PYROPHYLLITE CRUSHER

Pyrophyllite is a phyllosilicate mineral composed of aluminium silicate hydroxide: Al2Si4O10(OH)2. It occurs in two more or less distinct varieties, namely, as crystalline folia and as compact masses; distinct crystals are not known.
The folia have a pronounced pearly lustre, owing to the presence of a perfect cleavage parallel to their surfaces: they are flexible but not elastic, and are usually arranged radially in fan-like or spherical groups. This variety, when heated before the blowpipe, exfoliates and swells up to many times its original volume, hence the name pyrophyllite, from the Greek pyros (fire) and phyllos (a leaf), given by R. Hermann in 1829. The color of both varieties is white, pale green, greyish or yellowish; they are very soft (hardness of 1 to 1.5) and are greasy to the touch. The specific gravity is 2.65 - 2.85. The two varieties are thus very similar to talc.
Pyrophyllite occurs in phyllite and schistose rocks, often associated with kyanite, of which it is an alteration product. It also occurs as hydrothermal deposits. Typical associated minerals include: kyanite, andalusite, topaz, mica and quartz.
Deposits containing well-crystallized material are found in:
Russia - pale green foliated masses, very like talc in appearance, are found at Beresovsk near Yekaterinburg in the Urals.
St. Niklas, Zermatt, Valais, Switzerland
at Vaastana, Kristianstad, Sweden
near Ottrje, Ardennes Mountains, Belgium
Ibitiara, Bahia, Brazil
Nagano Prefecture, Japan
USA
It is found near Ogilby, Imperial County at Tres Cerritos, Mariposa County, and the Champion mine, White Mountains, Mono County, California
near Quartzsite, La Paz County, Arizona
the large deposits at the Deep River region of North Carolina
Graves Mountain, Lincoln County, Georgia
It is also reported from South Africa where major deposits of pyrophyllite occur within the Ottosdal region, where it is mined for the production of a variety of manufactured goods and blocks are quarried and marketed as "Wonderstone" for the carving of sculptures.
Uses
The compact variety of pyrophyllite is used for slate pencils and tailors chalk (French chalk), and is carved by the Chinese into small images and ornaments of various kinds. Other soft compact minerals (steatite and pinite) used for these Chinese carvings are included with pyrophyllite under the terms agalmatolite and pagodite.
Pyrophyllite is easily machineable and has excellent thermal stability. Therefore it is added to clay to reduce thermal expansion when firing but it has many other industry uses when combined with other compounds, such as in insecticide and for making bricks. Pyrophyllite is also widely used in high-pressure experiments, both as a gasket material and as a pressure-transmitting medium.
Crushing Plant & Portable Crushing Plants
The crushing plants inlcude jaw crushing, cone crushing, impact crushing etc. Jaw crusher crush raw materials as primary crusher. Cone and impact crusher work as secondary crusher. Grinding plant include ball mill, raymond mill etc. The mills grind materials into smaller fine powder for deep usage.
Zenith produce not only crushing plants for this kind of mineral but also plants for kinds of minerals and ores. The productions include aluminum ore crushing line, barite grinding plant, coal crushing plant, gold ore crushing plant, magnetite ore screening plant, track ballast crushing line, iron ore crushing plant, quarry plant, nickel crushing and grinding plant, antimony ore crushing plant, construction aggregate plant, cement grinding plant, sand making production plant, copper ore crusher and mills, coal preparation plant, mining and crushing plant, construction waste crushing and treatment equipment, washing sand plant, track mounted aggregate plant, granite crushing plant, iron ore crushing plant, etc.
