<p>A crushing apparatus (1) has a gyratory crusher (2), which has an inner shell (6), an outer shell (14) and an eccentric (16). A lubricating system (22) is arranged to conduct a lubricant to at least one movable part, such as said eccentric (16), of the gyratory crusher (2). The lubricating system (22) has an oil sump (24), which collects the lubricant after it has been used for lubrication of the movable part (16), and a valve mechanism (34), which is arranged to apportion a lubricant flow in the crusher (2). The valve mechanism (34) is arranged to assume a first position, in which a first sub-volume of the lubricant flow is conducted directly to the movable part (16) for lubrication of the same and a second sub-volume is conducted directly to the oil sump (24), the second sub-volume constituting 30-100% of the lubricant flow, and a second position, in which at least 90% of the lubricant flow is conducted to the movable part (16) for lubrication of the same.</p> |
