Copper slag for paint removal

Old Painting Removing Copper Slag sand blasting machine is mostly used to remove paint, thick dust, and rust from large machinery and tanks. Blast cleaning of steel and stone, surfaces, removal of mill scale, corrosion, old paint, and filth are all possible with copper slag abrasive. Copper slag, a by-product of copper smelting, is commonly utilised as an abrasive material in dry abrasive shot blasting machine to remove rust, old coatings, and other impurities. Impurities turn into slag, which floats on top of the molten metal during the smelting process. Copper slag quenched in water forms angular granules, which can be thrown away or used as described below. They have the potential to emit fatal amounts of carbon monoxide into the atmosphere.

Some heavy metals may be leached into the environment via copper slag. Open-pit mining is used to extract copper slag, which involves digging a succession of stepped benches deeper and deeper into the earth over time. Boring machinery drills holes into the hard rock to extract the ore, and explosives are placed into the drill holes to blast and break the rock.

Copper slag's chemical composition varies depending on the ore source and copper slag manufacturing technique, but it typically contains iron grit, silicon carbide, aluminium oxide, and calcium oxides in the proportions FeO: 30–40%, SiO2: 35–40%, Al2O3: 0–10%, and CaO: 0–10%. In India, we produce copper slag at a low or affordable price.

Air-cooled copper slag is black in color and has a glassy appearance. Granulated copper slag has a lower specific gravity and higher absorption than air-cooled copper slag because it is more vesicular and porous. Copper slag's specific gravity varies with its iron grit content in general.

• Appearance: Black and glassy in
• Sp gravity: 2.8–3.8
• Absorption, %: 0.13
