that needs to be further processed.
