Sand Mixing Control System

The operational process requires automatic, uniform mixing of liquids, proppants, and additives according to the prescribed formulation; it also enables the delivery of sand‑carrying fluids with varying sand ratios, densities, and flow rates, thereby achieving precise control over the proportioning of all raw materials. The system is equipped with both local and remote control terminals, meeting the demands of onshore and offshore fracturing operations.
Sand Mixing Control System

The operational process requirements dictate that, according to the preset formulation ratios, the system automatically and uniformly mixes fluids with proppants and additives, delivers sand‑carrying fluids of varying sand concentrations, densities, and flow rates, and achieves precise control over the proportioning of all raw materials. The system is equipped with both local and remote control terminals, meeting the demands of onshore and offshore fracturing operations.
