Ball clay is mineral of Kaolinite group; possess the unique property of plasticity when suitably tempered with water. It is extremely rare mineral, founds in very few places around the world. Ball clay forms by the weathering (a mechanical and chemical action of water, wind, glaciers, carbonates, human acid, etc.) of igneous rocks. Ball clays usually contain 20-80% Kaolin and 10-65% Quartz; in addition, there are other minerals, metal oxides and some carbonaceous material present.
Ball clay in Bikaner division is of sedimentary nature and may be classified as secondary clay. The major mineralogical constituent is kaolinite (Al2O3.2SiO2.2H2O) having impurities as fine silica (quartz), hemetite, iron hydrozide, rutile, un-decomposed feldspar, and in some cases lime kankers. The particle size of Bikaner Ball clay is very finer even less than 1 micron with excellent particle size distribution ratio.
Our processing of Ball clay includes proper winning through hydraulic excavators by cutting it in benches, regular lumps size formation and reduction of steals, open drying, hard shorting, quality control and loading backup.
- White Color, High Shrinkage, Highly Plastic
- Highly Plastic, Creamish Color

Types of Available Materials
- Ceramics: The traditional ceramic bodies manly consist of Clay, Quartz and Feldspar. Ball clays have the major role of green strength, working feasibility, and produce a workable, malleable raw material. AceCone is providing ball clay for all major and minor ceramic industries with best suitable properties as per their requirement.
