Abstract
Rice or like small objects is milled in a machine comprising a rotating vertical drum having an endless abrasive belt. Chambers are spaced about the drum so that the belt acts as a floor to the chambers with a slight gap in between. The objects are passed vertically downwards and abraded by the belt, surface material removed from the objects passing through the gap and falls out via a subsidiary outlet alongside the main outlet of each chamber.
