SandGuard™ is a revolutionary dust-inhibitor engineered to significantly reduce dusting during transfer to silos, flat storage, or on your well site. We developed SandGuard in partnership with an industry-leading chemical company utilizing their proven sand coating technology. The result is an enhanced version of our Northern White silica sand with less degradation than untreated proppants. Less degradation means less dust, even after repeated particle-to-particle contact during the multiple mechanical or pneumatic transfers over the material’s Lifecyle. To serve the industry, Superior Silica Sand can treat any proppant including 16/30, 20/40, 30/50, 40/70, and 100 mesh at production rates in excess of 600 tons per hour.
Our advanced coated technology evenly applies a minimal amount of chemical to each grain of sand, ensuring that SandGuard’s handling is identical to traditional uncoated frac sand. SandGuard looks and flows like uncoated raw frac sand with no changes to the angle of repose, handling or particle size. This means that no material handling or storage configuration will need to be changed to allow for the use of SandGuard. The operator will see no difference with SandGuard compared to raw sand with the exception that there will be no dust.
SandGuard is the only dust-inhibitor that protects workers during the entire process of getting frac sand from the mine to down the hole. At each location where sand is transferred, dust is emitted on raw sand. SandGuard not only prevents generation of additional dust during transport and transfers, but also traps any dust at the mine site. Other solutions such as the Box type system or Silo system only contain the dust. Therefore, when loading and off-loading boxes and transferring points both at the transload and well site, significant silica dust can be made airborne and expose employees to respirable crystalline silica dust.
SandGuard™ minimizes dust exposure for workers throughout the supply chain and can help meet the stringent June 2018 OSHA regulations covering respirable silica dust.
By reducing the need for bulky mechanical dust control systems and the larger well-site footprint to accommodate them, SandGuard™ increases operational efficiency and cuts costs.
Extensive field testing has shown SandGuard™ to be compatible with all of the frac fluids in use today. The product also offers low turbidity and superior handling.
During a recent trial, dust samples were taken by a 3rd party industrial hygienist to determine silica exposure at various points at the well site. These results showed that all areas were not only well below the new OSHA silica exposure limits of 0.050 mg/m3, but also below the critical action limits of 0.025 mg/m3. When silica exposures are above the action limits, operators must take some type of action at the well site to reduce the silica exposure to the employees.
