UG-Mat Kiln Dusts | Recycled Materials Resource Center

Kiln dusts are fine by-products of Portland cement and lime high-temperature rotary kiln production operations that are captured in the air pollution control dust collection system (e.g., cyclones, electrostatic precipitators, and baghouses). Cement kiln dust (CKD) is a fine powdery material similar in appearance to Portland cement.
