AGGLOMERATING PROCESS AND APPARATUS Abstract of the Disclosure The invention is directed to agglomerating apparatus in the form of a rotating drum and a method for agglomerating and controlling the size of carbonaceous material, such as particulate coal, finely divided char and, optionally, a binder such as pitch. Control of the agglomerate size dis- tribusion discharged from the drum is achieved by increasing the relative residence time of the small or growing agglomerates and by limiting contact between the large formed agglomerates and the small forming or growing agglomerates. The preferred means to insure adequate growth time for the small agglomerates consists of a plurality of annular ribs spaced about the inside wall of the drum and a cooperative scraping mechanism. The scraping mechanism comprises a plurality of scraper blades projecting radially from a rotating shaft throughout the length thereof of the agglomerate-forming section of the drum. However, at the annular paths wherein a rib is found the scraping blades are shorter in length. -1-
