Description

Technical Field

[0001] The invention relates to the technical field of attapulgite processing, and in particular to a attapulgite modification device and method. Background Art

[0002] Attapulgite, also known as palygorskite, is a natural one-dimensional nano-type clay mineral composed of hydrated magnesium aluminum silicate. Due to its unique natural structure, attapulgite is easy to agglomerate with itself or other impurities, resulting in a reduction in surface area and closed pore structure, which interferes with its adsorption and decolorization performance. Therefore, the adsorption effect of untreated attapulgite ore is not ideal. It is necessary to modify the attapulgite to obtain high-purity and excellent performance attapulgite.
