How to choose sand/media for your project?

How to choose sand/media for your project? Discover what types of sand are used in the process and which ones will work best on a variety of different surfaces.
 
1. Sandblasting is a type of abrasive blasting that uses sand and compressed air to remove paint, rust, and other surface contaminants
2. The most common types of sand used in the process are silica-based sands like quartz or silicon carbide
3. There are two ways you can choose your sand - by particle size (fine, medium) or by material (silicon carbide). 
4. Silicone carbide is typically preferred because it's more durable than fine silica sands.
5. Using the right sand media will save you time and get great results.

So what is the best media for sandblasting? Actually, it depends on your applications, such as removing the rust, painting or dirt on, etc., by sandblaster gun with following media/sand to reference.
 
*Aluminum Oxide Grit:
An extremely sharp, long-lasting blasting abrasive that can be recycled many times. It is available in 99.5% pure white grade and commonly standard brown. It is often used in surface treatments and preparations.
 
*Soda: 
Soda abrasive is from baking soda or bicarbonate of soda. It offers non-destructive cleaning and is very popularly used by operators. It removes rust from metals without causing depression or damaging the metal beneath the rough surface.
 
*Coal Slag / Aluminum Silicate:
It is a dispensable abrasive, which is a by-product of coal-fired electric power generation plants. It has less dust than Copper Slag. It is often used in open blasting operations in the oil- and shipyard industry and other metal surface treatments.
 
*Crushed Glass Grit:
Crushed Glass Grit is 100% recycled glass beads and is considered to be eco and health-friendly as it eliminates the presence of airborne carcinogens. It is non-toxic and non-hazardous. This is used in profiling and removal of coatings and surface contamination and can be used around water.
 
*Steel Grit:
Softer than Aluminum Oxide Grit but still have a very high hardness quality. It has very fast stripping action and shot peening applications. It is commonly used in cleaning, etching and surface preparations.
 
*Staurolite:
It is a Silicate of Silica and Iron and is generally used to remove thin coatings, rust, and mill scale. Its sub-angular shape is ideal for applications where a minimal surface profile is required. Perfectly used in stripping off surfaces in storage tank & tower construction, structural & plate steel blasting, and steel fabrication.
 
*Glass Beads
Glass Beads are manufactured into preformed ball shapes which is very effective in leaving very smooth surfaces. It produces a super smooth and brighter finish compared to angular abrasives. Glass Beads can be recycled approximately up to 30 times.
Commonly used for automotive restoration, stainless steel fabrication, polishing of castings and light deburring of metal molds and parts.
 
*Steel Shot
Steel Shot is manufactured into a spherical pellet-type abrasive made from carbon steel. It often produces a very smooth surface after use.
Steel shot abrasive is often used in cleaning and polishing metal surfaces and parts in automotive, aerospace, construction, foundry, shipbuilding, rail, and more.
 
*Steel Grit
Softer than Aluminum Oxide Grit but still have a very high hardness quality. It has very fast stripping action and shot peening applications. It is commonly used in cleaning, etching and surface preparations.
 
*Corn Cob Grit
Corn Cob Grit is an organic, soft and natural abrasive from hard cob. It is tumbling and absorbent that dries surfaces. Corn cob grit is non-toxic and safe for operators. It is best used on wood surfaces and does not create any damage on the treated surface. It is used in oily and moist surfaces that quickly absorb it while finishing rough parts.
 
*Walnut Shell Grit
It is a very versatile soft abrasive, organic and biodegradable. Same as corn cob, it is non-toxic and imposes no hazard on health. Best used in stripping and cleaning delicate surfaces and parts, Walnut Shell Grit provides effective applications such as cleaning hardwoods and aircraft and automotive stripping.
 
*Copper Slag / Iron Silicate
In contrast to its name, it contains almost no copper. It is referred to as the best abrasive to use when ranked on cutting speed and cost per sq. ft. It comes in extra fine grade abrasive that is used for surface blast-cleaning carpets, plastic and wood.
 
*Garnet
Garnet is a natural silicate mineral deposit. It has a high stripping rate, very low dust and the lowest consumption rate. Mainly used for wet or dry sandblasting and offers excellent coating preparation and adhesion properties.
