<p>A pulverizer auxiliary lubrication system (12) particularly suited for use with a pulverizer bowl mill (10) of the type that is operative for effecting the grinding of material. The subject auxiliary lubrication system (12) is designed to be employed to supplement the pulverizer bowl mill's (10) existing lubrication system (48) whereby the beneficial features of the latter are retained while the disadvantages thereof are eliminated. To this end, the subject auxiliary lubrication system (12) includes an oil pump (72), an electric motor (74) coupled (76) to and operative for driving the oil pump (72), one or more filters (78), a pressure relief valve (80), connecting piping (82, 84, 86, 88), gauges (68, 94, 96) and controls (90, 92, 98, 100, 110), and means to supply oil to (86, 88) and draw oil from (82, 84) the pulverizer bowl mill (10). The benefits to be derived from the employment of the subject auxiliary lubrication system (12) are, among others, that the lubricating oil is filtered to remove contaminants which have a deleterious impact on bearing (56, 70) and gear (52) operating life; the flow of oil to the upper shaft bearing (56) of the pulverizer bowl mill (10) is higher than that attainable with the existing integral pump (58) of prior art forms of pulverizer bowl mill lubrication systems such that this higher flow promotes better cooling of the upper bearing (56) to prolong its operating life; and the forced flow of oil through the lower shaft bearing (70) assembly provides a purging effect to prevent accumulation of contaminants in this area.</p> |
