ABSTRACT:
Apparatus particularly for agglomerating particles of different products. A rotatable drum, which has a wall which defines a cylinder and a cylinder void, is mounted on a frame in a horizontal or inclined position. The apparatus includes provision for rotating the cylinder in one direction thereby defining ascending and descending halves of the cylinder. A first part of the cylinder receives particles of a product and has means, such as projecting elements, to rotate the particles for forming a vortex of particles about an axis within the ascending half of the cylinder void such that the axis of the vortex is displaced from and substantially parallel to a central longitudinal axis of the cylinder. The apparatus also includes provision for introducing a product into a second part of the cylinder in the ascending half of the cylinder void, the second part being displaced from the first end of the cylinder and abutting the first part of the cylinder, for distributing secondary product into the vortex of particles within a zone about which the vortex rotates. A spraying device is positioned in the second part of the cylinder void in the descending half of the cylinder for spraying an agglomerating agent onto the particles of the vortex from outside of the vortex.
