Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...

Grinding also increases the total surface area of a given weight of feed, thereby allowing more space for steam condensation during the conditioning process. This results in a higher feed temperature and more water absorption which together, within the time available, increases gelatinization of raw starch.
