The difference between quartz sand filter material and ordinary quartz sand

1. Ordinary quartz sand.

Ordinary quartz sand is generally a kind of water treatment filter material made of natural quartz ore, which is crushed, washed, dried and screened for secondary screening. This quartz sand has:

No impurities, no calibration angle, high density, high mechanical strength, and long service life of the dirt-carrying capacity line. It is an ideal material for industry, chemistry, water treatment, etc. In addition, there is a kind of natural quartz sand that is widely used by experts and is also listed by experts as the category of ordinary quartz sand, natural quartz sand refers to not broken by quartz stone, but by the natural formation of the particles are not uniform enough, the quartz content is low, most of the quartz sand formed in water or seawater, has been widely used in many large factories, such as sea sand, natural sand, etc.

Ordinary quartz sand is mainly used in glass and glass products, enamel, cast steel, water filtration, bubble alkali, chemical, spraying and other industries.

2. Refined quartz sand.

Refined quartz sand also uses quartz stone as raw material, but its production industry is more complicated than ordinary quartz sand.

Selected high-quality ores are processed in complex ways. Particle size range: 2-2500 mesh, can be produced according to user requirements, white or crystalline appearance. Main uses: high-grade glass, glass products, refractory materials, smelting stones, precision casting, grinding wheel abrasives, etc.

Third, the production process is different.

Ordinary quartz sand is only a finished product after simple crushing, washing and drying, and the impurity content of the finished product is relatively high, and it can be clearly seen that there is yellow skin.

Refined quartz sand adds more elaborate screening steps to the production steps of ordinary adaptation, including: raw ore screening, strong magnetic separation and flotation steps. Raw ore screening:

Because the tailings still contain some debris with large particle size or diameter, and the laboratory adopts a flat ring wet strong magnetic separator, the particle size is allowed to be too large and flotation.

In the process, for the characteristics of large-particle minerals that are difficult to effectively sort, the refined quartz sand experiment is pre-screened for the prepared test samples, and the laboratory uses 32 mesh (0?

5mm) sieve for grading treatment.

Strong magnetic separation: Because the raw ore contains iron-containing impurity minerals such as hematite, hornblende, garnet, etc., they are all strong magnetic minerals, which can be removed by strong magnetic method, laboratory.

Flat ring wet strong magnetic separator is adopted, and the magnetic field strength. After the quartz sand is pre-classified, the tailings are sieved after processing. The results of magnetic separation show that when the magnetic field strength is 13000 (OE) and the concentration is 65%, the SiO2 of quartz sand concentrate (non-magnetic) is produced by magnetic separation.

At the same time, Fe2O3 in magnetic products and medium ore has been enriched to a large extent, indicating that magnetic separation has a significant promoting effect on the selection and purification of quartz sand.

Quartz sand filter material is made of natural quartz ore as raw material, processed by crushing, washing, screening and other processes, and is the largest and most widely used water purification material in the water treatment industry.

Quartz sand filter material has no impurities, compressive and wear-resistant, high mechanical strength, stable chemical properties, strong dirt interception ability, high efficiency, long service life, suitable for single-layer and double-layer filter pools, filters and ion exchangers, and all indicators have reached the (CJ T43-2009) standard. Refined quartz sand, pure white quartz sand, acid treatment agent, ordinary quartz sand are processed to meet the needs of different users.

Common specifications: 1-2mm2-4mm

4-8mm8-16mm

16-32mm。It is made of natural quartz ore through crushing, screening, washing and other processes. The appearance is polygonal, spherical, pure white, and has the advantages of high mechanical strength, strong dirt interception ability, and good acid and alkali resistance.

Ordinary quartz sand is generally made of natural quartz ore, which is crushed, washed, dried, and screened twice, with SIO2 90-99%.

Fe2O3, refractory 1750, appearance: some large particles have yellow skin cysts on the surface. Main uses: metallurgy, ink silicon carbide, glass and glass products, enamel, cast steel, water filtration, bubble alkali, chemical, spraying and other industries.

In fact, the gap is not big, one is a more accurate classification and the other is a more general classification, quartz sand filter material has a fixed particle size, silica content and other indicators, while ordinary quartz sand covers a wide area, and there are not so many fine index requirements.

Quartz sand filter media filters the water quality, just like the water penetrates into the ground through the sand and gravel, blocking the suspended matter in the water, mainly for those fine suspended solids. Quartz sand filters are also sometimes used to remove manganese and iron from water.

Quartz sand is a quartz particle made of quartz stone by crushing and processing, quartz stone is a non-metallic mineral, is a hard, wear-resistant, chemically stable silicate mineral, its main mineral component is SiO2, the color of quartz sand is milky white, or colorless translucent, Mohs hardness 7, quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastics, rubber, abrasives, filter media and other industries.

The difference between quartz sand and ordinary sand is mainly how much silica is contained.

In addition to silica particles, ordinary sand has a large number of impurities of other oxide minerals, such as feldspar, etc., and the silica content is very low.

Quartz sand is basically relatively pure silica, and the content of silica is generally above or even above.

High purity, low processing cost, easy to purify and manufacture.

Manganese sand contains mnO2, mnO2 is an oxidation catalyst, ** manganese can oxidize the divalent iron in the water into ferric iron, and at the same time form a catalytic "active filter membrane" on the surface, and the active filter membrane formed is attached to the surface of the manganese sand to further participate in catalytic oxidation, so the pre-treatment effect is better if the manganese sand is used as the filter material, the effluent quality is good, and the filter material has a short maturity cycle.

Most of the quartz sand filter material is produced from sea sand or river sand, and some natural quartz ore is used, which is crushed, washed, screened, pickled, dried, and screened twice. Due to the low cost of quartz sand, many water treatment projects only require simple treatment of water quality (impurities such as sediment and other impurities in the water) in order to save costs, or the water quality is not tested after treatment, so quartz sand is the most widely used and largest water purification material.

In the case of mixed use of quartz sand and manganese sand, the quartz sand must be at the bottom layer, and the filter layer must be manganese sand.

Difference: Manganese sand is the removal of iron and manganese from groundwater.

Quartz sand is a supporting layer that removes impurities in the water.

Similarities: Both manganese sand and quartz sand media are placed in water.

1. Both can be removed from sediment, particulate suspended solids, algae and solid impurities in the water;

2. Quartz sand is white crystalline, large and small according to the number of meshes; Manganese sand is granular reddish-brown;

3. Quartz sand mainly removes the excess iron in the water (the iron exceeds the standard, the water quality is yellow, and the water drips to the ground for a long time to form yellow imprints, or leaves obvious yellow substances on the pool wall); Manganese sand mainly removes excess manganese in the water (manganese exceeds the standard, the water quality is reddish-brown, and the water drips to the ground for a long time to form reddish-brown imprints, or leaves obvious reddish-brown substances on the wall of the pool);

4. The market of manganese sand is much more expensive than quartz sand;

5. The use of quartz sand is relatively wide, and the use of manganese sand is relatively rare, which is often used in well water treatment;

6. In water treatment, we often call it: quartz sand filter, manganese sand filter;

7. According to the situation that the water quality of iron and manganese exceeds the standard, quartz sand and manganese sand can be used at the same time or separately;

Manganese sand filter material: because the manganese sand filter material contains mNO2, mno2 is a catalyst, ** manganese can oxidize the divalent iron in the water into ferric iron, and at the same time form a catalytic "active filter membrane" on the surface, and the active filter membrane formed is attached to the surface of the manganese sand filter material to further participate in catalytic oxidation, so the pre-treatment effect is better if the manganese sand is used as the filter material, the effluent quality is good, and the filter material has a short maturity cycle. After treatment, it meets the national drinking water sanitation standard "GB5749-2006", iron, manganese.

Quartz sand filter material: quartz sand filter material is a kind of water treatment filter material made of natural quartz ore, crushed, washed, screened, pickled, dried, and screened twice, widely used and large amount of water purification materials, no impurities, compressive and wear-resistant, high mechanical strength, stable chemical properties, strong dirt interception ability, high efficiency, long service life, suitable for single-layer and double-layer filter pools, filters and ion exchangers, and all indicators have reached the (CJ T43-2005) standard. However, when it is used to remove iron and manganese, the maturity cycle of the filter material is long before use, and the effluent quality in the early stage is not good.

After the filter material is mature, the effluent quality reaches the national drinking water hygiene standard "GB5749-2006" iron and manganese.

Summary. Pro, the difference between quartz sand and sand:

The difference between quartz sand and sand.

Pro, the difference between quartz sand and sand:

1. The hardness is different, and the hardness of ordinary sand cannot be compared with the hardness of quartz sand.

2. The difference between quartz sand and ordinary sand with different silica content mainly lies in the silica content, in addition, quartz has high refractory performance, and generally quartz sand is used for casting, and the high temperature resistance is 1750 degrees, so this is also an important aspect of the difference between quartz sand and ordinary sand.

3. Quartz sand with different purity is a sand particle with high purity, mainly silica, which contains a small amount of iron minerals, and quartz sand is processed by special processes such as natural quartz stone mineral crushing, selection, magnetic separation, and gravity separation. And ordinary sand does not have such a high purity.

4. Different uses because ordinary sand has a corrosive effect on metals and buildings, so ordinary sand does not dare to use it in construction, but the use of sea sand is also very wide, and the demand for sea sand in the market is very large.

5. The composition is different, in addition to silica particles, ordinary sand has a large number of impurities of other oxide minerals, such as feldspar, etc., and the silica content is very low. The quartz sand is basically relatively pure silica, generally the silica content is high in or even above purity, the processing cost is low, easy to purify and manufacture, all the sand contains quartz, whether it can be made of glass depends on the content of quartz.

Quartz sand is a quartz particle made by crushing quartz stone. Quartz is a non-metallic mineral that is a hard, wear-resistant, chemically stable silicate mineral. The color of quartz sand is milky white, or colorless translucent, with a hardness of 7 on the Mohs scale.

Dear, hello, I am happy to serve you, the answer is as follows: The biggest difference between the sand of quartz sand should be the slippery content of silicon, the silica content of quartz sand is high, and the impurities of the sand are excessive. Quartz sand is an important industrial mineral raw material, non-chemical dangerous goods, widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. It can be transported by car, train and water.

The difference between quartz sand and ordinary sand is mainly in the silica content, in addition to silica particles, there are a large number of impurities of other oxide minerals, such as feldspar, etc., the silica content is very lowQuartz sand is basically relatively pure silica, the general silica content is high or even above, the purity is high, the processing cost is low, and it is easy to purify and manufactureThe difference between quartz sand and ordinary sand is mainly how much silica content is ordinary sand in addition to silica particles. There are a large number of impurities of other oxide garbled minerals, such as feldspar, etc., the silica content is very low, quartz sand is basically relatively pure silica, generally the silica content is high or even above, the processing cost is low, and it is easy to purify and manufacture.

Quartz sand filters are often set after the pressure filter to remove fine particles in the liquid to meet the subsequent process alignment.

Water requirements. Sometimes it is also installed at the end of the complete water treatment system to prevent fine particles from entering the finished water.

Commonly used filter elements are hive filters and meltblown filters.

The accuracy of the filter element is measured in microns (m) and has the following specifications: , which can be selected according to different requirements.

Quartz sand filtration is often used as a security filter for electrodialysis, ion exchange, reverse osmosis, ultrafiltration and other devices.

Generally, it is used for about 3 6 months or when the inlet and outlet pressure difference (P2-P3) is greater than the replacement to ensure the pretreatment effect and prevent the reverse osmosis membrane from being damaged by particles and suspended solids.

1. Inlet and outlet diameter: In principle, the inlet and outlet diameter of the quartz sand filter should not be smaller than the inlet diameter of the matching pump, which is generally consistent with the diameter of the inlet pipeline.

2. Nominal pressure: determine the pressure level of the filter according to the pressure that may occur in the filter pipeline.

3. The selection of the number of meshes: the main consideration is the impurity particle size that needs to be intercepted by the quartz sand filter, which is determined according to the requirements of the medium process.

4. Filter material: The material is generally the same as the material of the connected process pipeline, and the filter made of cast iron, carbon steel, low alloy steel or stainless steel can be considered for different use conditions.
