Mill scale, is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling hot iron or steel billets in rolling or steel mills.
It looks like a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in color.
Being produced during the reheating, conditioning and hot rolling operation for the production of steel articles, the mill scale initially adheres to the steel surface and protects it from atmospheric corrosion, provided no break occurs in this coating.
From the chemical and physical analysis performed on the scrap, and according to the european environmental rules, the material has been classified as a special non dangerous waste, listed in green list
In particular the mill scale can be classified as follows:

About THE Product :
Blast furnace slag is used in the production of cement (iron Portland and blast furnace cement).
Air-cooled blast furnace slag is formed by allowing the molten slag to cool relatively slowly under ambient conditions; final cooling can be accelerated with a water spray. The cooled material is hard and dense, although it can have a vesicular texture with closed pores. After crushing and screening, air-cooled slag can be used in several applications.
Granulated slag is formed by quenching molten slag in water to form sand-sized particles of glass. The disordered structure of this glass gives the material moderate hydraulic cementitious properties when very finely ground into granulated blast furnace slag, but if it can access free lime, the granulated blast furnace slag develops strong hydraulic cementitious properties.
Pelletized or expanded slag is cooled through a water jet, which leads to rapid steam generation and the development of innumerable vesicles within the slag. The vesicular texture reduces the overall density of the slag and allows for good mechanical binding with hydraulic cement paste.
Blast Furance Slag is a nonmetallic co-product which is produced in the process of iron manufacturing, Granulated Blast Furnace Slag is a glassy granular material formed when molten blast furnace slag is rapidly cooled by direct water.
Rapid cooling prohibits the formation of crystals and forms glassy, non-metallic, silicates and alumino silicates of calcium.

Dolomite a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick. They are found all over the world and are quite common in sedimentary rock sequences. These rocks are called appropriately enough dolomitic limestone.
Applications:
- Dolomite is chosen for many construction and building product applications due to its increased hardness and density.
- Asphalt and concrete applications prefer dolomite as filler for its higher strength and hardness.
- Dolomite also finds use in a number of applications as a source of magnesium such as glass and ceramics manufacture, as well as a sintering agent in iron ore
- Palletization and as a flux agent in steel making.
- Farmers use dolomite for agricultural pH control.
- The chemical industry uses the mineral dolomite in making magnesium salts including magnesia, magnesium oxide (MgO), which is used in pharmaceuticals.
PHYSICAL APPEARANCE ASPECT
Agglomerate materials COLOR Gray blackish color
CHEMICAL BEHAVIOR
The basicity of the slag is normally fixed by the amount of lime and calcinated dolomite added, the silicon and aluminum levels of the hot metal and steel scrap charged as well as ferro-alloys.

The power of Zeolite The zeolites are a popular group of minerals known as hydrous aluminum silicate. More than forty naturally occurring zeolites were reported by different research groups and more than 150 zeolites have been synthesized. They have been increasingly used in various application areas such as: - industry - agriculture - waterenvironmental and -protection.
