Slag grinding removes all heavy slag quickly and effectively, using rotating brushes that work in the opposite direction of the sheet metal being fed in order to grind and basically sand down the unfinished material. These machines use a series of belts to grind and brush through even the heaviest dross accumulations.
Ground granulated blast-furnace slag, more commonly referred to as slag or slag cement, is a by-product of steel production. Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3 ), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the ...
