Kaolin Stone Processing

In the kaolin mining process, crushing is the first step. Using the crushing plant, we get kaolin particle, then using the grinding plant with one type of kaolin mill, we get kaolin powder.
"SBM will provide you with complete kaolin crushing grinding plant including stationary and portable plant."

Kaolin is a clay mineral It is a stacked up silicate layer with one tetrahedral sheet linked through oxygen to a single octahedral sheet of Alumina. Rocks that are prosperous in Kaolin contents are normally termed as china clay or kaolin.

Kaolin clay is formed from the weathering of silica rich rocks such as granite and gneiss, it occurs with feldspar and quartz. The clay is separated from the other constituents by washing with water cannons and the slurry is then centrifuged to remove 75% of the minus 0.002mm fraction.

Clay is also processed to remove any contaminating materials such as iron, aluminium quartz and feldspar. It is dried and fired to produce molochite and then fed into a ball mill. Various product gradations can be produced.

Kaolin Crushing Machine

Crushing kaolin is of great importance and necessary in the world. Kaolin crushing in mining is developing more and more and so kaolin crusher plays a more and more important role in kaolin mining.

Output of the un-coal department of natural kaolin, according to their quality, plasticity, and sand content, can be divided into three types that is hard, soft and sandy kaolin in industry. The Focused place of mining kaolin around the world is the United States, Britain, Brazil, the Czech Republic and so on.

As the rapid development kaolin mining industry in Brazil, the international Three Kingdoms including the United States, Britain, Brazil has formed. They are not only large countries of refined kaolin quarry producing, but also a major exporter.

Our crusher also does well in areas like metallurgy, building materials, chemicals, mining minerals in areas such as grinding materials processing.

Kaolin Grinding Plant

The kaolin particle is not the finished products, what we need is kaolin powder. Usually the powder is 100-800 mesh, 1250 mesh, and 4000 mesh. In order to get them, we need use kaolin mill to grind kaolin particle into powder.

Ball mill for kaolin is the common grinding mill in kaolin production line, it is used for coarse grinding, the finished size is 0.074-0.4 mm, the capacity is larger than other kaolin grinding mill.

The Raymond mill is the traditonal Grinding mill and porpular around the world. It finish particles have a good uniformity of finess, with passing screen rate as high as 98%.

MTM Trapezium grinding mill is used as substitute of raymond mill for grinding Kaolin. It is lower consumption, lower investment, more environment friendly, smaller occupation area.

What's more, there are lots of other grinding mills for kaolin grinding. For more info, you can chat with our engineers online.
