Pellet powder and iron powder

The pelletizing powder manufacturer will introduce the pelletizing powder and iron powder to you.

Mineral powder generally refers to the material powder obtained after crushing the mined ore, such as iron ore powder, which refers to the ore powder with different iron content obtained after grinding, ball milling and magnetic separation of different types of iron ores such as limonite and magnetite. The iron content of ordinary ore powder is 60-68%, and that of super concentrate powder is 70-72%. However, high-grade granular iron powder can be obtained by using reduction method, water or air atomization method, mechanical grinding method, electrolysis method, molten salt decomposition method, evaporation condensation method and other different processes, and the iron content is higher than that of mineral powder, which can meet the use requirements.

Hematite is very common. The main component is iron oxide. Magnetite: the main component is iron oxide. Pyrite: the main component is iron sulfide.

Iron ore powder: natural ore (iron ore) is processed into ore powder through crushing, grinding, beneficiation and other processes.

According to different beneficiation methods, concentrate powder can be divided into magnetic separation, flotation, gravity separation and other concentrate powder.

After the iron concentrate is mixed with binder, pelletizing process is used to prepare pellet with particle size of 10-20 mm, which is dried and calcined at high temperature to solidify the pellet. This ore is called a pellet. The particle size is uniform, the permeability is good and the reducibility is good. But the temperature control of pellet roasting is more strict than sintering. Pelletized ore also requires fine grain size of raw material and low moisture content of ore powder.
