Elemental Analyzer (EA) I. Product Overview Elemental Analyzer (EA) features one cross-belt type online detecting device for cement materials. It is mainly used for online detection of element (compositions) contents during limestone batching, raw mix. EA is a modular structure and can be installed around a belt without the necessity to cut it. When EA operates, the belt slides through the internal supporting tank of the measuring unit and then EA measures all the materials passing by. During the whole detection process, no material is contacted and there is no influence on belt operation. When...

after entering into the photoelectric multiplier. The electric pulse is magnified by electronic signal processing parts and converted through ADC, and then recombined gamma ray energy spectrum is generated. Afterwards, the element (components) of such energy spectrum can be disclosed by microprocessor and advanced analysis software. III. Product Composition EA consists of such five parts as measuring unit, neutron source, detector, signal processing cabinet and host computer. 1. Measuring unit Measuring unit is of modular frame structure, including key parts supporting the prompt gamma neutron...

5. Host computer Host computer consists of hardware and software, mainly acquires and analyzes digital signals from signal processing cabinet, calculates the contents of element and related quality control parameters, so as to direct and control cement production. The hardware is a computer and the computer is equipped with data transmission interfaces. One interface exchanges data with the factory control system via OPC communication, and the other interface provides remote technical services via the Internet (provided by the factory). By using optimized analysis algorithm, the software can...

*Size and weight should be determined according to the application site. V. Product Characteristics Comprehensiveness: Measuring all the materials passing by, with strong representativeness; Fastness: Giving composition data once per minute; Effectiveness: Providing key parameter data for production, so as to make effective control; Stability: Complete hardware and software safeguard measures ensure stable operation of instrument; Being compared with same kind products, EA’s advantages lies in Strength • DFMC undertakes national scientific development project for neutron activation instruments •...

The material has strong ability to absorb the rays, the protective body is thick, and it is safer and more reliable  DFMC has nearly twenty years of experiences in industrial nuclear instruments development and radiation protection VI. Product Applications EA is mainly used for limestone batching and raw mix in cement plants. According to real-time raw materials information detected by the analyzer, quarry optimal dispatching control and statistics on quality and ingredients, the limestone batching can be achieved. While the raw mix control is realized by controlling the feeding volume of various...

Automatic mode Automatic mode is available under the circumstance that raw materials are stored in different storages (there are automatic feeders after storages). Automatically control the matching ratio of materials through control system to meet the quality requirements of the pre-mix pile. Fine batching mode Realize the dispatching management of mine production and equipment by utilizing GPS/BeiDou positioning and navigation technology. According to the batching target requirements, in

combination with the production plan and by automatic directing and dispatching of operating equipment in mine, the grade of raw ore is strictly controlled at crushing station; EA is used to make real-time monitoring on the batching results, and the results are fed back to the production dispatching and directing level, thus realizing accurate control on the grade of raw ores at crushing station. 2. Raw mix Used in conjunction with automatic batching software, EA can conduct process control on raw mix. EA sends current analysis result to batching software. Batching software controls feeding amount...
