FLINT CHERT CHALCEDONY


Flint (or flintstone ,chert ,chalcedony) is a hard, sedimentary cryptocrystalline form of the mineral quartz, categorized as a variety of chert. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones. Inside the nodule, flint is usually dark grey, black, green, white, or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. From a petrological point of view, "flint" refers specifically to the form of chert which occurs in chalk or marly limestone. Similarly, "common chert" (sometimes referred to simply as "chert") occurs in limestone.

Flint pebbles are used as the media in ball mills to grind glazes and other raw materials for the ceramics industry. The pebbles are hand-selected based on colour; those having a tint of red (indicates iron content) are discarded. The remaining blue-grey stones have a low content of chromophoric oxides and so impart lesser amounts of colouring contaminants.

In the UK, flint pebbles were traditionally an important raw material for clay-based ceramic bodies. After calcination to remove organic impurities and induce certain physical reactions, and milling to fine particle size, flint was added as a filler to pottery bodies. However, flint is no longer used and has been replaced by quartz as is used in other countries. Because of this historical use, the word "flint" is used by US potters to refer to siliceous materials which are not flint.

As the flint chert is kind of hard stone, Zenith recommand the hydraulic cone crusher. The cone crusher is suitable for crushing hard stones because of its structure and material.

The processing line of flint cosists of jaw crusher,cone crusher etc. Jaw crusher is used as the primary crusher and it's the most widely used crusher. The two jaw plates can crush the stones as quartz mineral forcefully. Then the cone crusher crush the mineral further.HP cone crusher is equiped with a high pressure hydralic system, the operation is easy and safe. It's suitable for hard stones.

Zenith produce kinds of crushers and grinders. And the equipments are exported to more than 100 countries and regions for mining minerals and ores. The production technology of Zenith is in the leading position in the mining industrial in the world. Compared with Sandvik and Mesto, we are in small scale but our technology are advaned. And as the acception of the suggestions and advices from clients, our products are better and better. Since now the products are well recieved all over the world.
