Abstract
A method of and an apparatus for producing a granular product from an admixture of a powdery material and a liquid binder. The apparatus comprises a casing, a rotor rotatably mounted therein and having a plurality of blades, an annular sleeve movable eccentrically relative to the casing and a plurality of shifters adapted to move the sleeve radially toward and away from the rotor across a spacing or gap circumferentially defined between the sleeve and the blades. The method essentially comprises varying the spacing or gap at selected circumferential areas over predetermined time intervals during operation of the apparatus so as to remove the admixture tending to deposit in the interior of the casing.
