Granules are particles with a more or less spherical shape. The diameter of these particles can be between 2-30 mm. Granulation is widely used in other fields of technology, if spherical particles are needed. The principle of the shaping method is best described by the snowball effect. A round dish (see Fig. 8.10) is used, which is rotating about an inclined axis, the angle of inclination of which is variable. Small particles are fed into the dish. At the same time a cohesive slurry...
