Enclosures for vertical pulverizer systems are disclosed. The enclosure may include a vertically oriented cylindrical body forming an internal cavity. The enclosure may also include a cover positioned above the cylindrical body. The cover may have a curved surface. Additionally, the enclosure may include an inlet channel formed through the cover, where the inlet channel may be in fluid communication with the internal cavity of the cylindrical body, and an outlet channel formed through the cover, adjacent the inlet channel. Furthermore, the enclosure may include a base component positioned within the internal cavity of the cylindrical body, opposite the cover, the base component having a curved surface, a journal opening formed through the cylindrical body between the cover and the base component, and a journal opening cover coupled to the cylindrical body. The journal opening cover may cover the journal opening.
