China Clay: China Clay is a clay mineral with the chemical composition AlSiO3O5(OH)3. It is layered silicate mineral. It is soft earthy, usually white in color, produced by the chemical weathering of Aluminium Silicate mineral like Feldspar. Commercial grades of China Clay are supplied and transported as dry powder form, semi dry noodle form or as slurry. Applications: - It is used in Cer/bamics for body & glazing of Tiles and Sanitary Wares. - In paper it is used as filler. It is also used for paper coating purpose. - It is used in paint also to extend Titanium Dioxide (TiO2) and modify gloss level. - It is used in rubber to enhance reinforcement properties.
China Clay or Kaolin is one of the purest form of clays, composed chiefly of the mineral kaolinite, usually formed when granite is changed by hydrothermal metamorphism. Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5(OH)4. It is a layered silicate mineral, with one tetrahedral sheet of silica (SiO4) linked through oxygen atoms to one octahedral sheet of alumina (AlO6) octahedra. Kaolinite has a low shrink - swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar. In many parts of the world, it is colored pink-orange-red by iron oxide, giving it a distinct rust hue. Lighter concentrations yield white, yellow or light orange colors. Commercial grades of kaolin are supplied and transported as dry powder, semi-dry noodle or as liquid slurry. Salient Features Contributes in improving the chemical resistance, electrical properties and reduction in water absorption Lowers the crack tendency in the finished products Improves shock resistance as well as surface quality
China Clay is a naturally hydrated Aluminum Silicate. It is one of the most abundantly available clay in the Earth's crust. Pure grade of China clay or kaolin clay produced by the processes of levigating. China Clay is also called KAOLIN, it is one of the essential Raw materials for Ceramic Industries, China Clay does not swell on adding water & Alumina present in Clay do not form Isomorphism series with any other metallic compound. Applications: - China clay products are immensely used in the manufacturing of ceramics, papers, paint colors, vitrified tiles, soap, ultramarine and in various other purposes Available Mesh Size : As per requirement Custom sizes and Material of required specifications can be made in case of Bulk and Regular orders.

China clay is characterized by its fine particle size, high brightness and rheology. We develop fine and ultra fine grades of Hydrous Kaolin from our best reserves, for various industries including Paint, Paper, Printing Inks, Paper board, Rubber etc. China clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing Al2O3.2SiO2.2H2O. Kaolin was first discovered in the mountainous province of Kiangsi, China in A.D. 500. The word kaolin derives from the Chinese character kaolin which means high ridge. It was first used by the Chinese to make high quality porcelain.

Ball Clay is a variety of Kaolinite, like china-clay. It differs from china-clay in having high plasticity and less refractoriness. In chemical composition, ball and china clays do not differ greatly except that the former contains a larger proportion of silica. It has derived its name from the practice of removing it in the form of ball-like lumps from the clay pits in the UK. Ball clays are kaolinitic sedimentary clays that commonly consist of 20-80% kaolinite, 10-25% mica, 6-65% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters. Ball clays are relatively scarce deposits due to the combination of geological factors needed for their formation and preservation.

We were the first to start a china clay processing plant in Bhuj-Kutch, Gujarat, by acquiring 100 hectares of land on lease from the government in 1983. Back in 2018, a fully automated kaolin plant was established, featuring High Gradient Magnetic Separation (HGMS) and an automatic filter press that can handle up to 8000 tons every month. In 2020, all plants were revamped to include a ball mill, centrifuge decanter, hydro cyclone, and filter press, which helped us achieve a capacity of 25000 tons per month.
