The grind setting determines how finely or coarsely the coffee beans are ground. This affects the flow-through time of the water, the so-called extraction time. If the coffee is coarsely ground the water will flow through more quickly than with the same coffee at a finer grind setting. A longer extraction time results in more flavours being ...
In addition to the type of grinder, the quality of your grinder also matters:. Cheaper grinders tend to produce inconsistent particle sizes.Poor-quality burrs also heat up quickly and even alter the flavor profile of your beans.

Grinding operation quality indices mainly include four aspects. (1) Grinding fineness, which is the percentage of the ore particles less than pecified size after being grounded and discharged. (2) Mill operation rate, which is the percentage of the actual working time of the mill over the calendar time of the same period.
Major tin-producing countries include China, Indonesia, Brazil, and Malaysia. The United States also has some tin mining operations, although it mostly relies on imports to meet its demand. Techniques used in tin mining include both open-pit and underground mining. The method chosen often depends on the ore's depth and the surrounding environment.
