A granulator uses either a wet process or a dry process to bind small particles, such as powders, into larger particles. When used for tableting or coating, granules allow greater compressibility of a powdered material, and reduce or eliminate the dust that comes from working with powder. Granulating a powder before adding it to a mixture allows it to incorporate into a mix more evenly. When powder particles are too fine or dense, they can separate from the other components of a mixture.
