Abrasive
Abrasive steel shots, grit, garnet sand are used to make a surface clean, reusable with the help of the blasting process. Abrasives are available in various shapes, sizes and have different hardness and application areas. Steel shots are round in shape and high hardness so they are used to remove heavy rust from the components of hard metal like stainless steel, mild steel. Steel shots are expensive and can be reused easily. Shots show their working properties very well when reused many times. Abrasive grit and steel grit has sharp edges. It is used on hard metals to remove old hard paint, grease, rust, oil. Steel grit can be reused many times and shows the same results. For recycling of abrasive sand blasting machine, sand blasting cabinet, shot blasting cabinet, grit blasting cabinet, blast room system is used. Mechanical recovery systems and industrial dust collectors are used for recycling the abrasives.
Garnet sand is the best abrasive and mostly used in granite stone blasting. Abrasive garnet sand available in many sizes. To perform blasting copper slag, glass beads, plastic media aluminium oxide, etc are also good options. Which size of blasting media is used is depends upon the sand blasting nozzle. Nozzles are available in various sizes and as per the nozzle size working results of blasting vary. Now days blasting machines used in almost every industry like automobiles, railway tracks, and bridges, train bodies, food storage tanks, buildings, boilers, pipes, ships, etc. To perform blasting, sand blasting machine, sand blasting hopper, grit blasting machine, shot blasting machine is used. In some industries after blasting thermal spray coating is done for which flame spray gun and arc spray gun is used. In thermal spray, metalizing wire coating is applied on the substrate which increases component life, and no maintenance required.
