A breaker for hot material which includes a main shaft mounted for rotation about its longitudinal axis. A plurality of spaced apart discs each having a plurality of circumferentially spaced passages therethrough are mounted on the main shaft. A sleeve interconnects the spaced apart discs to define a plurality of passages along the length of the breaker. A plurality of circumferentially spaced hammers are mounted on the breaker externally of the sleeve. Cooling fluid such as air is supplied to each of the passages. Openings in the sleeve discharge cooling fluid from the passages to the area of the hammers. The main shaft is mounted in bearings and a fan arrangements cools these bearings.
