Production programme
Micro-milled sands
The micro-milled sands – silica flour are produced by milling in a ironless environment, by classification with use of air separators. The raw material used for the production of micro-milled sands – silica flour is treated silica sand with SiO2 content above 99 %. The chemical purity, favourable particle size distribution, chemical inertia and hardness of micro-milled sands – silica flour is appreciated in the production of glass fibres, ceramic enamels, glazes, as a filler in plastics, in the production of special mortar mixtures, tile adhesives and in the foundry industry for the production of moulds. The sands are being sold in bulk or in bags, transported on trucks or wagons.
