We offer fully Calcined kaolin( China Clay ) which is a thermally structured aluminum silicate, produced by heating natural kaolin at a very high temperature. The calcination process changes the shape of kaolin particles and increases its hardness.
While kaolin clay is widely used in its raw form, heat treating kaolin to produce metakaolin and other forms of calcined kaolin further increases its usability and creates an engineered product. Calcination can enhance or alter a variety of the mineral’s properties to produce a material with characteristics suited to a given application. This might include improving the hydrophobicity and abrasiveness of the material, or even enhancing optical or electrical characteristics.
Calcination causes to kaolin after going under several reactions. Between 100°–150°C, free moisture is off. After free moisture is removed, chemically bound moisture is driven off in a process known as dehydroxylation. It forms a product known as metakaolin and typically happens between 400° – 600°C. Beyond dehydroxylation, exothermic re-crystallization causes the metakaolin to transform to the spinel phase. Then crystals of mullite begins to form from the spinels at temperatures beyond 1050°C. If the temperature is allowed to exceed ≤1400°C, then cristobalite will form. This Kaolin calcination is carried out in a rotary kiln, often referred to as a calciner.
After formation of cristobalite, it is being sent to Vibratory Screener system. This method of particle separation uses gravity, motion and mesh screens or sieves to accomplish the separation. The screener is mechanically gets vibrated in a controlled manner to allow the particles to flow across the screen and outward in a spiral pattern. The smaller particles fall through the mesh screen and continue to spiral until they are discharged.

Combining limestone, supplementary cementitious products, we established the most effective product with low CO2 emission to combat greenhouse gas. The calcined graded clay is highly effective that we have at a substitution levels. Calcined clay is added up with multiple range of metakaolin which derive as low-grade calcined clay (LGCC), and high-grade calcined clay (HGCC).
In India, Calcined clay and Calcined clay graded is used in multiple industries. Bioth of the products includes the cement, ceramic industry to form products from the main material. In painting, paper coating, fiber glass extender, calcined clay is used. In fact in pharmaceuticals, textiles, rubber, plastic manufacturing, our products are being used.
The primary products comes after the reactions are, calcined fire clay grains. There has some specific size range comes up like, calcined fire clay dust ( 0-1 mm ), calcined fire clay grain ( 1-3 mm ), calcined fire clay grain ( 3-5 mm ).
In order to maintain the quality, Fe2O3 has to be ≥1.5%, Al2O3 at ≤42.0% range,, Apparent Porosity at ≥5.0%, and Bulk Density at 2.42gm/cc.
