Abstract
A mill offers superior milling efficiency by being provided with a partition to divide a milling chamber into a first guide path and a second guide path. Particles of a milling material that have been ground at a milling area in the milling chamber are guided into a particle classifier through the first guide path, and the ground particles of the milling material that were classified by the particle classifier as requiring further milling are guided back into the milling area through the second guide path.
