White Bentonite Powder Factory – industrial perlite ore for foundry manufacturers – Xinzheng Cheng Detail:
Introduction of perlite ore
Perlite is a kind of volcanic eruption acid lava, vitreous rock formed by rapid cooling. Perlite ore is a raw ore product made by crushing and screening perlite ore. Various specifications of perlite products can be made according to the needs of customers.
Production Process of perlite ore
Raw ore (crushing, drying)→coarse crushing 21mm～40mm(grinding)→medium crushing 5mm(grinding, sieving)→fine crushing 20 mesh～50 mesh (screening)→50～70 mesh～90 mesh～120 mesh ～200 mesh→bagging (grading)
The main physical properties of perlite ore
Color: yellow and white, flesh red, dark green, gray, brown brown, black gray and other colors, of which gray-white-light gray is the main color
Appearance: Ragged fracture, conchoidal, lobed, white streaks
Mohs hardness 5.5~7
Density g/cm3 2.2~2.4
Refractoriness 1300~1380°C
Refractive index 1.483~1.506
Expansion ratio 4~25
General chemical composition of perlite ore (%)
Ore type : SiO2 Al2O3 Fe2O3 CaO K2O Na2O MgO H2O
Perlite : 68~74 ±12 0.5~3.6 0.7~1.0 2~3 4~5 0.3 2.3~6.4
The main industrial indicators of the deposit
The industrial value of perlite raw materials is mainly determined by their expansion ratio and product bulk density after high-temperature roasting.
1. Expansion multiple k0>5~15 times
2. Bulk density≤80kg/m3~200 kg/m3
The main Application of perlite ore
The raw perlite sand is finely pulverized and ultra-finely pulverized, and can be used as a filler in rubber and plastic products, pigments, paints, inks, synthetic glass, heat-insulating bakelite, and some mechanical components and equipment.
