The original stoners were density separators designed to remove only stones from food products. With exceptional improvements to the destining concept, the LMC Roca Stoners were developed to remove the heaviest and most dense foreign materials from dry, flowable products. Glass and metals, as well as stones and dirt balls, are prime examples of everyday contamination. The Roca efficiently removes such contaminates from the product flows.
