The morphology of suspended crystals of K-alum in a crystallizer was investigated by microscopic observation. These crystals were broken, and their form and surface conditions were changing continuously. When a crystal suspended in the crystallizer was constantly colliding with an impeller, the crystal weight W decreased with elapsed time θ. This change in crystal weight was expressed as W = W0 exp (-K. θ), where W0 was the initial crystal weight and K was a rate parameter which was determined experimentally and was considered to be a function of collision energy and collision frequency, etc. In the case of suspended crystals, where the crystal weight decreased with elapsed time θ, its change was also expressed by the above equation.
