Perform regularly scheduled sampling and analyses as established by the laboratory, which include but are not limited to, the following tests: CO2 analysis by Eltra, fineness of coal, raw meal, kiln feed, and cement; coal ash percentage, x-ray analysis of raw materials, raw meal, kiln feed, clinker, cement, and other process samples by fused bead and/or pressed pellet; free lime of clinker and cement, loss on ignition of tower meal sample and cement. Monitor and change process/quality parameters (i.e. separator speed, weigh feeder settings, etc.) to keep raw meal, kiln feed, clinker, and cement within the aims established by the Quality Manager, as needed.
