Secondary use of aluminum cans

Aluminum recycling generally prior principle is, first remove the mixed metals and other impurities, and then classified by ingredients, so in the alloy composition can be much use, the second is the surface of the oil, oxide and coating treatment of off, into a fit after charging conditions of furnace charge, get the economic and reasonable use.


It is usually handled in several ways:

1、heavy medium mineral separation method, the use of heavy medium gravity separation method to separate heavy non-ferrous metals such as copper density than aluminum, it USES the principle of aluminum density than other heavy non-ferrous metals, so that aluminum floating on the medium, and heavy non-ferrous metals sink in the bottom, to achieve the purpose of separation.

2、Parabolic dressing method can separate various waste non-ferrous metals with different densities in waste aluminum by using the principle that objects with basically the same volume fall at different points when being thrown out by the same force. When the same force is applied to shoot objects of different density and basically the same volume along a straight line, all kinds of objects move in the direction of a parabola and fall to the ground at different points. When the mixed waste materials run at high speed along the conveyor belt, when running to the end, the mixed aluminum is thrown out in a straight line. Due to the different gravity of various abandoned objects, they fall to the ground at different points, so as to achieve the purpose of waste aluminum separation. This method can separate aluminum, copper, lead and other materials evenly.
