Step 2Blunging

Blunging

Raw China clay (Kaolin) is mixed with water to create milk-shake-like slurry. Slurry is simply the water and dispersed clay mixture, which puts the clay particles in suspension.

Step 3De – Gritting

De – Gritting

The dispersed China clay (Kaolin) slurry is usually transported through pipelines to degritting facilities, where coarse impurities (such as quartz, sand, muscovite mica, and heavy minerals) are removed from the dispersed kaolin slurry with the help of gravity.

Step 4Solid-Liquid Separation

Solid-Liquid Separation

Here 35-40% solid concentration slurry is fed in to the filter press by stroke pumps to separate water from dispersed China clay (Kaolin) slurry. Here due to stickiness of the clay pressure is maintaining up to 8 kg/cm2.After formation of clay cake the moisture content varies from 23-25%.

Step 5Filtering and Brightness enhancement

Filtering and Brightness enhancement

With both the fine and coarse China clay (Kaolin) particle fractions, brightness is enhanced through one or more processes which will remove iron, titanium, organic, and other undesirable elements.

Step 6Draying

Draying

Wet cake of China clay (Kaolin) having 23-25 % moisture is dried with the help of natural resource. Generally sunlight & wind are used for the same. Here moisture of dried China clay (Kaolin) cake is maintained 5-6 %.

Step 7Powdering and Packing

Powdering and Packing
