iAbrasive: How It's Made Abrasive Grains
Zhengzhou, China (PRWEB) December 10, 2014 -- According to Wikipedia, an abrasive is a material, often a mineral, that is used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. Abrasives are extremely commonplace and are used very extensively in a wide variety of industrial, domestic, and technological applications. Common uses for abrasives include grinding, polishing, buffing, honing, cutting, drilling, sharpening, lapping, and sanding.
Abrasive grains undergo heavy process in different degrees, from very superfine to very coarse. The right grit of abrasive grains is essential for finishing the job. The bauxite is blended with other minerals, then released into an electric arc furnace to heat the mix to over 3600 degrees Fahrenheit. That's hotter than an active volcano. Then a technician takes a sample for chemical analysis. If everything is right, the multi-minerals are poured into a big steel pan and transported to a cooling area. 24 hours later, the materials get hardened, and it's time to bring the ball that cracks open the hardened materials by being dropped repeatedly to break up the hardened minerals.
The next step is to inspect the grain shape. A sample is poured into a cup and then it's weighed. Higher weight means bigger density stack. A different test is to use miniscale grits. The particles are suspended in a solution that allows inspectors to count and evaluate the grits via computer. Finally, the abrasive grains are ready to be packed.
