To this shaft arms are attached which stir the kaolin into a finely divided slip. From the washer the kaolincharged water passes to the sand wheels, which are shown in connection with the washers in Fig. 18. These sand wheels are merely wheels with scoop buckets attached to the radiating spokes, and these scoops scrape the sand from the bottom of the machine and in rising allow the kaolin and water to drain off before the scoop reaches an elevation which will permit of the sand dropping off the scoop.
