Water Washed Process:

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
