· It’s a game-changer in modern road maintenance and construction. Asphalt recycling involves reprocessing old asphalt into new paving material. This process includes milling or breaking up existing asphalt, combining it with additives, and rejuvenating it. Key benefits include reduced material waste, lower costs, and less environmental impact.

The old cement powder is then used instead of lime-flux in steel recycling. As the steel melts, the flux forms a slag that floats on the liquid steel, to protect it from oxygen in the air. After the recycled steel is tapped off, the liquid slag is cooled rapidly in air, and ground up into a powder which is virtually identical to the clinker which is the basis of new Portland

The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is “calcined” into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
