First Claim
1. A method for processing and recycling infill material of artificial turf, the method comprising:
- drying extracted infill material through a fluid bed dryer;
processing the dried infill material using a vibrating screen to remove excessively large or small particles or unwanted matter;
separating the processed infill material by density; and
discharging the separated infill material.

Abstract
A method and system for processing and recycling infill material of artificial turf. The invention includes drying extracted infill material through a fluid bed dryer, the fluid bed dryer passes a process gas through a bed of solids via a perforated plate. The dried infill material is processed using a plurality of vibrating screens to remove excessively large or small particles from the infill material. The plurality of vibrating screens may be a set of progressively finer mesh screens. The processed infill material is separated by density. The density of the infill material may be determined by a high intensity, uniform sheet of laminar airflow. The separated infill material is discharged and is ready to be used again in another artificial turf. In one embodiment, the infill material includes at least one of graded sand, granulated styrene-butadiene rubber, cork, organic infill, thermoplastic elastomers, or ethylene propylene diene monomers.

11. A system for on-site processing and recycling infill material of artificial turf, the system comprising:
-
a drying component including a fluid bed dryer configured to dry extracted infill material, the fluid bed dryer passes a process gas through a bed of solids via a perforated plate; a screening component including a plurality of vibrating screens configured to remove excessively large or small particles from the dried infill material, wherein the plurality of vibrating screens are a set of progressively finer mesh screens; a separation component configured to separate the infill material by density using a high intensity, uniform sheet of laminar airflow, the separation component being mounted in-line at the end of the screening component; and at least two discharge components including a useable material discharge component for useable infill material and a unusable material discharge component for unuseable infill material, wherein the useable material discharge component transports the useable infill material to be used again and the unusable material discharge component transports the unusable infill material for disposal, and wherein the two discharge components are part of the screening component and the separation component. - View Dependent Claims (12, 13)
