Abstract
A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, including: a first sorting operation of sorting the two or more materials based on a grain size; and a second sorting operation of sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity.
Claims23
A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, the method comprising:
- a first sorting operation of sorting the two or more materials based on a grain size;
- and
- a second sorting operation of sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity, wherein the second sorting operation includes sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, by using centrifugal force or specific gravity difference;
- and
- a third sorting operation of sorting the materials, which are sorted by the first sorting operation or the second sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity again, wherein the third sorting operation includes sorting the materials, which are sorted by the first sorting operation or the second sorting operation and have the grain sizes belonging to the predetermined range, by using vibration,
- wherein the third sorting operation includes providing the materials, which are sorted by the first sorting operation or the second sorting operation and have the grain sizes belonging to the predetermined range, to a table having a slope based on any one axis among x, y, and z axes and generating vibration in a predetermined progress direction through a filler supply unit provided at one side of the table.
A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, the method comprising:
- a first sorting operation of sorting the filler into a first mixture of two or more materials based on a grain size, the first mixture having a grain size belonging to a predetermined range;
- a second sorting operation of sorting the first mixture into a second mixture of the two or more materials based on specific gravity, the first mixture being sorted into the second mixture using centrifugal force or a specific gravity difference of the two or more materials;
- and
- a third sorting operation of sorting the second mixture based on a specific gravity difference of the two or more materials, the second mixture being sorted using vibration,
- wherein the second sorting operation is performed by a spiral classifier having a predetermined slope, the second sorting operation including sorting the first mixture into a first component mixture and a second component mixture, the first component mixture including a first material of the two or more materials and the second component mixture including a second material of the two or more materials, the first material having a relatively smaller specific gravity than the second material, the first component mixture being sorted at a lower slope position of the spiral classifier than a center point of the spiral classifier, the second component mixture being sorted at a higher slope position of the spiral classifier than the center point of the spiral classifier, and
- wherein the second mixture includes the second component mixture.
A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, the method comprising:
- a first sorting operation of sorting the filler into a first mixture of two or more materials based on a grain size, the first mixture having a grain size belonging to a predetermined range;
- and
- a second sorting operation of sorting the first mixture into a second mixture based on specific gravities of the two or more materials, the first mixture being sorted using a specific gravity difference of the two or more materials or being sorted using centrifugal force;
- and
- a third sorting operation of sorting the second mixture based on the specific gravity difference of the two or more materials, the second mixture being sorted using vibration,
- wherein the third sorting operation includes providing the mixture to a table and generating vibration in a predetermined progress direction through a filler supply unit provided at one side of the table, the table being sloped with respect to any of x, y, and z axes.
