![]() If you let me know where you live, I can recommend laboratories that you can use who have the correct geometry.ĭISCLAIMER: Material presented on the 911METALLURGIST.COM FORUMS is intended for information purposes only and does not constitute advice. There are laboratories who claim to have a "rod mill work index" apparatus, but they use a smooth liner which is wrong and Bond's equations are not calibrated to that liner geometry. The only thing to be careful of is that the laboratory uses a Bond rod mill with a wave-type liner. If your circuit is a rod mill and ball mill circuit, you will be much better off using a Bond analysis rather than SMC. I also see software that does these sorts of calculations using Bond or SMC/Mi equations ($3k to $5k per year subscription rates). I describe the technique in the short courses that I teach, but it is not something I can describe in an email. To determine the energy for the individual components of the circuit is more difficult, and I use a method that Morrell dislikes to distribute energy between stages using a transfer size. ![]() That equation describes the total circuit energy. With the SMC and ball mill work index tests, Morrell claims you can determine the total specific energy from the primary crusher to the hydrocyclone overflow, and with minor changes described in his example you can use it for any type of grinding circuit. The equation is in two parts, and you need a Bond ball mill work index determination to complete the second part. If you look at the Appendix of your SMC test report, you will see a calculation example for determining the energy to grind from a feed size (F80) to a product size (P80). There is another method using Bond-type testing that I normally prefer, but I do use SMC in my work. The SMC test is one way that you can "benchmark" an operating mill against a theoretical power consumption for a "typical" grinding circuit. These results highlight a new era in which strict coherence and interferometry are no longer prerequisites for quantitative phase imaging and diffraction tomography, paving the way toward new generation label-free three-dimensional microscopy, with applications in all branches of biomedicine.I conferred with my friend at and he says the short answer is yes. On the other hand, it attempts to give an overview of recent developments in this field. It should serve as a self-contained introduction to TIE for readers with little or no knowledge of TIE. In this tutorial, we give an overview of the basic principle, research fields, and representative applications of TIE, focus particularly on optical imaging, metrology, and microscopy. ![]() Despite the insufficiency for interferometry, TIE is applicable under partially coherent illuminations (like the Köhler’s illumination in a conventional microscope), permitting optimum spatial resolution, higher signal-to-noise ratio, and better image quality. On a different note, as one of the most well-known phase retrieval approaches, the transport of intensity equation (TIE) provides a new non-interferometric way to access quantitative phase information through intensity only measurement. ![]() Indeed, conventional quantitative phase imaging and phase measurement techniques generally rely on the superposition of two beams with a high degree of coherence: complex interferometric configurations, stringent requirements on the environmental stabilities, and associated laser speckle noise severely limit their applications in optical imaging and microscopy. When it comes to “phase measurement” or “quantitative phase imaging”, many people will automatically connect them with “laser” and “interferometry”.
