Artificial Aggregate Production from Fly Ash
The expanded material has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete product. The production of lightweight aggregate begins with mining or quarrying the raw material. The material is crushed with cone crushers, jaw crushers, hammer mills or pug mills and is screened for size.
