Washed Silica Sand 200 – 500 micron

After mining, silica sand goes through a washing and rinsing process to become washed silica sand. Clay, salt, and other powders and particles are removed from the combination. It usually goes through extra separation and grading into grit sizes. Sizes of granules for washed silica sand include medium, coarse, fine, and ultra-fine. Also, it is utilized in many different industries, including foundries, glass, ceramics and refractories, abrasives, filtration, oil well cementing, and metallurgical silicon.

Washed silica sand in the 200-500 micron size range is a fine to medium-grade sand that has undergone a washing and cleaning process to remove impurities, silt, clay, and other contaminants. This results in a high-purity, clean, and consistent product suitable for various industrial and commercial applications. Here’s a description of washed silica sand in the 200-500 micron size range:

1. Particle Size Range: Washed silica sand in the 200-500 micron size range consists of fine to medium-sized grains, with most particles falling between 0.2 millimeters (200 microns) and 0.5 millimeters (500 microns) in diameter. This size range is considered ideal for many applications requiring fine to medium sand.
2. Purity: Washed silica sand is typically high in purity, containing a minimum of 95% silicon dioxide (SiO2). The washing process removes impurities and contaminants, ensuring a clean and consistent product.
3. Color and Texture: Washed silica sand is often light-colored, such as white, beige, or pale yellow. It has a fine to medium texture, feeling smooth and granular to the touch.
4. Chemical Composition: The primary chemical component of washed silica sand is silicon dioxide (SiO2), making it chemically stable and resistant to most chemicals and environmental factors.
5. Industrial Uses:
   • Construction: This size of washed silica sand is commonly used in construction applications, including mixing with cement to create mortar and grout, enhancing workability and texture.
   • Sandblasting: It can be used as an abrasive material in sandblasting applications, particularly when a fine to medium abrasive action is required for surface preparation and cleaning.
   • Manufacturing: In manufacturing processes such as glass production and ceramics, washed silica sand is a key ingredient for its purity and consistent particle size.
   • Foundry Casting: It is sometimes used in foundry casting to create molds and cores for metal casting due to its ability to provide fine detail and dimensional accuracy.
   • Water Filtration: In certain water filtration systems, particularly in swimming pools and aquariums, washed silica sand in this size range can be used as a filter medium to remove small particulate matter from water.
6. Landscaping: Washed silica sand of this size can be used in landscaping applications such as topdressing lawns, creating sandboxes, and enhancing soil drainage.
7. Sports Fields: In sports field construction, particularly for golf course bunkers and sports turf, this size of washed silica sand is used to create stable and playable surfaces.
8. Agriculture: In agriculture, it may be used in soil mixtures to improve soil structure, aeration, and drainage, especially in horticultural and greenhouse applications.

Washed silica sand in the 200-500 micron size range is a versatile material prized for its purity, consistency, and fine to medium particle size. Its suitability for various applications makes it a valuable resource in construction, manufacturing, filtration, and landscaping industries, among others.
