water filtration abrasive - abrasive30/60

Available model: CN Garnet abrasive and CN Jadeblast abrasive
Specification：30/60mesh
General: Garnet is a naturally occuring mineral (Almandine) with very uniform physical chemical and micro-structural properties. There are no free elements, all oxides are combined chemically as an iron rich aliminosilicate.
Characteristics: Grain Shape Blocky, angular, irregular, conchoidal.
Specific gravity 4.10
Bulk Density 2.10 tonne/m3 (finest to coarsest).
Hardness 7.5 - 8 Moh.
Acid Solubility Insoluble.
Typical
Chemical Analysis: SiO2 38% (No free silica)
Al203 19%
FeO 22%
Fe2O3 3%
ZO2 1%
CaO 12%
MgO 5%
Grades Available: The most common sizes used in Water Filtration are 0.3 / 0.6mm and 1.4 / 2.36mm.
However, almost any size between 0.1 and 3.00mm can be made for customers specific requirements
Quality Control: Garnets are available that are certified for use in potable water systems. These special garnets do not release any toxic substances into the water supply.
Specific Grades of Garnet: High Specific Gravity gives more control during critical
backwash operations, less media is lost to the overflow tanks.
Angular, grains yield more pore space than rounded grains. This gives improves the ability to clean the water and lengthens filter runs.
Garnet is a naturally hard, durable mineral so its breakdown rate is very small
