Refractory clay
Žiaromat a.s. extracts clays from surface mines. The production capacity of clays exceeds 20,000 tons/year. Continuous quality controls determine the suitability of refractory and ceramic clays. We use hammer mills to grind low-hardness clays. All production processes are equipped with high-intensity electromagnets to prevent any possible contamination.
