Intentional Avoidance of Quality Issues

During the extraction of oil and natural gas from shale, frac sand plays a crucial role in the oil and gas industry. However, before it can be used in fracking, it must undergo a complex mining and refining process. Maintaining the moisture content within a specific range is essential during the manufacturing process to ensure the effectiveness of the frac sand in assisting with the extraction process. After washing the sand to eliminate unwanted particles and removing excess water through settling ponds or belt presses, the sand is then moved to stockpiles for drying.

Drain tiles beneath the sand piles help in water removal and recycling to reduce environmental impact. Subsequently, the dried sand is transferred to rotary dryers for further drying, with moisture content needing to be reduced from 4-8% to 1% or less. The use of a near-infrared moisture sensor in this stage provides continuous and instant moisture measurement, enabling real-time adjustments to be made to minimize product loss.
