| Naturally occurring aggregate and mineral deposits, as well as man-made industrial sands, rarely meet the specifications required of final products. These deposits often contain deleterious material such as clay, silt, twigs and other debris that can decrease the quality, efficiency and durability of the final products if not removed. Crushed sands often contain an excess of harmful fines that can throw the end product out of spec. Removing these fines and deleterious material is key to producing the high-quality aggregates and minerals that are necessary for their various end uses. This is why washing is essential for many aggregate and mineral production processes.
