The mechanical process of recycling does not use any toxic chemicals previously used in the process of extracting the valuable aluminium in the dross Hot dross processing system whereby the majority of metal is recovered without chemically reducing the aluminium oxides The dross is first crushed then separated into aluminium metal rich particles and aluminium oxide rich particles based on density
Hot dross in aluminium dross separating machine or in rotary furnace after refining molten aluminum is sparayed with water for heat exchange so that the 700900 degree high temperature aluminium dross can be cooled to normal temperature within 1015 minutes which prevents high temperature aluminium dross from burning loss or oxidation the classification screening can basically realize mechanical
Most of the remaining aluminium in the dross is recovered in a second stage through a meticulous mechanical separation process including the use of a nonferrous metal separator Recovered metal is collected remelted and sold or returned to the cast house
Using the thermite reaction of aluminum oxide hot dross generated in the aluminium melting furnace the system separates the aluminium oxide and molten aluminium metal by specific gravity with vane agitation The molten aluminium metal is then poured into an ingot case and the residual dross is classified and removed into a container
11 Definition of Dross and General Scope of Related Aluminum Recycling Aluminum Dross is a byproduct of Aluminum production Today much energy is consumed to recover the Al from the dross energy could be saved if the dross diverted and utilized as an was engineering material There are two forms of dross –white dross and black dross
Mar 19 2012 · Aluminium dross processor is a machine adopts foreign advanced technology no need for any fuel fast recovery which can made full use of the aluminum ash and scraps with high aluminum
May 01 2008 · Secondary aluminium dross is a waste material obtained from aluminium melting plants whose composition differs due to the various alloying elements used during remelting of the primary dross The dross used in this work was collected from a domestic dross producer which contains mainly around 65 alumina 4 SiO 2 and oxides of Mg Ca and Fe
An example of mechanical cleaning is the dry milling process Cold aluminumladen dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum Ball rod or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening
Mechanical cleaning includes the physical separation of aluminum from other scrap with hammer mills ring rushers and other machines to break scrap containing aluminum into smaller pieces This improves the efficiency of downstream recovery by magnetic removal of iron Other recovery processes include vibratory screens and air classifiers
