Embodiment 1

[0030] This embodiment provides a kind of iron ore pelletizing device, please refer to figure 1 , the device includes:

[0031] Mineral powder bin 2, said mineral powder bin 2 holds said mineral powder 3;

[0032] Specifically, the mineral powder 3 is the raw material of the pellet production line, and the mineral powder warehouse 2 is exactly a container for the raw material mineral powder 3 to achieve the technical effect of feeding the production line.

[0033] A mineral powder belt 1, the mineral powder belt 1 is arranged below the mineral powder bin 2, and the mineral powder 3 falls from the mineral powder bin 2 onto the mineral powder belt 1;

[0034] Specifically, the mineral powder belt 1 is arranged under the mineral powder bin 2, and the mineral powder outlet of the mineral powder bin 2 is facing the mineral powder belt 1, when the mineral powder 3 passes from the mineral powder bin 2 When it falls, it directly falls on the mineral powder belt 1, and the mineral po...

Embodiment 2

[0058] The following is a detailed description of the use method of a kind of iron ore pelletizing device of the present invention, please refer to figure 1 , figure 2 ,details as follows:

[0059] In the embodiment of the present invention, by making two disc pelletizers such as figure 1 As shown, the first pelletizing disk 4 is connected to the upper motor 16 and fixed at a relatively high position through the upper support frame 17, and the second pelletizing disk 11 is connected to the lower motor 18 and fixed at a relatively high position through the lower support frame 19. The bottom of the first pelletizing machine 4, and the upper motor 16 provides power for the first pelletizing disk 4 to drive the first pelletizing disk 4 to rotate, and the lower motor 18 drives the second The pelletizing disk 11 rotates, the upper scraper 6 and the water spray pipe 5 are installed at the upper position of the first pelletizing disk 4, and the mineral powder belt 1 is placed on th...

Abstract

The invention discloses an iron ore pellet balling device. The device comprises an ore powder bin containing ore powder, an ore powder belt arranged below the ore powder bin, a first balling disc connected with the ore powder belt and a second balling disc arranged below the first balling disc. Ore powder falls onto the ore powder belt from the interior of the ore powder bin. Ore powder is conveyed into the first balling disc under the action of the ore powder belt, and green balls with the first weight are generated under the action of the first balling disc. Ore powder, not generating greenballs, in the first balling disc and the green balls with the first weight enter the second balling disc, and green balls with the second weight are generated under the action of the second balling disc. The technical effects that the ore return rate in the pellet balling process is greatly reduced, the yield is increased, the surface quality and strength of the green balls are improved, and energy consumption is reduced are achieved.

Description

technical field [0001] The invention relates to the technical field of pellet production, in particular to a pelletizing device for iron ore pellets. Background technique [0002] The production of iron ore pellets in iron and steel enterprises must first granulate iron ore powder to obtain qualified quality green pellets, and then roast the green pellets 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. At present, the pellet pelletizer mainly used at home and abroad is a disc pelletizer. , adding water and rolling are all carried out in the same pelletizing disk. [0003] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application found that the above-mentioned prior art has at least the following technical problems: [0004] In the prior art, most of the o...
