Companies from the most diverse segments consume significant volumes of industrial minerals and other compounds every day. If inputs do not have their technical characteristics well controlled, industrial processes become hostage to the variations presented by raw materials. In this context, periodically carrying out batch laboratory tests can be an important tool to guide receipt and relationships with suppliers. At CRC, we can guide companies in defining the most suitable laboratory tests for each situation, as well as carrying out this routine monitoring, aiming to detect unwanted variations and guarantee the constancy of the supply of raw materials. In addition to laboratory analyses, we present statistical analyses of results over time, thus facilitating decision-making based on statistical parameters.
