Description

Technical Field

[0001] The utility model relates to a debris remover for iron ore mining, belonging to the technical field of iron ore mining. Background Art

[0002] Iron ore refers to a well or mountain containing rocks or sediments that can be used to extract iron compounds. There are many types of iron minerals. There are about 300 types of iron minerals and iron-containing minerals that have been discovered, of which more than 170 are common. However, under current technological conditions, the ones with industrial utilization value are mainly magnetite, hematite, magma hematite, ilmenite, limonite and siderite.

[0003] In existing iron ore mining, direct transportation of ore by vehicle will carry out a large amount of crushed stone and soil, thereby increasing transportation costs. The iron ore also needs to be sorted, which reduces the convenience of iron ore processing. In addition, during the subsequent impurity removal treatment of the iron ore, a large amount of stone and soil adheres to the outside of the iron ore and is difficult to separate, thereby affecting the impurity removal effect.
