Abrégé

Provided is an apparatus for manufacturing hot briquetted iron, the apparatus characterized by comprising: a supply means for cooling and conveying direct reduced iron; a fixed amount discharge means for pulverizing the conveyed direct reduced iron and discharging a fixed amount thereof; a hot briquette forming means for compressing the fixed amount of discharged direct reduced iron at high temperature to form hot briquetted iron; and a cylindrical cooling means for cooling the hot briquetted iron. The cooling means has, inside a cylindrical body, a cooling water spray nozzle and a conveying screw or blade for conveying the hot briquetted iron. The body has, on one side, an inlet through which the hot briquetted iron is introduced and cooling water is discharged, and has, on the other side, an outlet through which the cooled hot briquetted iron is discharged.

Abrégé

The present invention relates to a briquetting device. The briquetting device includes: a pair of briquetting rolls disposed parallel to each other, wherein the pair of briquetting rolls rotate from the outside to the inside so as to compress or deform a raw material; a loading hopper disposed above the space between the briquetting rolls so as to store the raw material; and a plurality of loading screws installed at an incline to, at a predetermined distance from, and along the length of each of the briquetting rolls within the loading hopper to distribute the raw material of the loading hopper between the briquetting rolls. According to the present invention, the raw material may be uniformly distributed on the briquetting rolls and secured by compressive stress. Also, when the briquetting rolls are pressed, the briquetting rolls may have less stress deviation and may withstand high temperatures and severe conditions so as to increase the lifespan of the briquetting device and enable economical management.
