Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, specifically to a dust removal device for primary crushing of iron ore. Background Technology

[0002] Iron ore is an important mineral raw material mainly used for smelting iron and steel. Its main component is iron oxide. The mining and processing of iron ore is an important part of the metallurgical industry. After mining, iron ore needs to be primary crushed by a jaw crusher, then fed into a cone crusher for medium and fine crushing, and finally fine crushing or grinding as needed. A large amount of dust is generated during the primary crushing process of iron ore. The dust released into the air reduces air quality and causes environmental pollution. Secondly, the friction and collision between the crushed iron ore pieces during transportation also generate dust. Dust may cause wear and tear on production equipment, increasing the cost of maintenance and replacement parts. To address the above problems, the inventor proposes an iron ore primary crushing dust removal device to solve these issues. Utility Model Content
