Copper slag is used for sand blasting machine, which is black in colour and accessible at a reasonable cost, is used for shot blasting machine. Copper slag is a waste product formed during copper smelting that is then processed into abrasive items. Copper slag which is molten quenched in cold water and it's usually made up of ferro silicates and aluminium oxide grit. The slag is fractured into coarse, angular particles during the cooling process, making it appropriate for a variety of applications. It's a low-cost expendable abrasive that's ideal for open blast cleaning and doesn't pose the same health risks as silicon carbide sand because of its low silica content.
Copper slag is very sharp, hard particles may clean quickly and have a great surface profile. Abrasive blasting media, building materials, land filling, road construction, abrasive instruments, cutting tools, tiles and glass, and roofing granules are all examples of copper slag applications. In blasting applications, replacing sand with copper slag results in a safer and cleaner dust-free environment, as well as high quality and efficiency. It slices the surface faster, resulting in fewer man-hours and a polish that is close to white metal. It gives a standard polish to the surface. To copper slag can be used to replace up to 10% of the sand in concrete by mass or weight.
Copper slag is a good substitute for sand blasting cabinet during the monsoon (rainy) season since it has similar qualities to sand. Copper slag is also utilised as a raw material for clinker, cement replacement, coarse and fine aggregates in the copper slag manufacture of cement, mortar, and concrete. Copper slag is used in road construction and structural filling. It is an excellent soil alternative for land filling. Copper slag is also less expensive than soil and contributes to environmental protection.
Copper slag in dry abrasive grit blasting cabinet, which is an expensive technique that produces substantial volumes of particulate emissions and spent material, is commonly used as an abrasive material to remove rust, old coatings, and other impurities. Copper slag is easily available in market and at the very low cost. Because of its low cost mostly people used the copper slag is effective for blasting. It is also used in sand blasting cabinet, aerospace, furniture, wood etc.
