What does natural sand do? Introduction to natural sand

.Silica sand and quartz sand for the construction industry, glass industry or cleaning metals, etc. Soil sand, including kaolin sand, is mainly used to make casting molds and refractory products. Feldspar sand is used in the ceramic industry.

Natural sand that has been heat-treated to remove impurities is still included in this heading.

Sand and sand "sand" is a natural particle gradation, without the restriction of sludge, dirt, and debris, and is a general name.

"Sand" means soil that can be used as a building material and has certain quality requirements. For example, highly weathered granite grains cannot be called "sand", although they are very similar, but the main factor is that they have no strength mass.

Since it's natural, how can it still be made.

The composition of sand is mainly silica.

Rock particles formed by natural conditions (mainly rock weathering) with a particle size of less than 5mm.

Natural sand. Comparison with artificial sand:

Compared with natural sand, artificial sand has the following differences and advantages: the material of artificial sand washing is excellent and stable. Artificial sand washing is an artificially selected raw material, and the material is uniform.

1. Stable, the mineral composition and chemical composition are consistent with the raw materials, and are not as complex as natural sand. The sand grains are clean, free of mud and other harmful impurities, and the performance is stable.

A kind of artificial sand washing, a fineness modulus.

Only one gradation corresponds. Its fineness modulus is linearly related to the sieve allowance of a single sieve. As long as the linear relationship is established through measurement, and the sieve allowance of a single sieve is measured, the fineness modulus can be accurately and quickly obtained.

The general natural sand, a fineness modulus, can have a variety of gradations.

1. Natural sand is mainly used in construction, concrete, cementitious materials, road construction materials, artificial marble, cement physical property inspection materials (i.e., cement standard sand), etc.

2. River sand can also be used in casting, forging machine, metallurgy, heat treatment, steel structure, frame structure, container, shipbuilding, construction, bridge, mining, and other fields of sand removal, rust removal, strengthening, forming, stress relieving and surface cleaning and coating of various profiles, roughness before electroplating, (brushing) pretreatment, cutting, magnetic shot casting, as an additive for heavy-duty coagulation and high-temperature refractory materials, so as to increase its wear resistance, high temperature resistance, erosion resistance, electrostatic shielding, radiation protection, oil well filter tank, counterweight, etc.

Quartz sand is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgy, construction, chemical industry, plastics, rubber, abrasives and filter materials and other industries, and is also an ideal material for modern track and field fields, football fields, golf courses and other man-made venues.

Sea sand is the sand and gravel in the sea, mainly for machinery, casting sand as the main raw material, can also be used for grinding materials, sand cleaning, rust removal, oxide scale removal treatment ceramics and refractory materials.

How to choose between natural sand and machine-made sand

1. Natural sand for daily use, with a sleek and hard texture, is an ideal material. However, due to the large number of raw materials it produces, it will be slightly more complex in formation, and even have unstable components, so special attention should be paid to it.

2. After a long period of continuous mining, the amount of natural sand will become less and less, resulting in a situation where supply exceeds demand, which eventually leads to its high quality and difficult to guarantee. However, machine-made sand is different in that it can be produced wherever there are stones.

3. Before purchasing sand, you also need to consider the issue of environmental protection. If traditional machine-made sand equipment is used, it will produce ring dust pollution in the production process. However, after the production of new equipment, the generation of dust can be reduced and will not cause pollution.
