Abstract
A part of an outer wall composing a clean boxbecomes a component of a particle processing apparatus, a processing chamberand the clean boxare integrated, the entire apparatus can be made compact, and in accordance with such compactness, even when a shaft sealing meansand an oil sealing meansare disposed in proximity to each other, reliable shaft sealing performance is secured, whereby a shaft sealing structure enabling processing of fine particles by high speed rotation is provided. Furthermore, integration of setting means for components accompanied with assembly and disassembly of the processing chamber is achieved, the entire assembling structure is simplified and the assembly work is made easier, whereby a particle processing apparatus the assembly and disassembly of which accompanied with cleaning work can be easily carried out in a short time without loss of productive efficiency. Moreover, use requiring a raw material supply unitand use involving no necessity of a raw material supply unitcan be selectively achieved in a balanced manner in accordance with a supply manner for production in view of attachment and detachment accompanied with cleaning work, and this reduces the work burden of attachment, detachment, and cleaning of the supply unititself.
