Apparatus for producing hot briquetted iron

An apparatus for producing hot briquetted iron (HBI), the apparatus comprising:

• a feeder unit configured to cool and transport direct reduced iron (DRI);
• a quantitative dispenser unit configured to pulverize the DRI and discharge a predetermined fixed amount of the pulverized DRI at a time;
• a hot briquette forming unit configured to hot-pressing the fixed amount of the DRI to form hot iron briquettes;
• and
• a cooler unit configured to cool the hot iron briquettes,
• wherein cooler unit comprises a cylindrical body with an inlet provided on a first side thereof and an outlet provided on a second side thereof, a cooling water spray nozzle provided inside the cylindrical body, and a transport screw or blade configured to transport the hot iron briquettes from the inlet to the outlet and provided in the cylindrical body, wherein the hot iron briquettes are introduced into the cooler unit through the inlet and are discharged from the cooler unit through the outlet, and cooling water retained in the body of the cooler unit is discharged outside through the inlet.
