Size Reduction Grinding

Feb 11, 2018 New milling, grinding and size-reduction equipment helps processors obtain better efficiencies and develop new products. Although milling and size-reduction equipment may be mature — some technologies date back to the 1800s — evolving needs of chemical processors, including the demand for better efficiency, new applications and materials and other trends, require milling and size-reduction

    Grinding and cutting reduce the size of solid materials by mechanical action, dividing them into smaller particles. Perhaps the most extensive application of grinding in the food industry is in the milling of grains to make flour, but it is used in many other processes, such as in the grinding of corn for manufacture of corn starch, the grinding of sugar and the milling of dried foods, such as
