Blunging

The 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.

De-gritting

The slurried China Clay (kaolin) is usually transported through pipelines to degritting facilities, where sand, mica and other impurities are extracted with the help of gravity.

Solid-Liquid Separation

We feed 35-40% solid concentration slurry in to the filter press by stroke pumps to separate water out of slurry. Due to stickiness of the clay we go up to 8 kg/cm2 pressure. After formation of clay cake the moisture content varies from 20-25%.

Filtering and Brightness enhancement

With both the fine and coarse China Clay (kaolin) particle fractions, brightness is enhanced through one or move processes which will remove iron, titanium, organic, and other undesirable materials.

Drying

Large rotary vacuum filters remove water from the slurried China Clay (kaolin). Drying is effected through solar power.

Powdering and Packing

After Sun drying we break the cakes in to small sizes max 5” or powder as per the requirement of customer.

We make powder by hammer grinding mill.
