A. The ring die pellet mills were designed at around the 1930's based on the design of ring die. The basic pelleting principle of the ring die pellet mill is a simple operation where feed mass is distributed over the inner surface of a rotating, perforated die ahead of each roll, which compress the feed mass and compress it into the die holes to form pellets.

Currently, because of the increasing processing requirements, superfine grinding methods, such as ball milling, jet milling, and highpressure expansion, have begun to be applied in the food industry. Tan et al. (2015) reported that waxy and highamylose corn starches had a lower viscosity and better pasting stability via planetary ballmilling.
