Copper slag is a byproduct obtained during smelting and refining of copper ore rich in sulphides and oxides of iron and copper, in the course of removing iron as iron silicate. During the smelting process at 1250°C, copper liquid settles down due to higher density while copper slag remain on the surface in the segregated state. The copper slag is then collected and cooled with jets of pressurised water. The associated thermal shock creates a unique, glassy amorphous granulate. During the manufacture of the abrasive no crushing or grinding procedures are included. Therefore, the single abrasive particle is not broken up and retains its extreme hardness and tenacity which is the case for all particle sizes. Further, to obtain maximum blasting operating results, the particles are washed multiple times and carefully screened on different grain sizes. Due to its special features, copper slag is recognized for increased blasting efficiency and reaches a maximum potential in cleaning surfaces and material savings. Cleaning Efficiency particle density and velocity are the two major contributors in determining the efficiency of an abrasive material. The angularity of the copper slag grains allows the material to gain greater energy from the nozzle, resulting in extremely high velocity, whilst the particles’ high specific density delivers optimum cleaning power to the surface. Consequently, copper slag provides powerful fast cleaning and an optimum prepared surface for any coating system. Lower Consumption. In addition to its cleaning efficiency, the consumption of an abrasive also depends on its ability to remove the old coating whilst at the same time producing a satisfactory surface profile. The best surfaces are created by abrasives with a mixture of particle sizes. With copper slag, particle size distribution is optimised to ensure the best performance which means a notably lower consumption. Particle size distribution is controlled at the production facility with rigid adherence to specified grain sizes. Our company's expert technical team will be happy to assist you.
