The problem is aluminium is made up of hundreds of different alloys and these alloys could never be cleanly separated from each other until now when scrap aluminium was melted down for recycling large amounts of primary aluminium had to be added in order to create the right mixture for various aggregates Metal Corner Brackets the correct alloy for window frames and related products for example but the production of primary aluminium from the raw material bauxite is extremely energy-intensive so if new window frames can be made from old ones without additional primary aluminium that would not only save a considerable amount of material but large amounts of energy as well this is exactly the challenge faced by engineers in Gaul Magan who have created a new recycling facility their goal is to not only separate plastics and other metals from the old aluminium frames but also from aluminium alloys containing heavy metals that are unsuitable for the production of window frames in the first part of the process shears.

And the conventional shredder cut up the frames magnetic separators and eddy current separator x's then extract the metal screws and hinges as well as rubberwood and plastic from the material flow the resulting shredder waste is almost entirely made up of aluminium but it also contains scraps of aluminium that do not belong in the window frame alloy such as old aluminium window handles and rivets sorting out these unsuitable materials is the job of a special x-ray machine Adam pretty conventional shredder race does not provide us with efficient sorting quotas for our x-ray machine the innovative aspect of our second shredder phase is that were shred and sipped the material giving it an optimal preparation for our x-ray transmission machine unlike the first shredder the second one does not pound the scrap metal with hammers special blades cut the coarse aluminium parts into chips measuring some four to six centimetres aluminium is an extremely abrasive material.

That wears out other metals so the blades are made of specially hardened steel the to shear shredders are able to produce corner Brackets than 100 tons of aluminum chips per day the subsequent screening unit filters out the smaller parts the result is a material flow with nearly homogeneous geometry this makes the detection of individual fragments possible in the x-ray machine that follows but unsuitable Outdoor Screws alloys containing high levels of copper or zinc can still be found on this conveyor belt a special sorting unit separates these fragments to powerful x-ray sources with the energy of 160 kilo electron volts examine the individual parts to protect the workers from high levels of radiation the unit is covered with a heavy lead she made the aluminum chips evenly cover a corner Brackets than 2 meter wide conveyor belt it carries the chips at a speed of four meters per second the x-ray lamps examine them from above the x-ray detector under the belt measures the incoming radiation the corner Brackets unsuitable heavy metals such as copper and brass that are found in the aluminum scraps.
