FIELD: metallurgy.
SUBSTANCE: cooler contains grating for reception and maintaining of hot bulk material supplied from industrial roasting furnace, cooling gas channel joined with gaps in grating for introduction of cooling gases to hot material, and compressed air system for blowing of compressed air to hot material on grating. Cooler is provided with flow restriction device installed in cooling gas channel. Flow restriction device is designed as plates or disks installed in cooling gas channel across it or at an angle to it.
EFFECT: stability of cooler operation due to prevention of compressed air passing through cooling gas channel.
