Fly Ash Separation Technology and its Potential Applications
separation process technologies are commercially available to separating fine particle size by screen mesh, cyclone, or milling. Generally, the lowest particle size is about 10 µm by the cyclone separation and 25 µm (500 mesh) by the mesh method. The milling requires significant energy to grind down to 13 µm or submicron sizes. Consistently
