The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screw-fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (typically approx. 700 °C) and high pressing forces.

The briquetting machine is such a machine that can turn the dust into lime briquette for reuse. Lime briquette machine mainly refers to the roll briquette machine. Put the lime that needs to be briquetted into the briquette machine, and after briquetting, the lime fine and dust can be pressed into various shapes of briquettes.

Hot Briquetted Iron (HBI) is a compacted form of DRI that is manufactured with well-defined, consistent chemical and physical characteristics. HBI is manufactured to be shipped over great distances and melted in a variety of iron and steel processes. It is available throughout the year unlike scrap, which tends to have a collection season.

briquettes. In this process, the iron ore was exposed to heat and hydrogen and carbon monoxide gases to remove oxygen. This transformed the iron ore (with 67 per cent iron content) into metallic granules with over 90 per cent iron content. The granules were then compressed into briquettes about the size and shape of a cake of
