Junda Advantages in Waterjet Cutting
Garnet comes in two basic forms, crushed and alluvial, the later being roughly similar to sand washed up on riversides. Our garnet for export is produced from our crystalline almandite garnet and river garnet sand. deposits. Thank to its sharp edges from crushing, this kind crushed garnet acts more like a sharp cutting tools so that it is superior to alluvial and have been shown to cut better and faster.
Sharper Edges
Due to our Junda garnet sandis crushed from almandine rock, it acts more like a sharp cutting tools and can cut faster and more efficiently than alluvial garnet.
Faster Cutting
Crushed and selected from hard rock so that Junda waterjet grade garnet produces harder and sharper edges than other waterjet abrasives. These characteristics enable our garnet more like a hard and sharp cutting tool to finish a faster cutting.
Better Edge quality
According to the cutting material and edge quality requirement, there are various special and proper waterjet grades recommended that enable a better edge quality.
Less Dusty
Junda garnet has high garnet purity and very low dust. That makes the whole cutting course more smoothly.
Choosing the Proper Mesh or Grade
Junda offers various grades to match any focusing tube and orifice for any given cutting applications. Choosing the proper mesh, or grade, for the operation is very imperative. Different mesh sizes of garnet are designed to pass through different sized nozzles and choosing the wrong grade could be stop a waterjet operation completely. If the garnet grade is too large or coarse, the granules can jam inside a tube and cause a blockage. Too fine an abrasive have a tendency to “clump” together inside the cutting head and again, have the potential to clog. Or it may inhibit the flow of garnet in the feed tube and not consistently enter the venture of water flow between the jewel and nozzle. If you are not sure which mesh or grade is proper, feel free to contact us and we would like to give you our professional suggestions.

Application
Sandblasting
Garnet sand abrasive has features of good hardness, high bulk density, heavy specific weight, good toughness and no free silica. It is widely used in aluminum profile, copper profile, precision molds, and many other fields. And it is used for sandblasting, rust removing and surface treatment in stainless steel, carbon steel, steel structure, aluminum, titanium, galvanized parts, glass, stone, wood, rubber, bridge, shipbuilding, ship repair, etc.
Water Filtration
Thanks to it heavy specific weight and stable chemical properties. Our garnet sand 20/40# can be used as the bottom media of filter bed in water filtration of chemical industry, petroleum, pharmacy, cleaning drinking water or waste. It is one of the most cost effective alternatives for water filtration beds to replace silica sand and gravel in water filtration, Especially it can be applied in beneficiation of non-ferrous metals and oil drilling mud weighting agent, because it resets the filter bed more rapidly after the filter bed is back-flushed.
Water Jet Cutting
Our garnet sand 80# has features of sub conchoidal fracture, high hardness, good toughness and sharp edges.It can form new angular edges constantly during crushing and classifying. Water jet cutting uses garnet sand as the cutting medium, relies on high-pressure water jets to water jet cut oil and gas pipelines, steel and other components, stainless steel, copper, metal, marble, stone, rubber, glass, ceramics. Also for its high speed and fluency in water jet cutting, it will not jam the cutting tool bit used on water jet cutting machine.
