Minerals Pool Filter Sand
The physical density of quartz sand refers to the density of the quartz sand itself, and the bulk density varies greatly depending on the product. For example, the quartz sand that is crushed into sand after processing has a density of 1.3-1.8 tons per cubic meter.
Send InquiryIntroduction
The quartz sand filter for water treatment uses high ore density and high hardness. After calculation, the fine sand with a specification of 0.5-1mm 1-2mm 2-4mm has a specific gravity of 1.5 tons / m3 and a specification of 4-8mm The grit of 16mm 16-32mm is 1.8 tons / m3.
The physical density of quartz sand refers to the density of the quartz sand itself, and the bulk density varies greatly depending on the product. For example, the quartz sand that is crushed into sand after processing has a density of 1.3-1.8 tons per cubic meter. between! The physical density of quartz sand is often greater than the bulk density and the data is relatively stable. The physical density of quartz sand is generally 2.63 tons per cubic meter, and the physical density of quartz sand is about twice the bulk density.

Equipment characteristics
The specific gravity of quartz is 2.65, and 2.65 is true density = equivalent to the true density under the complete crystal structure of SiO2. 1.6 Bulk density = a certain number of sands, which are stacked with a gap in the middle. Divide the weight of this pile of sand by the volume of the pile. Throw the sand into a measuring cylinder with water and see how much the volume changes. Divide the mass of the sand by the volume to get the true density.
The density of quartz sand, the bulk density of quartz sand, and the specific gravity of quartz sand also depend on the purity of quartz sand (but the effect of purity is very small). The size of quartz sand can also affect the density, bulk density, and specific gravity of quartz sand. . It is generally believed to be between 1.6-1.7.
Test method for density of quartz sand filter gravel for water treatment:
The density of quartz sand is determined by grouping according to the paving layer and particle size range of the gravel support material. Before the measurement, the sample was washed and dried to a constant amount, and was measured according to the following steps.
Samples with a particle size of 2 to 4 mm were measured according to regulations.
For samples with a particle size of 4 to 8MM or 8 to 16MM, weigh 300G and slowly add it to a 500ML graduated cylinder containing 250ML (V1) of water that has been boiled and cooled to about 20 ° C. Rotate and tap the graduated cylinder with your hand to drive out air bubbles. After standing for 1H in a constant temperature water tank at 20 ± 1 ° C, pat the measuring cylinder by hand to drive out air bubbles, and record the volume of the water surface in the measuring cylinder (V2).
For samples with a particle size of 16 to 32MM, weigh 1000G, use a 1000ML graduated cylinder, and add 500ML of water. For samples with a particle size of 32 to 64MM, weigh 1500G, use a 2000ML graduated cylinder, add 1000ML of water, and measure in accordance with the above method.
