Particle technology affects the entire human population. It is involved in the manufacture of agriculture chemicals, asphalt, paint, and pharmaceuticals, just to name a few. The size and shape of the particles play an important role in the manufacturing processes. A change in size or shape can change the product produced. Experiments were run to test the effects of agitation rate, magma density, and residence time on adipic acid and sodium chloride crystals. Experiments were executed in a one-liter, double-jacketed, stirred vessel. Digital images of the broken crystals were taken with a microscope/digital camera combo. ImagePro Plus was used to analyze the size of the broken crystals. The greatest change was seen between the two magma densities. It can be determined that change in size and shape based on the variables does exist. A specific set of variables should be introduced for each process in industry to achieve the desired results.
