14 CEMENT AMERICAS • Spring 2017 • www.cementamericas.com FEATURE ring segments are also accurately machined to tight toler- ances for precise fit. Parts requiring drilled or tapped holes such as roller boss- es, clamping rings and dam ring segments are made of carbon steel or high strength steel. They are heat treated to provide the best combination of hardness and tough- ness for long, trouble-free service. Columbia Steel district managers and product engineers are responsive to customer requests for product improve- ment. As a vertically integrated plant, the company can easily deal with the changes in design, metallurgy, heat treatment and machining. Controlling every facet of manufacturing at one location helps us minimize lead-times and maximize quality. All Co- lumbia Steel parts are American-made and guaranteed for proper fit, performance and customer satisfaction. www.columbiasteel.com 7. Mercury Control The EPA's MACT rules for portland cement facilities mean that compliance plans for the future are evolving. You need a partner that can reliably and cost-effectively cap- ture mercury and keep you in compliance. ADA Carbon Solutions' core strategic focus is creating powdered acti- vated carbon products optimized for mercury control. Cement manufacturers have unique challenges in terms of maintaining a manageable mercury control loop while maintaining strict product quality control. Short- and long-term mercury equilibrium within the kiln system can complicate flue gas emissions management. Operational solutions with intermittent injection in conjunction with the right activated carbon product and careful monitoring may be required. ADA Carbon Solutions works with plants to identify the best product and control strategy for flue gas mercury emissions compliance under the plant's constraints. The company can help customer's solve the challenges of mercury control in difficult applications. "As your partner in emissions control, we help you evaluate your facility's near and long-term needs and help you develop a plan to cost-effectively provide the peace of mind that comes with a reliable compliance strategy," the company said. www.ada-cs.com 8. Plant Monitoring The world's largest, most innova- tive cement producers work hard to ensure product quality. Thermo Scientific instruments can help ensure product quality, improve plant profitability and operate saf- er, cleaner plants. The company provides analytical spectroscopy, online elemental analysis, emis- sions monitoring instrumentation and tools for dynamic weighing and monitoring, according to the company. Thermo Scientific, is the product brand representing the world's leading analytical instrumentation. "Regardless of plant size and age, we offer solutions to help you meet your needs. Whether your goal is improving efficiency of your existing plant, building a new plant from the ground up, expanding capacity, converting from wet to dry pro- cess or implementing a productivity solution in just one part of your plant, we can help," the company said. To keep cement operations running efficiently, safely and profitably, Thermo Scientific cross-belt online an- alyzers process upsets and increase throughput with minute-by-minute composition analysis of ores and con- centrates. Additionally, Thermo Scientific elemental and particle size analyzers for mineral beneficiation and flo- tation plants – when integrated with our sampling and analysis solutions – help increase the efficiency of the production process. Moreover, cement quality control laboratories face de- manding elemental analysis requirements to determine major and minor oxides in clinker, cement and raw mate- rials such as limestone, sand and bauxite. The preconfig- ured Thermo Scientific ARL OPTIM'X Cement Analyzer for dedicated cement applications offers a powerful solution that delivers high precision, outstanding repeatability and stability. Featuring a compact, reliable WDXRF platform, the analyzer comes with factory-installed calibration using NIST standards for clinker and cement, making it the fast- est turnkey solution available, noted the company. www.thermofisher.com 9. Improved Instrumentation Today's operations are using fewer, larger mills for com- minution. As a result, keeping these assets online and running optimally is paramount to productivity. Because of variations in ore particle size, feed rate and moisture content, it's essential to continuously monitor mills, crush- ers and screens to achieve desired performance. Further,
