Thermo Electron Corporation's GammaMetrics CBX is a Prompt Gamma Neutron Activation Analysis (PGNAA) system designed to integrate into an existing conveyor belt line and analyze, in real-time, the composition of raw materials being transported by the conveyor belt. The system analyzes the entire material stream and eliminates errors and the costs associated with material sampling. The Gamma-Metrics CBX brings unprecedented accuracy, reliability and ease of installation to the cement industry for raw material analysis and control.

A new and flexible modular design ensures a perfect fit for any conveyor belt or material size, thereby minimizing installation costs. Each Gamma-Metrics CBX is custom fit and optimized for the application in which it will be installed. Applications Gamma-Metrics CBX systems are typically used in the following applications at cement plants throughout the world: · Pre-blending stockpile control · Raw mix proportioning control · Material sorting

Analyze · Detect · Measure · ControlTM

Pre-Blending Stockpile Applications One of the most popular uses of the Gamma-Metrics CBX is controlling stockpile chemistry to meet quality targets, thus ensuring smooth kiln operation and providing flexibility in quarry operations. Whether the stockpile is longitudinal or circular, the Gamma-Metrics CBX allows the cement producer to achieve consistent composition, with minimal variations within and between piles. Raw Mix Proportioning Applications Kiln efficiency demands chemical uniformity in kiln feed, and feed uniformity comes from precise raw mix proportioning. Located downstream of the last raw mix component addition, a Gamma-Metrics CBX analyzing system provides the precise control needed to minimize raw mix variability, reduce raw material costs, and satisfy multiple QC targets.

The Gamma-Metrics CBX: Advancing the State-of-the-art The Gamma-Metrics CBX represents the most significant advance in cross-belt analysis since the company unveiled its initial product of this type in 1993. The user now looks forward to several unprecedented features: · Elimination of the requirement to install a sunshield or building to protect the analyzer from the elements · New design for supporting the analyzer to minimize structural support costs · Streamlined shielding to reduce complications from rerouting the return belt · State-of-the-art digital signal processor · New MVIA analysis methodology · New modular designed reference standards obviate the need for a crane · Single source and detector access (either side) Designed for peak performance and lower installation costs, this new millennium system sets a standard in online analysis.

Easily Integrates into the Conveyor Line The design of the Gamma-Metrics CBX system is such that its steel framework fits cleanly into a conveyor belt line with few modifications. The framework aligns with the "C" channels on which the conveyor line is supported. Existing steelwork and catwalks around the conveyor are generally not adversely affected. As an option, the user can choose to supply the steel assembly supports. Clearance requirements between the delivery and return strand of the conveyor are minimized so that bend pulleys that clear the lower part of the system are typically not required. In addition, the Gamma-Metrics CBX is uniquely configurable to identically match conveyor idler configurations, thereby ensuring a low stress transition from the idlers to the analyzer. This results in minimum wear of the belt and slider bed. Analysis Zone Configuration -- Tunnel Height, Width and Detector Position · System accommodates all material profiles and processes · Width and height optimized per application · Analysis zone geometry optimized to specific application · Adjustable detector positioning allows optimization to specific application MVIA The Gamma-Metrics CBX analyzer employs a unique and proprietary analysis methodology called Multi Variable Independent Analysis (MVIA). Thermo Electron's Gamma-Metrics CBX system is the only online analyzer in the industry to employ this advanced technology. MVIA utilizes a single calibration and provides accurate and robust analyses as process and material conditions vary (e.g. belt loading/production rate, moisture level, material type, etc.) Information Exchange and PC Interfaces The integration of a Gamma-Metrics CBX online analyzer into a cement production line generally requires a communication interface with a plant control network. The Gamma-Metrics CBX is extremely flexible in this regard and is compatible with most major communication protocols. The most popular protocol in use today is OPC. The system configures easily as either an OPC Server or an OPC Client.

Process Control Stockpile Control is accomplished either automatically or with a person in the loop (manually). In either case, the analyzer tracks the chemistry of the stockpile compared to the target chemistry and determines the preferred proportions of the source raw materials. Thermo has solutions for both longitudinal and circular stockpiles. Raw mix proportioning Control is usually accomplished automatically with the system's analysis triggering proportioning changes as frequently as each minute. Software accounts for varying time delays from the feeders to the analyzer and can accommodate multiple raw mix sources and control parameters. The control algorithm utilizes material cost minimization and allows the user to define priorities among the control parameters. Analyzer Components The Gamma-Metrics CBX analyzer system consists of four major subassemblies: Analyzer Assembly A unique modular assembly easily mounts onto a conveyor belt line and contains the detection and measurement mechanics of the system. Electronics Enclosure Advance high-speed digital electronics control, process, monitor and exchange information between the analyzer assembly and the Operator Console.

Operator Console The Operator Console (OpCon) is Thermo Electron's user interface for the GammaMetrics CBX system. The OpCon utilizes Thermo's standard Base Cement software package that provides analysis data on minute-by-minute, rolling average and interval basis; product tracking capabilities; extensive graphic functionality; alarms; and the ability to transfer data to control systems over an OPC link or by .csv spreadsheet files. Optionally, the OpCon can be loaded with process control software that allows either automatic or manual control of pre-blending stockpiles or raw mix proportioning circuits. Each OpCon has the capability for remote connection via a telephone line or the internet for troubleshooting and minor repairs. Reference Standards Unique modular reference standards are used to qualify and monitor the system's performance.
