MLA Group of Industries manufacturers tons of China Clay every year in India. Our modern level China Clay is a flexible item that is utilized widely in the making of paper, rubber, paint, and many other products. Because of our huge manufacturing limits and obtaining of natural substances from petrochemical establishes everywhere, our costs are extremely competitive. Additionally. We are known for leading china clay manufacturers in India and other countries where we export.
MLA Group of Industries is one of the world’s leading manufacturers and suppliers of China Clays, with a moving name in both national and worldwide business sectors. We specialize in the production of China Clays and are exporting in more than 43 countries at present time. We are the leading name in the process of manufacturing China Clays in India.
China Clay, which falls under the Kaolinite group of clays is formed by weathering or hydrothermal alteration of felspathic rocks. It has the general formula Al2,(Si2O5)(OH)4. It is a hydrated alumino-silicate having sheet structure. Free Silica (grit) is the most undesirable impurity and is removed during processing by levigation, sedimentation or air-separation.
High grade china clay deposits are present in West Bengal, Orissa, Rajasthan, M.P. & Gujarat. First we collect the samples from various mines which is analysed for composition and physical and chemical properties and its suitability for various applications is then studied. Moreover, sustained availability of the material with no variation from mines is given utmost importance to ensure consistency in final product.
The raw china clay is subject to a refining process including spiral classification, hydrocycloning, deflocculation, bleaching and finally drying, micronizing, air-classification and surface treatment. Our processing ensures consistent composition, control of top-cut and average particle size and freedom from free silica.
Our quality assurance system extends from mining to micronizing to ensure near-Zero-defect products :-
