ALLUVIAL GARNET SAND

Alluvial Garnet sand includes sea garnet sand river garnet sand.

River garnetsand is a type of garnet abrasive that has been deposited into rivers through natural weather processes. While not better than supreme garnet abrasive, river garnet abrasive is cheaper than regular garnet abrasive because it is readily available and is easier to produce. Like sea garnet, river garnet is constantly exposed to natural elements especially flow of river water and therefore has typically smaller mesh sizes and more rounded edges. River garnet also has some impurities but depending on where it is sourced, it may have lower chloride and salt content than sea garnet.

Sea garnet sand is a garnet abrasive that has eroded from rock garnet and has been carried by natural processes into seas and oceans. Because it has been consistently exposed to pounding waves, sea garnet tends to have obtuse angles, smaller sizes and rounder shapes compared to rock garnet. Also because this garnet abrasive is extracted from seas and beaches, this abrasive has a higher chloride and salt content than regular rock garnet abrasive.The main advantage is that sea garnet sand is a natural garnet from sea beach mines. It was served directly without any crushing and milling process. Since there are no cracks in the grain, it gets less dust and of heavier specific density. For waterjet cutting work, the 80 mesh alluvial garnet sand will get a smooth cutting performance. In the meantime, it won’t block nozzles and thus save time and cost.
