Description

Technical Field

[0001] The utility model relates to the technical field of iron ore concentrate grinding, in particular to a multi-stage ball mill crusher for iron ore concentrate. Background Art

[0002] Iron ore concentrate refers to the ore powder produced by crushing, grinding, beneficiation and other processing of iron ore. Iron ore concentrate is the main raw material for pellets. When producing and processing iron ore concentrate, it needs to be crushed, ground, beneficiated and other processing. The fluctuation of iron content will directly affect the quality of the finished pellets. If you want high-purity iron ore concentrate, you need to use ball milling, usually using a ball mill crusher.

[0003] In order to improve the accuracy of iron ore grinding, we have found through search that the patent publication number CN217341634U discloses a high-purity iron ore multi-stage ball mill crusher. The lifting plate can be driven to fall by reversing the lead screw to push the sealing door to fall and insert it into the semicircular rail. After it is fully inserted and aligned with the fixed ring, it can be pressed down continuously, and it can be guided by the guide bar-shaped hole to make the guide column apply accumulated pressure to the sealing door, so that the first sealing gasket presses the second sealing gasket to improve the sealing effect and prevent material leakage. However, after the iron ore concentrate is crushed, when the iron ore concentrate is discharged, the operator is required to open the sealing door manually to discharge the material. However, after the iron ore concentrate is crushed, it is easy for the operator to generate more dust floating. If the operator discharges the material manually, the floating dust is easy to cause certain harm to the operator's body, and it is difficult for the operator to completely discharge the iron ore concentrate in the drum by manual discharge, and it is easy to leave residue in the drum, which is easy to cause certain waste of the iron ore concentrate and reduce the discharge efficiency of the iron ore concentrate.
