Product Introduction
Pyrophyllite’s hardness is 1-2 in Mohs. It is a kind of widely used mineral in industrial production industry, especially for the production of refractory materials, refractory brick, ceramics, paper making, pesticide carriers and so on. When making tiles with pyrophyllite, the amount of pyrophyllite is about 50%-60% and the rest is clay, limestone and china stone. Pyrophyllite can produce refractory bricks and white cement.
Technical Process
1. The processing flow of pyrophyllite is determined according to the requirement of the products. If the pyrophyllite is used to produce refractory materials and refractory bricks, the whiteness and the granularity are not high. When used to produce bricks, the granularity of the pyrophyllite is 3mm. It is usually dry production: pyrophyllite raw ore→ore washing→jaw crusher→roller crusher(edge runner mill)→finished product
2. If the pyrophyllite is used for ceramics, paper making and pesticide carrier.etc, the fineness requirement is below 200mesh, and the whiteness is above 85%. At this process, in addition to coarse crushing, medium crushing and fine crushing, high pressure suspension grinder is also used to crush. To select the ore, even bleaching is required. For most cases, wet production is adopted: pyrophyllite raw ore→ore washing→coarse crushing(crusher)→medium crushing→fine crushing→grinding(grinder)→reelection or flotation(flotation machine)→grading(sedimentation tank or hydrocyclone)→purification(bleaching)→filtration(pressure filtration)→drying(natural drying or chain plate drier)→micropowder crushing(super fineness grinder)→finished product
3.If the pyrophyllite is used to produce tiles, its amount is about 50%-60% and the rest is clay, limestone and china stone. raw material→crushing(crusher)→ore grinding(grinder)→filtration→dry→biscuiting→glazing→glaze firing
4.If the pyrophyllite is used to produce refractory brick, the principle process is: raw material→crushing(crusher)→wet grinding and mixing→pressure formation of brick and molding→tunnel kiln
5. If the pyrophyllite is used to produce white cement, the main process is: pyrophyllite+limestone→grinding→mixing→briquette→calcination
