Applications of A1 Garnet

  • What is Sand Blasting Used For?

    Abrasive blasting at high pressure is commonly used against an object to smoothen out a rough surface. Sand blasting describes the action of launching very fine components of the material at high-speed, in order to clean up or etch a surface. Shot blasting is used for blasting metal. Mobile shot blasting machines are most commonly used for blasting drums, floors or walls.

    Sandblasting is typically used for two different applications.

    • For cleaning a surface of something that has a lot of dirt attached to it which is difficult to remove through normal cleaning methods.
    • To carve or etch words or a design into glass or similar materials.

    During the process, many sizes as well as types of sandblasting equipment and supplies like abrasives, nozzles, blast cabinets, blast rooms, portable sand blaster, part washers, sponge blast and air supplied hoods are used. Considerable expertise is required to carry out this process with efficiency.

    To carry out abrasive blasting requires the use of specialized sand blasting equipment such as pressure blasters, blast cabinets and blast rooms. Dust and dirt is removed and cleaned by propelling the blast abrasives through a specially designed blast gun.

  • How Much Does It Cost?

    The cost basically depends on the size of the project. While a small home setup may be inexpensive, if you need a system for cleaning larger areas it will cost more. If you need a professional setup, you will require more complex blasting supplies which can work out rather expensive. You must ensure that sand blasting on a larger scale should always be conducted using the correct equipment. This will not compromise on safety standards, and will ensure that the area is cleaned properly and appropriately.

    A1 Garnet is the most popular and common type of garnet sand used in America, Australia and India. To get this variety of garnet sand, the sand crystals are crushed and then purified. The consistent availability and possibility of producing huge quantities easily makes this a popular choice. Garnets are used as a gemstone in India, and garnet sand has been mined here for the past 200 years. Abrasive garnet is added when it is mined for gem garnets and used as a polishing surface for glass industries.

    Maxworth's A1 Garnet abrasive is made up of natural Almandite garnet grains that are unique because of their natural hardness, durability and abrasive characteristics.

    It is a cost-effective alternative to silica sand, mineral slags and steel grits and shot as the perfect symbiosis of grain size, density and hardness/durability creates the optimum abrasive efficiency. You get the lowest abrasive consumption (kg/m2) coupled with the highest production rates (m2/hr).

    Additionally, A1 GarnetTM is recyclable up to 5 - 10 times (depending on the application) due to its superior toughness and low friability.

    As it is environmentally inert, A1 Garnet meets all Occupational Health and Safety requirements and achieves the highest benchmark of processing standards with respect to mineral purity, for chloride and free silica content.

    A1 Garnet is approved by major oil companies, shipyards and major paint manufacturers and is used as a blast cleaning abrasive in various industries around the world. It can be used for all areas of surface preparation including stainless steel, anti-magnetic steel and all specialty alloys as it is free of metallic iron.

    Special fine grades of A1 Garnet abrasive are also available for unique surface preparation applications that include aluminium, turbine blades, and fibreglass among others.

  • Higher Productivity at Lower Costs

    Garnet abrasives have the advantages of being harder, heavier and more durable than other blasting abrasives. Maxworth's range of garnet abrasives are superior because they cut faster and recycle efficiently. This significantly increases productivity while at the same time reducing consumption of the abrasive media and also lowering handling, collection and disposal costs.

  • Superior Surface Quality

    Blasting with garnet from Maxworth produces a clean surface that is almost completely free of embedments, rogue peaks and troughs. The end result is a clean substrate with a uniform surface profile - this improves both coating adhesion and durability.

  • Low Dusting, Safe to Use

    Maxworth's range of garnet abrasives poses little to no health or environmental risks as they are comprised of non-ferrous, 100% natural, inert mineral containing less than 1% free silica. Compared to other blasting media, less dust is produced - this not only improves operator visibility but also reduces cleanup costs while minimizing the impact on work areas nearby.

    Maxworth's garnet abrasives are proven to meet all current industry standards.

    The profile depends on the substrate material, coating type and thickness, and pressure at the nozzle among other factors. The appropriate grade of Maxworth`s blast media abrasive selected can be selected based on test results conducted under the actual field conditions.

  • Grades

    Maxworth offers a choice of grades to match any focusing tube and orifice for any given cutting application.

    • A1 Garnet 80 Mesh: This is the most popular waterjet cutting abrasive grade used worldwide. it delivers the optimum balance of cutting speed and precision edge.
    • A1 Garnet 50 -80 Mesh: This is suitable for high speed waterjet cutting. In some cases, it can deliver up to a 30% increase in cutting speed at reduced precision edge.
    • A1 Garnet 120 Mesh: This is used for high precision and minimum tolerance edge cutting requirements.

    The table states the correct combinations of A1 Garnet grades, to suit your particular waterjet cutting requirements.

    WaterJet Cutting Application A1 Garnet Grade
    Standard Industrial Configuration 80 Mesh
    High Speed Cutting 50-80 Mesh
    Precision Cutting 80 Mesh
    High Precision Cutting 120 Mesh

    If you need specialized sandblasting abrasive media, then Maxworth Minerals is your go-to company. Based in Australia, we are the leading supplier of blasting abrasive suppliers for commercial grade applications.

  • Abrasive Water-Jet Cutting

    A1 Garnet grains are among the toughest minerals in the world, as the material has withstood the test of time- being weathered and eroded over thousands of years! Our Garnet ranks high among the world's best waterjet abrasives in terms of speed of cutting and consumption of abrasive. There is no interruption in the cutting process and this reduces cutting time, increasing productivity and leading to outstanding performance in waterjet cutting applications.

    Quality control

    A1 waterjet garnet passes through stringent quality checks at every stage, assuring optimum efficiency at the lowest production costs. Typically, A1 garnets have been found to be harder than other alluvial garnets in the market, making it the first choice of leading waterjet cutters worldwide. The extensive processing makes sure that the garnet is of the highest quality, with accurate sizing of grains. The mineral is not polluted with dust, and ineffective grains are removed through careful screening.

    The optimal balance of grain shape, size and density results in the perfect waterjet garnet for all your requirements. We ensure that there are no oversize particles that could block focusing tubes, so that there is a steady flow through the tubes allowing continuous production.

    You can rest assured that with A1, you will always get the consistently high standards of waterjet abrasive that you can expect from Maxworth Minerals.


    Some of the benefits reported by A1 Waterjet users include:

    • Superior hardness and abrasive ability
    • Free of any toxic compounds and heavy metals
    • Quicker production times
    • Higher efficiency
    • Savings on cost
