What is Iron Ore


Iron ore is an important industrial source, a kind of iron oxide ore, an economically available mineral aggregate containing iron element or iron compound, and there are many kinds of iron ore. Among them, iron-making products mainly include magnetite, siderite, hematite and so on. Iron exists in nature in the form of compounds, and natural iron ore can be gradually selected after crushing, grinding, magnetic separation, flotation and gravity separation. Therefore, iron ore is an important raw material in the field of steel production, iron ore with a general grade of less than 50% needs to be processed before smelting and utilization.

The use of iron ore

The main field of application of iron ore is the steel industry. Recently, steel products are widely used in the national economy and in people's daily lives. They are the basic materials necessary for social production and life. Steel is a very important structural material in the country. It occupies a very important place in the economy and has become an important pillar of social development. As the basic raw material of the steel industry, iron is an important raw material that underpins the entire steel industry. Iron ore plays a fundamental role in the steel industry. It can be cast into pig iron, wrought iron, ferroalloys, carbon steel, alloy steel, special steel, etc., pure magnetic iron ore can also be used as a catalyst for ammonia synthesis.

The composition of iron ore raw materials

SideriteMain ingredient is FeCO3

Iron Ore Powder Making Equipment Selection Program

Fineness100-200 mesh
ModelVertical mill or Raymond mill

Stage 1: Crushing of raw materials

The material is crushed by the crusher to the fineness that can enter the mill(15mm-50mm).

Stage 2: Grinding

The crushed small pieces of material are sent to the storage hopper through the elevator,and then sent to the grinding chamber of the mill evenly and quantitatively through the feeder for grinding.

Stage 3:Classification

Through classification, the coarse powder will return to main mill to grind again.

Stage 4:Collection of finished products

The powder that meets the fineness enters the dust collector through the pipeline with the air flow for separation and collection, and the collected finished powder is sent to the finished product silo by the conveying device through the discharge port, and then is packaged uniformly.
