Zusammenfassung: | To provide a powder processing device that prevents temperatures of a shaft and bearings from rising and can stably be operated for a long period of time.SOLUTION: A powder processing device A comprises: a housing 10; a shaft 20 on which a powder processing unit 40 is mounted, the powder processing unit rotatable centering a center axis Cx and rotating around the center shaft Cx in an inner space 100 of the housing 10 to process the powder; bearings Br1, Br2 which support the shaft 20 rotatably with respect to the housing 10; and a cooler 50 which cools the shaft 20 and the bearings Br1, Br2. The cooler 50 has a cooling medium pipe 51 which extends along the shaft 20 and through which the cooling medium flows.SELECTED DRAWING: Figure 1
【課題】シャフト及び軸受の温度上昇を抑制し、長期間安定して動作可能な粉体処理装置を提供する。【解決手段】粉体処理装置Aであって、筐体10と、中心軸Cxを中心に回転可能であるとともに筐体10の内部空間100において中心軸Cx周りに回転して粉体を処理する粉体処理部40が取り付けられるシャフト部20と、シャフト部20を筐体10に対して回転可能に支持する軸受Br1、Br2と、シャフト部20及び軸受Br1、Br2を冷却する冷却部50と、を有する。冷却部50は、シャフト部20に沿って延びるとともに冷媒が流動する冷媒配管51を有する。【選択図】図1 |
