Pyrophyllite is typically marketed as a powder, produced by crushing and grinding raw ore. This powder is used in construction, as filler, and more. Especially in high-end sectors like ceramics and electronics, highly purified pyrophyllite powder is sought after.

What wonders does Pyrophyllite hold?

Pyrophyllite, a silicate mineral represented by the chemical formula Al2Si4O10(OH)2, is frequently discovered alongside minerals like quartz, mica, and kaolin. It boasts a soft texture, ranking at 1每2 on the Mohs scale, and typically exhibits a radial or leaf-like structure.

This mineral is found in a variety of colors, including brown-green, brown-yellow, gray-green, and gray-white. With a low coefficient of expansion and high-temperature resistance, pyrophyllite transforms mullite, a material with stable chemical properties, at approximately 1200∼C.

Pyrophyllite is commonly processed into powder and commercialized. There is a rising industrial demand for low-purity pyrophyllite powder. However, due to the presence of impurities, the application of low-purity pyrophyllite powder is still limited, and high-purity pyrophyllite powder has emerged.

How to Process Low-Purity Pyrophyllite Powder?

Low-purity pyrophyllite powder typically contains 10%每20% Al2O3 and is directly sold post-crushing and grinding. This type of powder finds wide application in building materials, fillers, and other general uses. For processing, a jaw crusher is recommended for crushing, while grinding can be done using a ball mill or Raymond mill.

Crushing

For pyrophyllite with a fine texture and low hardness, a jaw crusher is a preferable choice. At this point, the jaw crusher must reduce the pyrophyllite to a size less than 25 mm. Once the particles are reduced to this size, they proceed to the grinding stage.
