Description
Class B02 covers mechanical processes for reducing solid materials to smaller particles through crushing, pulverising, or disintegrating, as well as preparatory operations for grain processing before milling. This class encompasses equipment, machinery, and methods for breaking down materials such as minerals, ores, coal, stone, and agricultural products into finer forms. It includes both the crushing apparatus itself and associated preparatory treatments, particularly the cleaning, conditioning, and sizing of grain prior to flour or meal production.
IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
