A mixer (10) for mixing molten metal in a kettle is disclosed. The mixer (10) broadly includes a housing (12), a drive train assembly (14) supported on the housing (12), and an impeller assembly (16) rotatably coupled to the drive train assembly (14). The drive train assembly (14) broadly includes a power source (18), a rotatable shaft (20), and a transmission (22) drivingly connecting the power source (18) and the shaft (20). The housing (12) is a self-contained unit that supports the mixer (10) and includes an upper housing section (24) that is shiftable relative to a lower housing section (26) between a raised position and a lowered positioned. The transmission (22) includes an endless belt (118) than entrains a fan (122) fixed to the shaft (20). The fan (122) forces a stream of air over bearings (106,108) that support the shaft (20) and over the power source (18) when the shaft (20) is rotated.
