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.

Kaolin uses are multiple and diverse. Kaolin are used as functional filler, extender, ceramic raw material and pigment because of its whiteness and fine particle size. Kaolin also hold importance as raw material in refractory applications, concrete, rubber and fiber glass manufacturing. We, as a Kaolin Exporter welcome any size of international orders from Middle East and other countries.
Applications:
Paper:
Kaolin used as a coating pigment and as a filler to replace fiber. It possesses desirable optical properties.
Concrete:
Kaolin helps to improve strength and durability of concrete. When added to concrete mix, reacts with free lime released during cement hydration to produce additional cementitious material, resulting in an improved high performance concrete.
Plastics :
Kaolin is widely used as filler in the plastics industry because of its inert chemical nature and its unique size, shape and structure.
Agriculture :
It is used as a carrier and diluent in fertilizers, pesticides and related products. It is suitable as carrier because it aides the retention of the formulations on the plant.
Rubber :
It is commonly used as functional filler in rubber applications. While Kaolin improves overall performance for Rubber in general, different types of white pigment play specific roles in rubber application.
Paint :
Kaolin used as an extender in paints. It reduces the amount of expensive pigment such as Titanium Dioxide. It assists with desirable rheological properties that help maintain proper dispersion and provide bulk to the product.
Ceramic :
Kaolin improves whiteness and brightness of ceramic body. Good plasticity, good shrinkage, low water absorption and casting rate are also very important properties of kaolin.
Micro silica also known as fume, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 mm. The main field of application is as pozzolanic for high performance concrete because of its extreme fineness and high silica.
Applications :
Silica is added to Portland cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste.
Advantages :
Addition of silica also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.
Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application.
We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices.
Applications of Calcined Bauxite:
Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%.
Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement.
