Sand Sillica and Gravel

Sand Sillica and GravelSand and gravel quarrying is a major industry in the UK, the products are used in a wide variety of industries from glass making to building materials.

Typically the raw product goes through many stages of treatment such as crushing, pre-screening, primary / secondary density separation, drying, washing, bleaching. Flowrox abrasion resistant pump and valves are ideal for isolation and control of these processes.

As part of some sand, silica and gravel operations, the material undergoes washing and treatment using aggressive chemicals such as Sulphuric acid.

Sand Sillica and GravelIn this environment standard isolation valves would deteriorate quickly leading to plant failure. Flowrox non-metallic PVEG range are constructed in chemical resistant Polyamide.

Primary and secondary density separators using pneumatic actuated pinch valves to control the flow through the system using signals from instrumentation in theĀ  separator silo.

Silica Sand deposits are particularly difficult material to handle as they have unique has very distinct characteristics of size shape chemical composition requiring individual attention to detail.

Sand Sillica and GravelIndustrial grades of silica sand have a high content of silica (up to 99%) normally in the form of quartz, the most common crystalline form of Silicon Oxide.

Silica sand is produced from loosely consolidated deposits and from weakly cemented sandstones.

Silica is hard, chemically inert and has a high melting point, essential for many industries.
