Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

2.2.1 Pre-treatment process of Iron Ore Fines In the pre-treatment process, iron ore fines are ground into finer size, suitable for green ball formation. Dry or wet grinding process is adopted for grinding the iron ore fines. In dry grinding process, equipment i.e. drier, ball mill, cyclones/bag filters, hot air generator recirculation fan, air ...

For iron making, the essential feature is the blast furnace, where iron ore is melted (reduced) to produce pig iron. The furnace is charged from the top with iron ore, coke and limestone; hot air, frequently enriched with oxygen, is blown in from the bottom; and the carbon monoxide produced from the coke transforms the iron ore into pig iron ...

Its purpose is to cool the sintered ore to a temperature below 120 °C to allow further processing. As in the sintering process, the material is transported in pallet cars, which this time move in a circle. Cooling fans generate cold air, which is blown into the pallet cars via an air duct to shorten the cooling phase.

Overview: A local steel mill needed a dependable lubrication system for the railcars, conveyor systems, and dumping mechanisms used to move iron ore at their Dearborn Works facility. Dearborn Works is located in southeast Michigan, near Detroit, with carbon steel melting, casting, hot and cold rolling, and finishing operations.

The reasons are as follows: (1) The blades of the analyzer are seriously worn and cannot be classified. (2) The air volume of the fan is not appropriate. Remedy: (1) Change the length of the blade properly. Close the air flow of the small fan. (2) Too fine should increase the imported air volume. Collapse common fault three
