30 mesh sand can be classified into a few types based on its source, shape, application, and performance. They are as follows:
The sifting diameter of 30 mesh sand is between 0.595 mm and 0.021 inches (same as 16-30 mesh range generally). Its round grain shape is mostly composed of quartz or other hard minerals. It has a bulk density of about 1.5 g/cm3 and a loose density of about 1.1 g/cm3. The porosity is about 40%, and the voids volume is about 0.6 cm3/g.
15-30 mesh silica sand is used in many fields, such as making glass, gravel packs, foundry casting, filtration, construction, etc. Because of its numerous uses, it is usually mined industrially. In many countries, people excavate silica sand from the earth through open-pit mining or dredging. However, the mining methods may vary depending on local laws.
After mining, people will wash it with water and a sand washer machine to remove impurities like clay, silt, or dust. It will improve the quality and whiteness of the sand. Then the silica sand will be laid out to dry in the sun. People will use different sand sieving machines to screen and separate it further according to the required grain sizes.
30 mesh sand has very tiny granules. Therefore, when using it for sandblasting or other applications, it is essential to store it in a dry place and protect it from water so that it will not form a big lump. If it gets some moisture, people can dry it out by putting it in the oven for one hour at about 200 degrees Fahrenheit/93 degrees Celsius. Besides, mixing additives during the storage process will help keep the sand dry and free-flowing.
30 mesh silica sand should be stored in sealed containers with additives or in places where it will not be contaminated by any harmful substances. Sealed containers will also make transportation easier, and using silica sand for fracking in the oil and gas industry will be cost-effective.
For many applications in the machinery industry and others, 30 mesh sand plays a critical role. Here are some industry sand scenarios where 30 mesh is used.
Glass production
In glass manufacturing, quartz 30 mesh sand is a key ingredient. Its unique qualities, like negligible expansion when heated and significant breakdown resistance, make it perfect for high-performance glass. Items such as bottles, windows, and containers all utilize this kind of sand. Granada recommends 30 mesh quartz for partners in the glass industry.
Abrasive products
30 mesh sand serves as a foundational element in crafting abrasive items. Materials like sandpaper and emery boards depend on this specific grain size. Larger particles would yield an undesirably coarse surface. Conversely, finer ones might not deliver adequate abrasion.
The goal is to achieve a balance of grindability and smoothness. The durability and functionality of these abrasive products heavily depend on the variety of sand employed.
Concrete and Mortar
The balance between fine and coarse aggregate is influenced by using 30 mesh sand, which affects workability, strength, and durability. When mixed with cement and water, it yields high-strength concrete and smooth, imperfection-free mortar. Whether the intended construction is a load-bearing structure or a decorative element, this grain size of sand helps achieve the desired function and aesthetic.
Pet Litter
Using 30 mesh sand in pet litter helps achieve optimal moisture absorption and odour control. Its small pieces offer a soft touch, making it comfortable for pets like cats. Additionally, the dust generation is low, ensuring a healthier environment for both pets and their owners.
Water Filtration
The size and form of sand particles are crucial for producing effective water filters. High-quality filtered water is made possible by a solid mixture of 30 mesh quartz sand and gravel. Sand of this size helps in the trapping of impurities, bacteria, and sediments, thus enabling precise straining and superior cleaning capabilities. It plays a significant role in municipal water treatment facilities, private wells, and swimming pool filtration systems.
There are a few things construction business owners should consider when purchasing 30 mesh quartz sand.
End product requirements
Before purchasing the sand, business owners should first determine what their end product will be. For example, if they are producing concrete or asphalt that requires srtand for filler, they need to examine their final product's strength, durability, and appearance requirements.
Source Material's Properties
Business owners need to analyze the properties of the material they are considering to ensure they meet the project requirements. This includes testing for chemical composition and checking the levels of impurities. They should also check the sand's levels of static electricity, as this can lead to issues during mixing and transportation.
Supply Chain Logistics
Where the sand is coming from is also an important factor to consider when purchasing this material. The distance will affect mix cost and consistency. It may also have an impact on the project's environmental sustainability. The sand will likely have a lower carbon footprint if it is sourced locally. People will also have easier access to it, thus reducing delays in project completion.
Cost
Cost is always a huge factor in project budget constraints. Sand that has to be shipped from a longer distance is likely to be more expensive. Consider local options first before exploring international sources like sea sand, which is usually more affordable due to lower shipping costs.
Q1: What does a mesh size of 30 mean for sand?
A1: Mesh sizes describe the number of holes in one-inch of a wire gauge that can sift or separate materials. A mesh size of 30 means 30 holes will fit in one sifter inch. Thus, there will be about one-inch sand particles that can go through the holes. Sand particles are usually larger than one inch, so 30 mesh is a larger size than most.
Q2: Is there any mesh size larger than 30 for sand?
A2: Yes. There are larger mesh sizes for sand, such as 20, 10, 5, and 1. The larger the mesh numbers, the more gaps there will be in one-inch sand. 20 mesh sand is very common in the building industry for concrete. 60 mesh is the most common size for water filtration.
Q3: Does 30 mesh sand have larger or smaller particles than 40 mesh sand?
A3: 30 mesh sand has larger particles than 40 mesh sand. The number system for mesh sizes indicates that more holes exist in one-inch space. So, 40 mesh has more holes than 30, meaning 30 mesh sand will have larger particles.
Q4: Does 30 mesh sand work for swimming pools?
A4: No, it will be too coarse for the filters to catch small debris like leaves or algae. 30 mesh is ideal for concrete mixing and making epoxy for coatings. 40 to 60 mesh is better for swimming pools.
Q5: Can you use 30 mesh sand in epoxy?
A5: Yes. 30 mesh sand is popular in different epoxy applications. Its texture helps create a non-slip surface for coatings and circumvents epoxy's smooth surfaces that can become slippery.
