Refractory Clay

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.

Calcined Clay or Refractory clay is obtained by Calcining (heating) superior-grade Clay at high temperatures (from 850o C to 1600o C).

This removes moisture and volatiles which thereby increases the Alumina content.

Compared to an Alumina content of about 30% to 40% in raw Clay, Calcined Clay has an Alumina content of 40% to 60%.

The Calcination is carried out in Rotary Kilns at different temperatures ranging from 850o C to 1600o C depending upon the customer's application.

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.
