Abstract

The invention concerns a rotating round cooler for the cooling of hot loose material, especially hot iron ore sinter, consisting of a ring-form base plate, which is supported with treadrollers on a circular rail, a holding apparatus fastened to the base plate, a cooling chamber which is fastened movably to the holding device with inner and outer walls permeable to gas, whereby at least the bottom edge of the outer wall is located some distance from the base plate, a horizontal passage to the center of the cooler, a charging apparatus above the cooling chamber, a pick-off above the base plate and in the midst of the cooled material, a drive device for the rotary movement of the cooler, inlet devices for the gaseous cooling medium on the inside of the holding device, as well as blowers for the production of the pressure required for the cooling medium.
