THE BASIC OF ABRASIVE BLASTING Six Questions to ask when choosing an abrasive Before selecting a specific abrasive, ask yourself the following questions:

1.F or this particular job, will abrasive blasting be used for surface preparation or as a cleaning procedure?

low-build coatings; insufficient profile can cause delamination of high-build coatings.

The difference between these two procedures is as follows:

5. Will coating adhesion be affected by surface contamination?

• When abrasive blasting is used as a surface preparation technique, the intention is to both remove all surface contaminants and also prepare the substrate to receive a coating.

Some abrasives leave a cleaner surface than others, which can have a substantial impact on coating adhesion.

• When abrasive blasting is to be used as a cleaning procedure, then the intention is to remove only the surface contaminants while leaving the substrate untouched.

6. Which abrasive provides the maximum productivity?

2. W  ill it be possible to reclaim and recycle the abrasive, or will it have a single use only?

• The ideal abrasive size is where the largest particle is equal in size to the thickness of the coating to be removed. If the particle size is too large, the "hit rate" is reduced because the grain count in the pot is lowered. If the particle size is too small, the speed of cutting through the old surface is reduced.

The major deciding factor here is cost. The cost of abrasive varies widely and some abrasives, while very effective, are uneconomical to use if recycling is not an option.

3. Will the work site be dust sensitive? The amount of dust generated by different abrasives varies widely. Some excellent types of abrasive are available that are specifically graded to reduce dust.

4. If blasting for surface preparation, what surface profile is required? All coatings have a recommended surface profile (roughness) specification. Excess surface profile can shorten the life of thin,

Abrasive particle size, toughness, and shape all have an effect on blasting speed. Some factors to consider:

• Grain toughness is term given to describe its durability and recyclability. A tougher grain converts more energy into the removal of the old coating, while a weaker grain is more likely to disintegrate on contact. • Particle shape can either be rounded or angular. The more rounded the particle is, the more contact area it has, which increases the surface removal speed.

11 MILLION GRAINS PER KG

Maximum productivity is provided by an abrasive that has a blend of particle sizes which allows it to cut though the coating and get into pits and crevices.

There is such a thing as too high a profile.

SILICA SAND WARNING

Blasting with silica sands, such as beach sand, river sand and any other crystalline silica sand may cause serious injury or be fatal. Crystalline silica is recognized world-wide as a Class 1 carcinogen.

SPEEDBLAST GARNET Blast-One Speedblast is known world-wide for several important characteristics. Compared to cheap sands and slags, it is much more environmentally responsible and it also offers the potential for major productivity gains, which often makes the overall cost less than the alternatives. Speedblast Garnet - Nature’s own abrasive

Low Dust! Speedblast grains have a high level of toughness. Because of this, much less dust is produced during the blasting process. You can see better, work cleaner and keep neighbours much happier.

Increase Speed! An important distinction of Speedblast is that it is a natural, alluvial grain. Compared to crushed garnets and slags, it is much more rounded in shape. Each grain achieves more work, which allows the nozzle to be moved faster. The larger the project, the more time you save!

Reduce Costs! Tough Speedblast saves money – simple as 1,2,3 1.  Buy less due to lower consumption. 2.  Reduce clean-up labour because you bought less. 3.  Reduce disposal costs because you had less to clean up.

Conventional abrasives can create excess dust.

Which surface would you like your coating system to hold to?

PREMIUM SPEEDBLAST GARNET Blasting Speed 

Dust Factor: Low

Recyclability 

What makes Speedblast Garnet better than other garnets? While the mineral itself is the same as the others, Speedblast Garnet is geologically older. This means it is rounder – kind of like a rock that has been in a tumbler longer. In addition, Speedblast Garnet is cleaner, having a low chloride salt content as compared to Indian Garnet. Speedblast Garnet offers: High Performance removal of mill-scale and coating up to 35 mil thick • Low Dust characteristics • Reasonable cost for single use but recycles well for even lower costs • Low Free Silica content - workplace health and safety compliant • Often used when under 4 mil profile is preferred Blast-One Speedblast Garnet is offered in the following types: New Steel - 80 mesh Ideal for removing mill scale. Cleans out rust pits well. Will give you a profile of 1.5-2.5 mils Speed Blast - 30/60/80 mesh With its wide range of mesh sizes, this abrasive offers the best of both worlds for speed and economy when used in its "sweet spot". Ideal for General Purpose industrial coating work with medium coatings or rust to be removed. Will give a 2-3 mil profile. Premium Blast - 30/60 mesh This is the abrasive to use if you are removing coatings over 15-20 mils or if you need a surface profile between 2.5-3.5 mils. This blend of garnet has larger Particles to remove coatings and rust, and the fine particles to give you the cleanest surface with improved speed! Ideal for General Purpose industrial coating work; with heavier coatings or rust to be removed. Ultra Blast – 30/40 mesh This is the abrasive to use if you are removing coatings over 35 mils or if you need a surface profile of 4 mils. This blend of garnet has larger particles to remove very heavy coatings and rust. Ideal for projects where heavy coating removal is required.

INDIAN GARNET Blasting Speed 

Dust Facto: Medium

Recyclability 

Indian Garnet is mostly mined on the coasts of India. Typical sieve analysis will show coarser particle sizes between 12-60#. Like Speedblast Garnet, Indian Garnet is a natural (not crushed) abrasive. However, Indian Garnet has a reputation for variable cleanliness, and salt and other contaminates are sometimes present. • Available sizes are 12/20, 20/40, and 30/60 mesh • Comes in 55 lb bags or 2000 lb drums • Profile range 2 - 4.5 mil

CRUSHED GARNET Blasting Speed 

Dust Factor: High

Recyclability 

As its name suggests, Crushed Garnet is a manufactured, rather than a natural, abrasive. In its original state, it is bound to other rock materials (such as granite) and must be crushed to separate it. The effect of the crushing puts microscopic fracture lines in the particles, which makes them break apart when blasting. This creates a dusty blast, and means that the recyclability of this abrasive is negligible. • Available blends are 12/20, 20/40, and 30/60 mesh • Comes in 55 lb bags or 2000 lb drums • Profile range 2 - 4.5 mil

HORNET Dust Factor: High

Blasting Speed 

Recyclability 

Hornet is a unique abrasive, being a mix of Hornblend and Garnet. Hornblend is a naturally occuring mineral which is found in all hardrock garnet deposits. Hornblend shares many similar properties to garnet in density and specific grafity. However you will find that hornblend is a dustier then pure garnet itself and not recyclable. • Available Grades 12/20#, 20/40#, 30/60# • Comes in 55 lb bags or 2000 lb drums • Profile range 2 - 4.5 mil

COAL SLAG Dust Factor: High

Blasting Speed 

Recyclability 

Coal slag is a glass matrix alumina-silicate which is produced as a by-product of coal burning power plants. As the coal burns, the residual ash (slag) becomes molten. When this slag is cooled, it vitrifies into a glassy, abrasive material, which is then crushed to produce blast media. A wide range of mesh sizes are available, with some being capable of removing very thick or elastomeric coatings. While the low initial cost of this material makes it a popular choice, there are important points to consider before selecting it. • Very dusty blast due to the crushing process used to manufacture it • It has elevated Heavy Metal content. Need to ensure that this abrasive is not prohibited for the specific job-site • Low recyclability versus other media types means more abrasive is needed • Less aggressive than other media types, which means more operator time is needed to do the same amount of work • Total job cost using Coal Slag is typically higher than that of other abrasives when factoring in the higher labor costs needed due to slower blasting, the greater amount of abrasive needed, and the higher disposal costs incurred.

COPPER SLAG / NICKEL SLAG Dust Factor: High

Blasting Speed 

Recyclability 

Metallic slags are produced from the by-products of the refining process. Similar to Coal Slag, the molten slag is rapidly cooled and the resulting material is crushed and screened. While metallic slags are slightly harder than coal slag, their performance and inherent issues are basically the same. Metallic slags are primarily used in the geographic regions where their base metals are refined.

STAUROLITE Blasting Speed 

Dust Factor: Medium

Recyclability 

Staurolite is a mineral sand which is similar to garnet mineralogically, and has moderate levels of durability and hardness. Most Staurolite comes from Florida and Western Australia as a by-product of the zircon mining process. • Only comes in one sizing range which results in higher consumption than abrasive that is the ideal mesh for the application • Low recyclability versus other media types means more abrasive is needed • Dusty blast as compared to other abrasives • Can be used for removal of mill scale and light rust • Can achieve a profile range of 1.0 – 2.0 mils

CRUSHED GLASS Dust Factor: Medium

Blasting Speed 

Recyclability 

Crushed Glass is a sourced from scrap glass containers. The containers are crushed and the glass is then classified into various mesh sizes. As a rule, glass is softer and more friable than most abrasive blasting media. Being crushed, it is angular in shape and is available in larger sizes. It is mostly used for blasting very thick or elastomeric coatings. • Health warning – the glass is highly friable and particles are a physical irritant. May cause irritation to skin, eyes, nose, and throat. • Non-recyclable • Profile range from 2-3.5

ALUMINUM OXIDE Blasting Speed 

Dust Factor: Low

Recyclability 

Aluminium Oxide is a manufactured abrasive, specifically designed for sharpness and hardness. It is available in different grades of purity, where the brown version is for general industrial usage, and the white version can be used in sanitary applications. The sharpness and hardness of this abrasive will leave a very pronounced profile. • Often used for surface preparation prior to plating, metal spraying or ceramic coating, and can be used both on both steel as well as on aluminium or non-ferrous alloys • Available in sizes 10, 12, 14, 16, 20, 24, 30, 36, 46, 60, 80, 100, 120, 150, 180, 220 and 240 mesh • Profile varies depending on size of particle • Aluminium oxide recycles well and its higher initial cost can be offset by containing and recycling it

CHILLED IRON GRIT Blasting Speed 

Dust Factor: Low

Recyclability 

A recycled product manufactured from of scrap iron. This scrap is melted down, an assay is taken while it is in the molten state, and any necessary mineral and chemicals are added before cooling. The molten iron is then sprayed into a quenching bath to create iron shot, which is then tempered, crushed, screened, graded and packed. Chilled iron is hardest of the three most commonly used metallic abrasives. This means that while it breaks down slightly faster than steel grit or shot, it remains sharp as it breaks down, providing rapid blasting and consistent profile. • Recycles up to 200 times • Used in air blast rooms where a deep and consistent profile is required G05 (0.12 - 0.3mm), G07 (0.18 0.42mm), G12 (0.3 – 0.7mm) • Wide range of mesh sizes available • Comes in 55 lb bags or 2000 lb drums

STEEL GRIT Dust Factor: Low

Blasting Speed 

Recyclability 

Steel grit is made using a similar process to chilled iron grit, only that steel is used as the base stock. Metallurgically, the difference between iron and steel is that steel has had oxygen blown into it to reduce the carbon to less than 1%, versus the 5% carbon level of iron. This lower level of carbon makes steel more malleable. While this is an advantage for manufacturing items of steel, it is a disadvantage when used for surface preparation because steel grit loses its sharp edges over time. • Very high recyclability - up to 1000 cycles • Low dusting • Profile diminishes with use, due to sharp edges becoming rounded • Wide range of mesh sizes available • Comes in 55 lb bags or 2000 lb drums

STEEL SHOT Dust Factor: Low

Blasting Speed 

Recyclability 

Steel shot is uncrushed steel grit. Due to its shape, it is the longest lasting of all the common metallic abrasives, however its round shape reduces its effectiveness in removing heavy corrosion and existing coatings. Steel shot is popular in airless wheel machines, in part because it is less destructive to the machine than other abrasive types. • Recycles up to 1000 cycles • Used in wheel machines for shot peening and cleaning applications • Wide range of mesh sizes available • Comes in 55 lb bags or 2000 lb drums

SODIUM BICARBONATE Blasting Speed 

Dust Factor: Medium

Recyclability

Sodium bicarbonate is an industrial version of household baking soda, differing only in that flow agents are added. It is also available with grades that have had a small amount of other abrasives added to it. The most common application for Sodium Bicarbonate is as a degreaser or for paint removal on a soft substrate. • Available in many different formulations – for different applications • Ideal for graffiti removal, cleaning of brickwork, cleaning automobiles and very thin coatings • Can be used on operating machinery, will not damage glass or rubber

CORN COB Blasting Speed 

Dust Factor: Low

Recyclability 

Corn Cob Abrasive is a low-density granular product made from the hard woody ring of a corn cob. This organic product is a screened, non-toxic media, and can be used both as an absorbent and abrasive. Corn Cob abrasive is used to de-burr, burnish, de-flash and polish a wide variety of products. • Ideal for deburring and polishing, often used to remove mold, smoke and fire damage • Available blends are 10/14, 14/20, 20/40, and 30/60 mesh • Can be used on operating machinery, will not damage glass or rubber • Comes in 50 lb bags
