Gravel & Sand

For the separation of deleterious substances, such as organic matter (wood, roots and lignite) or alkali reactive particles (opal, sandstone, chalk and flint), alljig® jigging machines are used to process gravel and/or sand in grain sizes of up to 100mm (4”) down to 0mm.

The allflux®-system is used for the separation of organic particles from sand by means of fluidized bed sorting. Simultaneous automatic »On line« or »Off line« blending of coarse and fine sand products permits customized particle size distribution products.

With the allgauss® wet high intensity magnetic separator one can increase the quality of industrial sand by reducing the content of feebly magnetic impurities.
