Product Description

Product Description

Garnet abrasive sand is a naturally occurring silicate mineral deposit. The harder species of abrasive garnet like almandine are used for abrasive purposes because it has a hardness on the Mohs scale of about 7 to 7.5 and provides the perfect balancee between  cutting speed and superior edge quality.

Garnet sand is washed, processed, and screened to the necessary abrasive grade for use as an abrasive media in industry of water jet cutting,sand blasting,shot blasting.

Garnet abrasive Application

• Garnet media can be used in all types of waterjet cutting machines.
• Garnet abrasive sand allows uninterrupted production without downtime for optimum efficiency and low production costs.
• Sand Blasting Machine and Shot Blasting Machine for finishing, deburring.
• Garnet sand provides the perfect balance between cutting speed and edge quality.
• High-quality alluvial garnet sand does not contain any fracture lines that can weaken the grain.
• Equipment wear and tear are reduced resulting in longer service life.
• Granet media blasting sand Offers high production rates and superior edge quality.
• Tightly graded to minimize downtime and maximize production. 
• Cold cutting - no heat-affected zones, no hardening.
• Perforates most materials without starting holes.
• Cuts virtually any material.
• Net-shape or near-net-shape parts (no secondary processing required in many applications). 

Chemsize are focused on our quality products and customer satisfaction. We provide abrasive Garnet Sand, Almandine Garnet Sand, Water Filtration Garnet, Garnet 12-24 Mesh, Garnet 20-40 Mesh, Garnet 30/60, Garnet 80 Mesh at low price at minimum delivery time.

What Is Garnet?  Garnet is a sandblasting mineral, derived from either Almandite or Andradite deposits.  Almandite garnet is further separated by being either Hard Rock or Alluvial.  It is great for both wet and dry sandblasting applications.  Garnet is a industrial gemstone that creates a profile virtually free of embedment, which makes it excellent for coating adhesion, as well as applications where low or no transfer of grit into the substrate can be tolerated.  We offer Almandite garnet, as well as Andradite type garnets.

The simplest way to describe garnet would be "Clean & Fast".

Benefits:

• High hardness.  Garnet will last a long time, making it a very cost effective sandblasting abrasive.  Mohs Hardness is 7 to 8 depending on the type ..
• It can recycle a number of times, depending on your grit size (generally you can obtain recycle garnet twice, perhaps more when starting with a coarse grade).
• Environmentally Friendy!  It is thus often used to blast stuctures residing over or next to bodies of water where contamination by the blasting media itself is a concern.
• Garnet is safe and non toxic with very low free silica levels (generally less than 1%). 
• Low Dusting.  Garnet is a fast and clean blast media.  Often referred to as "Poor Man's Aluminum Oxide"
• Excellent for coating prep, surface prep use.  Garnet will leave a profile that is almost free from embedment, troughs, and peaks.
• Multiple Shipping Points around the country.  Get a Quote Now.
• Color: Depends.  Pink, Red/Brown, Grey/Brown 

Excellent For:

• Tanks and other confined spaces where use of a low dusting abrasive is necessary.
• Dry docks, Bridges, Shipyards - a great abrasive to use where water contamination is a concern.
• Aluminum and Fiberglass surfaces
• Hangar decks
• Powdercoating, denim blasting
• Industrial Painting

WATERJET GARNET:  

We have two types of waterjet garnet.  The first is Galaxy Garnet which is a hard rock Almandite garnet.  This is a premium garnet for waterjet use, and is available in an 80 grit.  

Second, we off an Andradite Garnet for waterjet use that has been cleaned and re-screened to Waterjet Specs and gone through several passes on a magnetic separation device to remove most tramp minerals.   This garnet has a slightly lower density and lower hardness rating than the permium Galaxy Garnet.  It will also have a hint of a trace mineral called Wollastonite (a tramp mineral) that we are unable to completely remove with magnetic separators.  It will thus be slightly more dusty, about 5% more dusty than Indian waterjet garnet, and it is also slightly less hard (7.0-7.5 on the Mohs scale).  If you were using our premium Galaxy Garnet you will notice a difference when switching to this less premium media.  Mainly you will need to change your filters more often (about twice as often) due to the Wollastonite.  There should be no change to cutting speed.  Benefits of this media include availability and price - we have huge quantities available (for decades to come), at a great price, with virtually no chlorides (Indian garnet contains chlorides), same gradation as Indian Garnet, and are now able to offer this media in a 20/40, 30/60, as well as 80X grit.  The 80X is used for waterjet use and the coarser grades are used in regular sandblasting applications, and will be noticeably less dusty than regular garnet due to the special processing it goes through (same processing as the 80X for waterjet use).   

Coverage Notes For Regular Sandblasters Using 30/60 and 20/40:  Paint contractors are loving these coarser "waterjet" grades for regular sandblasting use.  Surfaces are blasting exceptionally clean, free of debri, and they report using 1/3 to 1/2 LESS than regular sandblasting garnet would require.  So even though the price is higher for our "Waterjet grade" garnet, project costs are less due to less media consumption, and labor costs.  Brown / Grey in color.

We also offer a permium Almandite / Alluvial garnet which is pink in color 

 

Re Coverage Estimate:  Most people using our Garnet use 30-40% less garnet than utility products like glass or slag. It's more dense so it works harder.

Garnet Sizing and Profile Information:

16mesh - Very Coarse.  ideal for blast rooms due to the number of times you can recycle.  Provides a 3-4 mil profile on blasting steel, bridges, ships and tanks.

20/40mesh - Medium Coarse.  

36mesh - Coarse.   Produces a 2 - 3 mil profile on steel surfaces.  Generally used for thick coatings, marine fouling, and rust.  Sandblast grade only.

30/60mesh Medium.  Produces a 2.0 - 3 mil profile on steel surfaces.  Considered to be an overall workhorse grade for new steel and maintenance for coatings up to 20 mils.

50 Mesh.  Sandblast grade only.

80 Mesh - Fine.  Produces a 1.5 - 2.0 profile on steel surfaces.  Great for aluminum and other sensitive substrates.  Also perfect for marine aluminum applications, and hydro blast cleaning operations.  Also available in Waterjet Grade!
