Team leader with a passion for researching and developing testing methods for aging and material characterization, and life time predictions.

A team leader that reports directly to the Operations Manager providing process data on kilns and finish mills production.Major AccomplishmentsOptimized fuel cost preheater/precalciner through using slag at $1/ton vs. coal/coke at $30/ton achieved 80% use of slag.Assisted in optimizing Pfister rotary feeder, through adding extra blower, minimized sporadic operations due to low pressure.Measured and calculated process flows for air sweep, nuisance, and process dust collectors and develop historical data for troubleshooting purposes.Daily production and process meetings for repairs and operations of plant.Researched and trained on process operations for calculating circuit load for Sturtevant separators using both blaine and m325 methods.Assisted in daily operations of Allis Chalmers roller mill for kiln feed 260 tph, Loesche coal mill 12 tph, 2 – 12’ X 165’ kilns 150 tph, 1 – 12’ X 65’ Polysius finish mill 100 tph with Sepol separator, and 4 Fuller Finish Mills 30 tph with Sturtevant separators.Calculated plant’s total energy consumption and reduced 1500 KW through minimizing finish mill operating times.

A lab member that reports directly to the quality manager, and provide technical data on cement chemistry and ASTM standard.Major AccomplishmentsReduced amount of sampling frequency of cement by 1 hour, to allow for new testing method.Initiated placement for a new kiln clinker sampler. This reduced technician’s troubleshooting time. Improved efficiency within the lab, and eliminated down time.Implemented changes within the lab to minimize waste, improve ergonomics, and improve morale.Trained new employees on lab equipment and test procedures.Researched effects of sucrose on cement set times, eliminated waste of excess dosage to match proper set times.Researched dehydration of coal with different lab equipment. Established proper moisture offsets between different convections ovens.Reduced annual maintenance cost by 17%, by streamlining maintenance process.
