Mar 09, 2013· Fig 2 Material flow in a sinter plant The flexibility of the sintering process permits conversion of a variety of materials, including iron ore fines, captured dusts, ore concentrates, and other iron-bearing materials of small particle size (e.g., mill scale) into a clinker-like agglomerate.
The sinter mix, besides the ore fines, usually contains other materials like flue dust, return fines, limestone and/or dolomite etc., in order to control the properties of the product as well as to utilize industrial waste. Return sinter fines having lower fusion temperature than the raw mix serve as seeds for initiation of the sintering process.

Apart from these wastes large quantity of iron ore fines are generated during mining, crushing and grinding. Most of them are in fine fraction and difficult to use even for making sinter use as a feed material for the blast furnace. Now a day's pelletization is getting popular which uses iron ore fine and becomes a feed material after induration.
No one shall, at any time, throw away any lighted tobacco, cigars, cigarettes, matches or other lighted material, on any forestland, private road, public highway or railroad right of way within this state.

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical ...
Jul 07, 2017· The physical properties of the samples of iron ore fines were monitored during the scale model test, and the point at which moisture migration began to occur was determined. The boundary where the material showed a significant loss of shear strength, referred to as the critical failure curve, was also determined using the iron ore fines plunger.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.
Iron ore lumps: size 10-40mm Iron ore fines: Granular size of up to 10 mm for up to 90% of the cargo. While lumps are crushed to 5-20mm size in crusher, normally 30% fines (waste) will be generated.
