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:
Einecs (european commission no.): 266-007-8
Waste code: 10 02 10
Basel code: b 12 30
Hs code: 2619.00
Fly Ash is by product generated during combustion of coal, and comprises the fine particles that rise with the flue gases. Ash which is collected from the bottom is termed bottom ash. Fly ash is collected by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants and together with bottom ash removed from the bottom of the furnace is in this case jointly known as coal ash. Depending upon the type of coal being used, the specification of Fly Ash varies considerably, but Fly Ash contains substantial amounts of silicon dioxide and calcium oxide (CaO), both being endemic ingredients in many coal-bearing rock strata. We are a reputed Fly Ash Exporter based in India and are supplying Fly Ash different cement, ready mix concrete, steel, refractories and construction industries.
The Major Utilization Areas Of Fly Ash :
- Manufacture of Portland Pozzolanic Cement & Performance improver in Ordinary Portland cement (OPC).
- Part replacement of OPC in cement concrete.
- High volume Fly Ash concrete.
- Roller Compacted Concrete used for dam & pavement construction.
- Manufacture of ash bricks and other building products.
- Construction of road embankments, structural fills, low lying area development.
- As a soil amender in agriculture and wasteland development.
Types of Fly Ash:
- According to the type of coal used fly is classified into two types. Anthracite and bituminous coal produces Fly Ash classified as class F. Class C Fly Ash is produced by burning lignite or sub-bituminous coal. Class C Fly Ash has self-cementing properties.
- Class F and Class C Fly Ash are products of the combustion of coal in large power plants. Fly Ash is collected in electrostatic precipitators or baghouses, and then transferred to large silos for shipment. When needed, Fly Ash is classified by precise particle size requirements, thus assuring a uniform, quality product.
- Class F Fly Ash is available in the largest quantities. Class F is generally low in lime, usually under 15 percent, and contains a greater combination of silica, alumina and iron (greater than 70 percent) than Class C Fly Ash.
- Class C Fly Ash normally comes from coals which may produce an ash with higher lime content generally more than 15 percent often as high as 30 percent. Elevated CaO may give Class C unique self-hardening characteristics.
We have come up as a dependable firm bringing forth Potash Feldspar all over the world. Based in India, we are exporting Potash Feldspar in varied quantity packs. Potash Feldspar are processed and are used for varied industrial applications. Further, we keeping in mind the budget constraints in mind, we offer Potash Feldspar at the market leading prices.
About Feldspar:
Feldspar is non-plastic Potassium or Sodium Alumino silicate mineral represented as KAlSi38or NaAlSi38. Feldspar is used generally for the following purposes :
Ceramic Manufacturing formulations : In making the body composition of several types of ceramics and in preparation of glazes and enamel, Glass Manufacturing and Abrasive Manufacturing.
It is used along with Ball Clay, Kaolin and quartz for tiles and sanitary Wares manufacturing. The presence of iron even in small quantity tends to impart coloration.

Buyers can contact us for availing Bentonite, used for the carrier application of liquid Pesticides and Micro-nutrients. Bentonite Blank Granules are coated with biologically derived ingredients, which are resistant to harmful effects of Ultra-violet radiations of sunlight, become active when they get favorable tropical conditions. Bentonite activate the microbial life within the soil and encourages soil microbes to play an active role. Bentonite loosens light soil enhancing thereby its water retention capacity and increase the efficiency of fertilizer. Bentonite turn saline soil into neutral and helps to increase the dark color of the leaves enhancing thereby Photosynthesis process which ultimately increase the yield of the crops. We, being a reputed Bentonite Exporter ensure standard packaging and systematic delivery of Bentonite.
Applications:
- Bentonite Blank Granules plays very important role in the Pesticides Formulations.
- It acts as carrier for various liquid pesticides and the easiest and safest way of pesticides applications. During application, granules are less subject to drift than in the case with dusting and spray.
We are a reliable industrial source for availing Bleaching Earth . Bleaching Earths have been used in the refinement of edible oils and fats since the end of the 19th century. Naturally-active Bleaching Earth has been used under the name of Fuller’s Earth since about 1880. Bentonite can be transformed into highly active Bleaching Earths by treatment with acid. We source Bleaching Earth from one of the leading producers, with manufacturing capacities in India, Malaysia, and Belgium. They use the unique filter less technology to produce superior and efficient Bleaching Earth for the Edible Oil Industry.
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.
