ABSTRACT OF THE DISCLOSURE A rotary drum assembly includes separate agglomerating and hardening drums that are rotated independently of each other. The agglomerating drum has a generally cylindrical configuration with an inner cylindrical wall. A scraper is rotatably position- ed within the agglomerating drum in spaced relation to the inner cylindrical wall with its axis spaced from the axis of the drum. The scraper has a tubular body portion with a plurality of para- llel rows of blades extending radially therefrom. Each of the rows extends lengthwise along substantially the entire length of the scraper body portion and follows a helical path having a single turn about the axis of the tubular body portion. The rows of blades thus make a single convolution about the scraper body portion. Drive means are provided to synchronously rotate the agglomerating drum and scrapper with the scraper arranged to rotate at a preselected and different speed relative to the speed of the drum. Agglomerative material is introduced into the rotating agglomerating drum and forms a layer of agglomerative material on the drum inner cylindrical wall. The scrapper is ro- tated in the same direction as the direction of rotation of the agglomerating drum and at a preselected synchronous speed with the agglomerating drum and at a reselected synchronous speed with the agglomerating drum. The rows of parallel blades on the scraper form a plurality of spaced, elongated, generally longitu- dinal ridges and valleys in the layer of agglomerative material on the drum cylindrical wall. The ridges have a slight arcuate configuration and form less than a single convolution throughout the entire length of the agglomerating drum. The spaced, elon- gated ridges in the layer of agglomerative material extend length- wise in the drum substantially parallel to the axis of the drum and serve as longitudinally extending lifters to mix and agitate other particulate agglomerative materials introduced into the drum by lifting portions of the other particulate agglomerative material from the underside of the bed and depositing the material on the upper surface of the bed. This type of mixing promotes the formation of agglomerates having a preselected, relatively narrow size range. The synchronous rotation of the scraper removes agglomerative material deposited on the surface of the elongated ridges and valleys formed in the layer of agglomerative material so that the desired ridge and valley con- figuration is maintained in the layer of agglomerative material.
