ABSTRACT OF THE DISCLOSURE A first cylindrical drum member has an inlet portion for receiving a supply of agglomerative materials, such as preheated coal and char. The first drum member has a longitudinal axis and an outlet portion through which the agglomerated product is discharged into the inlet end portion of a second cylindrical drum member. A second drum member is supported for rotation independently of the first drum member in tandem relation therewith and has a longitudinal axis coplanaly aligned with and intersecting the longitudinal axis of the first drum member. A rotary scraper is rotatably positioned within the first drum member in spaced relation to the inner cylindrical wall thereof and has a longitudinal axis spaced from the longitudinal axis of the first drum member, The scraper has a tubular body portion that is rotatably supported adjacent the inlet and outlet portions of the first drum member. A bearing assembly is supported within the first drum member and rotatably supports the rotary scraper rearward end portion adjacent the outlet portion of the first drum member. The rotary scraper has a plurality of rows of blades extending radially therefrom and upon rotation of the scraper are operable to provide a plurality of spaced elongated ridges and valleys in the layer of agglomerative materials that are deposited on the inner wall of the first drum member to aid in the mixing and agglomeration of the agglomerative materials.
