Material Handling & Product Quality Enhancement

Case Study

Final Product Flowability Improvement at Frac Sand Plant

Challenge

Final product exhibited poor flowability in railcars due to residual moisture. This led to customer complaints and transport delays.

ENG Solution

ENG conducted lab testing on particle size distribution and moisture retention. A low-dose hydrophobic treatment was integrated into the final rinse process. Modifications were also made to the stacker drop height to minimize particle breakage.

Results

Moisture content reduced from 8.2% to 5.5%
No reported flowability issues in 60 days post-implementation
20% faster unloading time, operator improved handling of containers
