Abstract
A method of sorting a mix of scrap material to separate out magnesium scrap from the mixed scrap for reuse is presented herein. The method includes using sensors to detect characteristics of the scrap material and sorting or separating the scrap material into the different types based on the detected characteristics from the sensors.
Claims19
A method of sorting mix material scrap to separate out magnesium scrap from the mixed material scrap for reuse, the method comprising:
- providing a mix of scrap material consisting essentially of aluminum and magnesium scrap,
- wetting the mix of scrap material with water to cause the magnesium scrap to turn blue in color,
- using a first set of sensors to detect a color and a density of each piece of scrap in the mix of scrap material after wetting the mix of scrap material with water,
- removing any piece of scrap from the mix of scrap material if the detected parameters associated with each piece of metal scrap does not meet a first criteria set to provide rough-sorted magnesium scrap,
- while the rough-sorted magnesium scrap remains wet, using a second set of sensors to detect the color and the density of each piece of scrap in the rough-sorted magnesium scrap after removing any piece of metal scrap from the mix of scrap material based on the first criteria set, and
- removing any piece of scrap from the rough-sorted magnesium scrap if the detected parameters associated with each piece of metal scrap does not meet a second criteria set that is different from the first criteria set to provide a final product of fine-sorted magnesium scrap for reuse.

A method comprising:
- providing a mix of scrap material consisting essentially of aluminum and magnesium scrap,
- wetting the mix of scrap material with water to cause the magnesium scrap to turn blue in color,
- using a first sensor to detect a color of each piece of scrap in the mix of scrap material after wetting the mix of scrap material with water, and
- removing any piece of scrap from the mix of scrap material if the color detected by the first sensor meets a first predetermined blue color.

A method comprising:
- providing a mix of scrap material consisting essentially of aluminum and magnesium scrap,
- wetting the mix of scrap material with water to cause the magnesium scrap to turn blue in color before removing any piece of scrap from the mix of scrap material,
- using a first color camera sensor to detect a color of each piece of scrap in the mix of scrap material after wetting the mix of scrap material with water, and
- removing any piece of scrap from the mix of scrap material if the color detected by the first color camera sensor does not meet a first predetermined blue color,
- using a first x-ray sensor to detect a density of each piece of scrap in the mix of scrap material, and
- removing any piece of scrap from the mix of scrap material if the density of the piece of metal scrap detected by the first x-ray sensor does not meet a first predetermined density to provide rough-sorted magnesium scrap.
