Abstract:
An apparatus for operating on particulate material, comprising:a housing configured for containing a stream of particulate material; a particulate material feed inlet associated with the housing for introducing the particulate material into the housing; a milling assembly disposed within the housing and configured for grinding the particulate material into fines and coarse particles; a classifier comprising a classifier rotor, disposed within the housing and below the milling assembly, and configured for separating the fines from the coarse particles; a fines output at the underside of the classifier configured for extracting the fines from the classifier; and a coarse particle collector at the underside of the classifier and configured for extracting the coarse particles from the housing; wherein the classifying mill is arranged such that the particulate material stream extends downward from the feed inlet, through the milling assembly, and subsequently through the classifier.
