Description

Technical Field

[0001] The utility model relates to the technical field of ore pellets, in particular to an online monitoring device for iron ore pellet forming. Background Art

[0002] The production of iron ore pellets in steel enterprises must first granulate the iron ore powder to obtain green balls of qualified quality, and then roast the green balls at high temperature to obtain finished pellets. There are two types of iron ore powder granulation equipment, one is a disc pelletizer and the other is a cylinder pelletizer. The disc pelletizer is currently the main pelletizer used at home and abroad. Generally, the addition of ore powder, water addition and rolling growth are all carried out on the same pelletizing disc.

[0003] The existing Chinese patent with the announcement number CN107794366B discloses an iron ore pelletizing device, the key points of its technical solution are: the device includes: a mineral powder bin, the mineral powder bin contains the mineral powder; a mineral powder belt, the mineral powder belt is arranged below the mineral powder bin, the mineral powder falls from the mineral powder bin to the mineral powder belt; a first pelletizing disk, the first pelletizing disk is connected to the mineral powder belt, the mineral powder is transported to the first pelletizing disk under the action of the mineral powder belt, and the first amount of raw balls is generated under the action of the first pelletizing disk; a second pelletizing disk, the second pelletizing disk is arranged below the first pelletizing disk, and the mineral powder that has not formed raw balls in the first pelletizing disk and the first amount of raw balls enter the second pelletizing disk; and the second amount of raw balls is generated under the action of the second pelletizing disk. The technical effect of greatly reducing the return rate of the pelletizing process, increasing the output, improving the surface quality and strength of the raw balls, and reducing energy consumption is achieved.
