International Classification:

B02C 1504

US Classification:

2411012

Abstract:

A journal bearing system (50, 52) particularly suited for use in a bowl mill (10) of the type that is employed for purposes of effecting therewithin the pulverization of material such as coal. The function of the subject journal bearing system (50, 52) is to provide the bearing support for the journal shaft (22, 54) on which the pulverizer roll (20) is mounted that through the coaction thereof with a suitable surface (14) provided for this purpose effects the pulverization of material. The subject journal bearing system (50, 52) includes first bearing means (62, 116) positioned at a first location along the length of the journal shaft (22, 54) so as to be cooperatively associated therewith, second bearing means (80, 128) positioned at a second location along the length of the journal shaft (22, 54) so as to be cooperatively associated therewith, oil seal wear ring means (86, 140) positioned at a third location along the length of the journal shaft (22, 54) so as to be cooperatively associated therewith and air seal ring means (88, 142) cooperatively associated with the upper journal housing (58, 110) and operative for purposes of effecting control over seal air pressure.
