Kaolin enhances paints' and coatings' appearance, offering increased gloss and sheen control and enamel holdout. Kaolin is also ideal for enhanced whiteness and brightness. For specific paints and coatings, kaolin is also excellent for giving products additional properties like improved corrosion and scrub resistance.

The kaolin underground mining mainly involves digging a series of tunnels underground, which lead directly to the ore body. The main transportation roadway is usually set in the floor 20-40m away from the orebody, and set up a ventilation inclined shaft with a stage height of 25-40m at the edge of the orebody, which can form a diagonal ...

The main technological process of washing kaolin. The sand is first removed by a spiral classifier. It is then entered into a hydrocyclone for classification. The sorted coarse concentrate enters a horizontal spiral centrifugal classifier to separate the paint grade and filler grade kaolin. The raw ore is added with water and dispersant ...

China Clay. (Kaolin) Processing. Kaolin (china clay) is a hydrated aluminum silicate crystalline mineral (kaolinite) formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate like or lamellar particle shape and chemical inertness.
