We has spent my spare time to study the aluminum dross recycling for 6 years and visited many Chinese aluminum foundries,I found the best solution to recycle aluminum dross is hot dross recycling because the aluminum dross would oxidize easily under the air and hot condition for long time. There is one more thing, as we know, when the aluminum smelting, we would feed some refining agent, fluxing agent or covering agent into the melting furnace, these agent will make the aluminum dross contained the K, Na, Ca chloride, if you use the nitrogen filling into the aluminum liquid, it will generate AIN, so if , if the aluminum dross in the presence of water, it will generate the pungent smell ammonia gas, or hydrogen, methane, will cause poisoning or firing.
I recommend an equipment of aluminum hot dross recycling machine here.The working principle of aluminum hot dross recycling machine: take advantage of high temperature situation of the aluminum dross which come from aluminum melting furnace or holding furnace and separate the aluminum fluid and the aluminum waste dross. The stirrer can rotate forward and reversely as well as up and down automatically. Just use the trolley (the dross feeder for transport the hot aluminum dross from aluminum melting furnace to holding furnace) to send aluminum dross to the heat pot of dross machine, then press the button of control panel, the hot dross recycling machine will run automatically. There is a small dust collector can collect the smoke when the machine running, you can connect the dust collector to your big bag type smoke removing machine. The recycled rate of this machine can up to 90%. This machine can be equipped with dross cooler, grinding unit and segregating unit to get higher recycled rate.
Except the big aluminum smelters, most aluminum extrusion factories have their own aluminum billet casting plant or the small aluminum melter to make ingot or die casting, one set of aluminum hot dross recycling machine will be enough.The Min. Model machine, the dross loading pot of 900mm can process 100~150KG in 12~15 minutes. Small aluminum dross capacity no need the dross cooler because big capital investment and large space occupy. This machine has a small dust collector and there is an exit on the dust collector which you can connect to your own dust collector for melting furnace. This machine structure is simple, we will not send technician to buyers' factory to installation to help client to save their budget. But I will supply the equipment installation, operation guidance, use the pictures to explain, send it by PDF document. We has exported this machine to Thailand, Brazil,Mexico, Russia,Kazakhstan and Vietnam. We has rich experience on the after sale service. Meanwhile, If you have any doubt, send me video, pictures and describe details, I will show to engineer and give you back the solution. And I will keep on improving our after-sale service system.
