Fine vs. coarse: Which should your grinds be? It depends, as Valerie says each brewing method requires a different grind size. "For French press, pour over, and cold brew, it's better to use coarse grind than fine grind," she suggests, explaining, "This is because these brewing methods require water to be in contact with the grind longer, …

1. Introduction1.1. Background. With the continual depletion of high grade simple ore bodies, more complex, finely disseminated ore bodies are being processed, which has led to an increase in the prevalence of fine grinding (Sinnott et al., 2006).This has been evident in the platinum group element (PGE) industry in South Africa, where …

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …

Fine grinding, and later polishing, has as a major goal to smooth that surface through a series of successive refinements. The criteria for switching grits, therefore, is: Criteria: You want to grind with your current grit until you have eliminated all the larger pits from the previous grit. For example, after hogging out with #60, you want to ...

Espresso: Requires a fine grind to achieve the characteristic rich crema and concentrated flavor. The fine grind offers more resistance to the water, extracting more flavor in a short amount of time. Pour-Over and Drip Coffee: Medium grind is ideal as it balances extraction and flow rate, producing a smooth and flavorful cup.

theory". Bond's model is most commonly used to describe primary and secondary grinding to product sizes above, for example, 100 µm. Operators sometimes use Bond's equation to describe grinding in situations where it is not appropriate, such as fine grinding below 50 µm. Using an alternative model would be a better choice in this situation.
