Not illustrated. 1904 Excerpt: ...and settle at the bottom of the tube at b, while the lighter and smaller grains will be carried upwards and discharged with the water. And for each rate of flow there will be a corresponding set of grains which will just fall. Similarly, if battery pulp can be sent in an upward stream at a certain velocity through a pipe, some of the grains will be left behind and some carried forward by the ascending current. In a tube such as that shown in fig. 39, for instance, the heavy coarse sand will fall back and collect at b in the bend. Such an apparatus would, however, soon choke itself, but fig. 40 shows a continuous arrangement in which there is a small outlet for coarse sand at the bottom of the bend. Naturally, some fine stuff and turbid water will flow out with the sand if no means be provided to prevent this. But by forcing in a small stream of clear water through pipe c, the downward pressure of the slimy water is overbalanced and the coarse sand escapes alone in the clear water by pipe d. By regulating the size of the openings b, c, and d, and varying the height of the discharge e, a clean product can be obtained, the nature of which, however, depends essentially upon the velocity of flow in the main tube. Therefore, by repeating the operation with a series of decreasing velocities, several grades of sorted material can be obtained. Mixed grains can also be sorted by means of a horizontally flowing stream of water, for, by sufficiently reducing its velocity, it will be unable to carry forward the largest and heaviest particles, which will consequently sink to the bottom. A further reduction of velocity will cause other finer grains to sink, Fio. 39.--Action of the Spitzlutte. until finally nothing but water flows away. This is the principle of the spitzka...
