22 CEMENT AMERICAS • Summer 2019 • www.cementamericas.com FEATURE for process control. Accurate volume in irregularly piled materials and large vessels is possible using 3D level sens- ing technology. Software and cloud-based applications enable monitoring multiple vessels and locations from your smartphone, tablet, or PC. Inventory valuation for financial reporting can be generated with confidence. Learn about the newest solutions and how they can make your opera- tions more efficient. Wednesday, Nov. 20, 2019 Cleaning and Maintaining Silos Dennis Blauser, Marietta Silo In this presentation, attendees will learn how to economi- cally construct a storage silo; keep silos operating efficient- ly; lower or eliminate silo cleaning costs; keep silos structur- ally sound and personnel safe ; and lower silo operational costs. Marietta Silos is the largest concrete silo repair com- pany in the United States. Energy Savings and Process Optimization in Cement Production Udo Enderle, Managing Director, NETZSCH Feinmahltechnik GmbH Processing of industrial minerals and cement demands energy efficient technologies to minimize energy consump- tions for both, size reduction and material transport. During the last years several efforts were made by NETZSCH to improve the performance of its horizontal bead mill Pamir in collaboration with Hacettepe University for grinding fly ash and cement by optimizing the material transport in the mill. The solutions found in pilot scale are being discussed and more results from production by using a Pamir 1000 are presented. Optimized Kiln Operation by Keeping Kiln Shell Temperatures at Set Point with Con- trolled Water Cooling Heinz Knopfel, ARGOS Cement US and Dirk Schmidt, Director, KIMA Echtzeitsystme GmbH Increasingly powerful and sophisticated kiln-firing process conditions make it necessary to cool the kiln shell in order to protect the refractory material and the steel body from overheating and wear. Traditionally the cooling is done with high performance blowers and only a few plants in the world are actually working more or less successfully with cooling by water evaporation. In 2014, a team consisting of the VDZ and a cement manufacturer decided to conduct an experiment in measurement and control technologies. The aim was to develop an efficient cooling system with the medium of water. The goal was to determine at first how much water is needed to produce not an equivalent cooling effect as achieved with a conventional cooling fan. This pre- sentation reveals the results. Realizing Energy Savings Using A Ceramic Lined Rotary Valve In Place Of A Screw Pump Keith E. Kressley, Coperion Energy saving is becoming a more and more important top- ic in the cement industry. The air supply (screw compressor) and the material feeding device into a pneumatic conveying line are the highest energy consumers of a pneumatic convey- ing system. For many decades the screw pump was the most frequently used material-feeding system, but screw pumps require extremely high electrical power. Looking on this dis- advantage of the existing technology, Coperion has adapted the well-known technology of rotary valves for the high wear application in the cement industry. This technology saves more than 95% of power compared to the screw pump. MSHA's Enforcement Focus on Structural Integrity at Cement Operations Bill Doran, Attorney-At-Law, Ogletree Deakins As a result of high profile accidents around the country involving structural failures, MSHA has placed a greater emphasis in its inspections on evaluating the structural integrity of silos, bins, buildings and conveyors. This has had a particular impact on cement plants. These enforcement evaluations tend to follow a familiar pattern beginning with general observations and concerns by inspectors, demands for third party examination, and moving to comprehen- sive analyses by MSHA technical support engineers. These issues can be difficult to resolve and often include requests for internal documents, allegations of unwarrantable fail- ure and failure to timely abate. This presentation will dis- cuss recent cases and offer some insight into how to effec- tively navigate the pitfall that can arise. High-End MSHA Training: Surviving an Inspection Brian Bigley, Cemex This is a high level overview of the key components of an MSHA inspection, and your role as an attendee. It will serve as a quick introductory primer for people who might
