OUR proven silica sand washing solutions ensures:

Guaranteed precision and maximum process efficiency – the precision of the cut points and careful attention to all material transfer points maximizes retention of in spec material and water within the circuit and ensures maximum product yield.

Removal of iron oxide and other deleterious materials – iron oxide adheres to silica particles and must be scrubbed from the surface of particles. Hengyang’s spiral classifiers use higher specific gravity to remove refractory heavy minerals and iron oxide particles from the silica sand and the CFCU removes any remaining fines.

Minimal footprint and rapid deployment – the clever integration of several processing phases throughout our modular equipment range minimizes the space required to accommodate a silica sand washing plant and reduces overall project costs through the reduction in associated works to prepare for the plant installation. While our modular design require less time to install than the traditional stick build / static plans. This ensures operations are up and running in the shortest possible time.

Minimal environmental impact – by choosing our water recycling and tailings management system you will achieve up to 95% water recycling from your wet processing plant and also significantly reduce the space required to accommodate your silica sand plant.

Hengyang undertakes a full and detailed analysis of feed material including particle size distribution (PSD) and the chemical properties of your silica sand to understand and deliver a solution that meets your requirements.

Our proven silica sand washing solutions produce a range of in spec materials including:

• Glass sand: 150-650 microns
• Ultrafine sand / silica flour: 30-150 microns
• Construction: -650 microns
• Coarse sand: 650 microns-3mm
• Oversize: +3mm
