Abstract
A powder circulating apparatus provides a closed loop system for delivering an absorbent media to an area adjacent a tire at which wearing of the tire surface is occurring, conveying away the absorbent media and those materials absorbed by or entrained with the absorbent media, and recirculating the absorbent media to the tire adjacent area. The apparatus advantageously permits the delivery of the absorbent media from one of a pair of spray locations so as to take advantage of the air flow adjacent the tire due to the direction of the rotation of the tire.
