FDA Approved Limestone Mining Dealers: Industrial Processing Equipment for Regulatory Compliance

The Compliance Challenge in Limestone Mining Operations

Your limestone processing facility faces three critical operational pressures: maintaining consistent particle size distribution within FDA foodgrade specifications (tipicamente 200 mesh or finer for calcium carbonate additives), managing moisture content below 0.5% to prevent microbial growth, and controlling heavy metal contamination below 10 ppm thresholds. Noncompliance with FDA 21 CFR 184.1191 standards can result in batch rejection costs averaging $47,000 por incidente, plus production downtime of 1218 hours for equipment sanitization. Are your current screening and milling systems delivering the traceability documentation required for FDA audits? Can your material handling equipment prevent crosscontamination between industrial and foodgrade limestone streams?
