Pyrophyllite is actually a clay mineral, which belongs to a chemical substance. Because of its low hardness, it is called waxstone. Pyrophyllite is hidden in mines and has a wide range of uses.
The hardness is comparable to that of nails (Mohs hardness: 1 to 2), and the refractoriness is extremely high, up to 1630°C to 1710°C.
Pyrophyllite has good heat resistance and insulation, and is a medium material for sealing and pressure transmission.
Pyrophyllite powder is the product of pyrophyllite after grinding. Due to the properties of pyrophyllite, pyrophyllite powder has a wide range of uses.
Pyrophyllite
Pyrophyllite contains silicon dioxide and aluminum oxide, which does not melt when heated, and is the raw material for making aluminum silicate refractories. Due to the wide range of refractory materials, it is necessary to add some other characteristic minerals to the pyrophyllite mineral materials to form new refractory materials; such as adding mullite mineral materials, the product can improve the impact strength, density, and resistance of products. Heat resistance, refractoriness, corrosion resistance and slag resistance; zircon minerals are added as refractories, which have good durability and strong corrosion resistance to metals and slag.
The pyrophyllite mineral material has high mechanical strength, good heat resistance, high whiteness, and small shrinkage at high temperature. Adding pyrophyllite to the ceramic blank can reduce the firing temperature, shorten the drying time, improve the firing strength, and reduce glaze defects. , so that the ceramic is perfect, it is a good raw material for making ceramics.
Pyrophyllite powder has the characteristics of high whiteness, mostly flaky particles, small bulk density, good fluidity, medium adsorption, low hygroscopicity, dispersibility, general wettability, good suspension and acidity. It can meet the requirements of pesticides and insecticides on the bulk density, adsorption, suspension and acidity and alkalinity of fillers (carriers).
Pyrophyllite can meet the color, hiding power, reinforcement and suspension requirements of coatings for fillers; at the same time, it can also meet the reinforcement performance of composite plastics for fillers and give special functions (such as stagnation) requirements. As a solid sealing and pressure transmission material, the pyrophyllite molecular layers are easy to slide and cause creep, and its own hardness is relatively low, and it has relatively low shear strength and good electrical and thermal insulation, and is cheap and easy to obtain. It is used in the high-voltage synthesis industry. It is widely used as the raw material of pressure transmission sealing medium in China.
Pyrophyllite is used as a filler in paper making, which can increase the density, smoothness, uniformity, softness and print-through of paper.
Pyrophyllite can also be used for plastic and rubber fillers; fillers and brighteners for white cotton cloth and fireproof cloth; candy, pharmaceutical fillers and lubricants; cosmetic ingredients; enamel glaze raw materials; welding rod admixtures; colored pencil leads Adding pyrophyllite can increase the smoothness when writing.
European version coarse powder mill
Maxing Feeding Size: 80 mm
Ouput Size: 0-3 mm
Capacity: 8-100 t/h
Advantages: European Version Coarse Grinding MIll is generally used after jaw crusher, impact crusher or hydraulic cone crusher.
Because the feeding particle size of European version coarse grinding is between 30-50mm, and the discharging particle size is adjustable in the range of 0-3mm, 0-5mm and 0-8mm.
The production capacity can reach up to 100 tons per hour. Uniform discharge and considerable output.
YGM High Pressure Raymond Roller Grinding Mill
Maxing Feeding Size: 40 mm
Ouput Size: 613-33 micron (35-400mesh)
Capacity: 1-25 t/h
Applicable materials: Calcium carbonate, limestone, kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica
Advantages: Raymond mill is a cost-effective fine powder processing equipment. Easy to operate and efficient.
Raymond mill processes pyrophyllite :
The feeder will send large bentonite to the jaw crusher for coarse crushing, and the coarse crushed bentonite materials will be sent to the impact crusher for medium and fine crushing by the belt conveyor. The impact crusher has a very good crushing effect on bentonite; The bentonite with qualified particle size after medium and fine crushing is sent to the storage bin by the bucket elevator, and the bentonite with unqualified particle size is transported back to the impact crusher for further crushing; The vibrating feeder will evenly and quantitatively feed the materials with qualified particle size into the Raymond mill for grinding. The Raymond mill discharge can be adjusted between 80-325 mesh, with high screening rate and fine finished products. The materials grinded by Raymond are sorted by the classifier at the top of the grinding chamber. The qualified materials are sent to the finished material pile, and the unqualified materials are returned to the grinding chamber to continue grinding, forming a closed loop.
HGM Ultrafine Powder Grinding Mill
Maxing Feeding Size: 20 mm
Ouput Size: 74-5 micron (150-2500 mesh)
Capacity: 0.5-45 t/h
Applicable materials: Calcium carbonate, limestone, kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, etc.
Advantages: HGM ultra-fine grinding is very different from Raymond grinding in structure. It adopts a multi-ring, layered grinding structure. Due to its multi-ring, multi-roller structure, it is possible to process finer powders and at the same time be more efficient.
CLUM Ultrafine Powder Vertical Roller Mill
Maxing Feeding Size: 10 mm
Ouput Size: 74-5 micron (400-3000 mesh)
Capacity: 0.5-5.5 t/h
D97 < 4μm
D50 < 2μm
Applicable materials: calcite, marble, limestone, dolomite, barite, talc, kaolin, wollastonite, gypsum, feldspar, pyrophyllite etc.
Advantages: Compared with HGM series ultra-fine mill, CLUM series ultra-fine vertical mill produces higher ultra-fine powder content, better powder particle size, less impurities, and higher ultra-fine powder output. It is more suitable for industries with high requirements on powder.
