\"CanOnline cement analyzers<\/a> continuously measure the elemental composition of the entire raw material stream, in real time, being carried on a conveyor belt. The system provides an elemental analysis of the raw materials used in the cement production process<\/a>. Continual monitoring and control of mining operations, stockpile blending and raw material proportioning helps producers optimize quarry lifetime, reduce waste, ensure quality product and minimize energy usage.<\/p>\n

Reducing raw material chemistry variation is one of the primary tenents for installing an online cement analyzer.\u00a0 Other control parameters such as C3S, C2S, C3A, C4AF, etc. can also be used as control parameters and as well, individual oxides can be also used if desired.\u00a0 Within the answer to the question \u201cCan an online analyzer help reduce energy consumption of a cement plant\u201d some foundational information can be found that describes how an online analyzer coupled with automated high frequency control can help reduce process variability.\u00a0 Also, for additional information, it may be interesting to read a case study<\/a> of such an online analyzer project that was undertaken with the goal to decrease the standard deviation of the modulus in the production of raw meal. It was found that the online analyzer eliminated the errors that occurred from sampling, since all the material that passed through the belt was analyzed by PGNAA technology.<\/p>\n

Prompt gamma neutron activation analysis<\/a> (PGNAA) and pulsed fast thermal neutron activation (PFTNA) are non-contact, non-destructive analytical techniques used in online analysis systems to determine the elemental composition of bulk raw materials. Both of these techniques are known collectively as neutron activation analysis and function by bombarding materials with neutrons.<\/p>\n

The neutrons interact with elements in the materials, which then emit secondary, prompt gamma rays that can be measured. Similar to X-ray fluorescence (XRF), each element emits a characteristic energy signature as it returns to a stable state.\u00a0 [You can get more details about PGNAA and PFTNA technology here<\/a>.)<\/p>\n

The analysis was performed on a real-time basis with the use of PGNAA technology.\u00a0 This eliminated errors that could occur from the time delay for sampling and sample preparation, which was almost 90 minutes.<\/p>\n

With the use of real-time analysis results from the online analyzer and the optimization parameters in the software, the standard deviation of modulus in raw meal production was decreased by 70% for LSF, 50% for SM, and 33% for AM.<\/p>\n

With the production of more homogeneous and stable raw meal, the clinker quality was also increased.\u00a0 Standard deviation of the free lime content in clinker production was decreased from .72 to 0.37, which was equal to almost 50% improvement.\u00a0\u00a0 Also, kiln operation became more stable, which is believed to have decreased kiln thermal consumption and increased the life of kiln brick lining.<\/p>\n
