Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..

There is a reasonably good relationship between fabric weight and denier for a given weave, enough that people have no difficulty recognizing 200D fabric as a packcloth and 1000D as luggage material. But different weaves (or mill processing) can produce different fabric weights from the same size denier yarns.
