Coffee Particle Size and Shape Analysis

If, for instance, you are preparing an espresso or Turkish coffee, a very fine grind with grain sizes below 1 mm is required; for common drip brewed and filtered coffee particle size is below 1.5 mm and for Scandinavian, French press or American brewed coffee it is just below 3 mm. Inspired by capsule technology, the coffee industry is constantly bringing new types of coffee onto the market ...

Choosing the Right Grinding System for .

It is used for ultra-fine grinding of soft to extremely hard materials in a fluidised bed. By using an air classifier, integrated in the mill, the maximum particle size is limited and it is possible to achieve fineness in the submicron range. Significant benefits are gained by using superheated steam as a grinding medium instead of air.

Grinding (abrasive cutting) - Wikipedia

Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.) [citation needed].
