Description

Technical Field

[0001] The present application relates to the technical field of iron ore powder processing, and in particular to an iron ore powder grinding device. Background Art

[0002] Iron ore fines refer to fine iron particles extracted from iron ore by physical or chemical methods. Iron ore is the main ore of iron and contains iron oxides and other mineral impurities. Iron ore fines are usually used as raw materials for the production of iron and steel, and can also be used in other industrial applications.

[0003] When processing iron ore powder, grinding equipment is often required. Existing grinding equipment can usually only perform one grinding process. The particle size of some ground iron ore powder may not meet the standard. If the iron ore powder that does not meet the particle size standard is to be subjected to a secondary grinding process, the iron ore powder must first be taken out, and then screened through a screening device to screen out the iron ore powder that does not meet the particle size standard, and then manually put into the grinding equipment for secondary grinding. This will be time-consuming and labor-intensive, and will affect production efficiency. Therefore, the present application proposes an iron ore powder grinding equipment to solve the above-mentioned technical problems. Utility Model Content
