642,562. Disintegrating-apparatus. BURN, L., TODD, H., and OLIVER, J. April 15, 1948, No. 10506. [Class 59] [Also in Group VI] A granulating machine comprises in combination a cylindrical vertically divided shell 1 with its axis vertical, one side 1a being hingedly mobile and securable to a static side, a depending rotary power shaft 14, driven by an overhead gear 42. mounted axially of said shell, the internal face of said shell being peripherally stepped at 10 in an axial direction to hold removable graduated sieve plates 2, each of said sieve plates resting on a removable support grill 12, said sieve plates being arranged in a series of tiers each in a horizontal plane and adapted to cooperate with a series of granulating arms 4 fast with the axial shaft 2 and adapted to rotate above said series of sieve plates to granulate solid or semi-solid matter from a large particle size to a smaller particle size. The sieve plates 2 and their support grills 12 are divided diametrically into two parts to permit their removal when the side 1a of the shell is opened. One of the granulating arms may be a brush or scraper rather than a smearing arm. A number of granulators may be used in series. According to the Provisional Specification the bars of the support grills may be of downwardly tapering section.
