What is pellet induration?
The induration process for green pellets involves 4 main stages: (1) drying, (2) preheating, (3) heating and (4) cooling. In the drying stage (105–260°C), water is removed from the pellet in a controlled process to avoid cracking.
What are iron ore pellets?
Pellets are small balls of iron ore used in the production of steel. They are made with technology that uses the powder that is generated during the ore extraction process, once considered waste.
What is the density of iron pellet?

How do you Pelletize biomass?
To make pellets, the biomass must first be cleaned to remove contaminants. The clean biomass is then ground in a hammer mill or chipped to a uniform size, which must be less than the thickness of the pellet that will be produced. Grinding down biomass helps to reduce the horsepower the pellet mill must produce.
What are the four types of iron ore?
There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.
What is iron ore density?
The results of the bulk density determined in the field for iron ore shown are 2.98 to 3.03. The average bulk density for float ore can be taken as 2.51. In the case of Iron ore the average works out to be 2.88.
How do you make iron ore pellets?
Supplier of both Straight Grate and Grate Kiln pellet plants Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.
What does a sinter plant do?
The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier.
What is biomass pallet?
Biomass pellet is one kind of biofuel resources. Biofuel or biomass energy, refers to renewable energy sources such as solar energy,wind energy,etc which can both generate heat or electricity for human life and produce little damage to the environment at the same time.
