How to judge the quality of garnet sand
One look at the colour
Observe whether the colour of garnet waterjet sand is pink, light red, or dark red. Beach garnets are pink in colour, iron-aluminium garnets are dark red in colour because they are rich in Fe2O3 and Al2O3, and they belong to the hardest of the garnet family, iron-aluminium garnets.
Secondly, look at the hardness
Rub your hands together to observe the degree of chalking of garnet waterjet sand. The waterjet sand of iron-aluminium garnet is selected from the hard primary ore of iron-aluminium garnet, with a hardness of 7.5-8, carefully crushed 4 times, with sharp edges and a low breakage rate.
Three discerning impurities
Take the same amount of waterjet sand from different manufacturers and put it into a mineral water bottle (half a paper cup of sand is appropriate, generally in the ratio of 1:9) filled with water, shake it, compare the turbidity of the water, and whether there are floating impurities. Rizhao's waterjet sand has been washed six times so that there is no dust or invalid fines to affect the cutting efficiency or impede the free flow of the garnet.
Four looks at the particle size distribution
New users can take a very small amount of sand on white paper and simply separate it to see if there are larger particles or too small particles. Bing Yang Garnet waterjet sand uses a scientific particle ratio, with large particles playing a cutting role and fine sand playing a grinding role, so that the processed product has a smooth cutting surface and good verticality. With 6 passes of scientific cleaning using circulating water, the dust content is extremely low and the waste sand is very easy to clean.
