第１項または第２項記載の粉砕分級装置。[Scope of Claim for Utility Model Registration] 1. Primary classification is carried out while the pulverized material is air-transported in the crushing section, and then the primary-classified pulverized material is air-flow-transported into a classifier which forms a swirling flow inside to classify the pulverized material. In a crushing and classifying device that performs secondary classification, the main air supply passage for primary classification blows air to the throat part near the crushing part, and the auxiliary air for secondary classification blows air to the housing peripheral wall near the classifier inlet. A pulverizing and classifying device characterized in that the supply passage is provided with an air flow rate adjusting mechanism that can be independently controlled according to the pulverizing capacity of the pulverizing and classifying device. 2. The air flow rate adjustment mechanism includes a flow rate adjustment damper provided in the main air supply passage for primary classification, a flow rate adjustment damper provided in the auxiliary air supply passage for secondary classification, and the crushing capacity of the crushing and classifying device. The pulverizing and classifying apparatus according to claim 1, which is characterized by comprising a control box capable of independently and individually controlling each of the dampers. 3 One or more auxiliary air supply passages for secondary classification shall be provided, and the auxiliary air supply passages for secondary classification shall be branched from the main air supply passage for primary classification, or shall be a passage for supplying combustion exhaust gas. A pulverizing and classifying device according to claim 1 or 2 of the utility model registration claim, characterized in that:
