Granulators are machines that form small particles into permanent aggregates to render them into free-flowing state. In Rotating Shape Granulators, the machine shell or the entire mixer shell rotates at a moderate speed around an axis parallel to the ground resulting in the mixing of materials and granulation process.
Particle densification and/or agglomeration is by incorporation of a granulating fluid into the powder mix with low-power-per-unit mass through rotation of the containing vessel and/or intensifier of a cylinder and the rotation speed in rpm(revolution per minute) of the vessel is a function of the vessel size.
Although rotating shape granulators may differ from one another as a result of the vessel geometry and the type of dispersion or intensifier bar, no rotating shape granulator subclasses have been identified. Granulators that fall under this category of granulator are;
These rotating shape granulators have some advantages over each other. For instance, the dead space that may occur in a double-cone mixer granulator is eliminated in the slant double-cone mixer granulator design.
