While gravel and sand can be extracted through wet and dry mining alike, they often feature natural impurities or problematic compositions. This means they must be optimally processed in advance, with coarse sieving being followed by material sorting in order to remove unwanted components. As base materials, gravel and sand are used in a variety of construction applications such as the production of concrete. They also fulfil a wide range of uses as industrial minerals.

Gravel and sand: optimum processing with allmineral

When processing gravel and sand, it is important to separate the minerals from harmful components. The flexible deployment of various wet processing machines can serve to meet your requirements. allmineral machines are ideally equipped for all conventional grain diameters and enable flawless processing of even the coarsest fractions.  They are also fantastically user-friendly and remarkably durable.

alljig® jigs

alljig® jigs are used with all grain sizes for the purpose of separating out harmful organic material (wood, coal, etc.) and components that react with alkalis (such as opaline sandstone, chalk and flint).

The allflux® procedure

In sand applications, the allflux® fluidised bed procedure separates out organic components, produces sand fractions through precision classification, and performs customised mixing of these fractions both online and offline.

Flexible and powerful – allgauss® plants

The allgauss® high-intensity magnetic separator can considerably improve the quality of industrial sands by separating out unwanted magnetic impurities.
