Title:
GRAVITY FLOW AIR CLASSIFYING MILL
Document Type and Number:
WIPO Patent Application WO2002055202
Kind Code:
A3
Abstract:
The invention relates to a classifying mill with a housing configured for containing a stream of particulate material. A particulate material feed inlet is associated with the housing for introducing the particulate material into the housing. A milling assembly is disposed within the housing and configured for grinding the particulate material into fines and oversize particles. A classifier comprising a classifier rotor is disposed within the housing and below the milling assembly. A fines output at the undersize of the classifier is configured for extracting the fines form the classifier, and an oversize particle collector at the underside of the classifier is configured for extracting the oversize particles from the housing. The classifying mill is arranged such that the particulate milling stream extends downward from the feed inlet (3), through the milling assembly (7), and subsequently through the classifier (12).
