Description

Technical Field

[0001] The invention relates to the technical field of celadon preparation equipment, specifically, to a celadon blank grinding machine. Background Art

[0002] Celadon is a treasure of Chinese ceramic firing technology, a kind of porcelain with green glaze on the surface. The formation of celadon color is mainly due to the presence of a certain amount of iron oxide in the body glaze, which is fired in a reducing flame atmosphere. However, some celadons have impure iron content and insufficient reducing atmosphere, so the color appears yellow or yellowish brown. Celadon is famous for its fine porcelain, bright and smooth lines, dignified and simple shapes, and pure and colorful colors.

[0003] The raw materials need to be purified by various processing methods. Generally, it goes through multiple processes such as selection, washing, crushing, mixing, stirring and iron removal. The specific method of washing is generally to use a slope to build three or four pools from high to low, pour the fine porcelain materials into the pools to turn into mud, and the water slurry flows to the lower pool through different pools. The coarse porcelain materials are precipitated first, and the finest porcelain materials are precipitated in the lowest pool. After the water evaporates, it becomes mud blocks, which is the porcelain mud.

[0004] However, this method of preventing preparation is slow and generally requires a lot of time to wait for precipitation and a lot of time to evaporate water, which leads to slow progress in the preparation of celadon blanks.
