FEATURE 84 • ROCK products • August 2019 are reliable in dusty conditions. Advancements in radar technology allow sensors to track filling and emptying 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. 4:30 – 6:00 p.m. Reception on Show Floor 6:00 p.m. Exhibit Hall Closes Wednesday, Nov. 20, 2019 8:00 a.m. Exhibits Open – Morning Coffee Break on Show Floor 9:00 - 10:00 a.m. Sessions DSI and ACI as the Optimum Solutions for SO2 and Mercury Abatement Xavier d'Hubert, Senior Consultant, STM EcoSystems, Inc. Many cement plants have installed some Dry Sorbent Injec- tion (DSI) and Activated Carbon Injection (ACI) for SO2, HCl, mercury abatement. The principles and technologies are well known however many of those systems are not opti- mized or require too much maintenance, both costly for the cement plant. STM EcoSystems offers simpler but perma- nent and optimized systems, using several sorbents from hydrated lime to Trona. One key feature of those systems is the very large turn-down ratio. Many plant permits require the system to operate all the time, even when the emissions are low and the system is not needed. Even poorly designed injection lances can result in double the theoretical con- sumption; lance size (injection velocity), location, position in regards to the duct, angle in relation with the flue gas flow, number of lances are all parameters that need to be taken into consideration for an optimum system design. Energy Savings and Process Optimization in Cement Production Udo Enderle, Managing Director NETZSCH 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. 10:00 -10:30 a.m. – Morning Coffee Break on Show Floor 10:30 a.m. - Noon Sessions How to Save Thousands of Dollars on Silo Cleaning Costs Dennis Blauser, Marietta Silos 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. 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 Process Control 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. ICSE
