Diatomaceous earth also known as diatomite or kieselgur, is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white to off-white powder. It has a particle size ranging from less than 1 micron to more than 1 millimeter, but typically 10 to 200 microns. This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity. The typical chemical composition of oven dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide. Diatomite is a siliceous rock, mainly distributed in China, the United States, Denmark, France, Russia, Romania and other countries.

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide, as an absorbent for liquids, as cat litter, as an activator in blood clotting studies, and as a component of dynamite. As it is also heat-resistant, it can be used as a thermal insulator.

Diatomaceous earth is used in industry as insulating material, filter material, filler, abrasive materials, sodium silicate material, bleaching agent and catalyst carrier.

Diatomaceous earth grinding mill or Diatomite grinder mill
Grinding mill of diatomaceous earth or diatomite is applied widely in paints and coatings industry. Therefore, the use of diatomaceous earth more and more widely distributed, diatomaceous earth is also used to adjust the indoor humidity, to eliminate smell and function of the room clean and disinfection, many of diatomaceous earth as raw material to the new indoor and outdoor paint, decoration materials at home and abroad more and more consumers. Materials, industrial development brought about the extensive application of powder, processed by the grinding mill can be applied to more areas of diatomite can be said that modern industry and cutting-edge science and technology and people's lives indispensable materials, especially paint industry is indispensable.
