Fine - Smoother to the touch, a little finer than granular sugar or table salt. Extra fine - Finer than sugar, but not quite powdered. Grains should still be discernable to the touch. Turkish - Powdered, like flour. Most inexpensive (blade) grinders will be unable to grind this finely.
One of the economic factors of grinding is the wear of the grinding media.This is dependent upon the material used in its manufacture, method of manufacture, size of media, diameter of mill, speed of mill, pulp level maintained in the mill, rate of feed, density of pulp maintained, shape of the liner surface, nature of the feed, and the problem of corrosion.
Fine grinding of silicon wafers requires high predictability and consistency, which requires the grinding wheel to possess self-dressing ability, i.e., after initial truing, the wheel should not need any periodic dressing by external means. In other words, there should be "a perfect equilibrium
motor is required to establish the grinding rate. Motor power should be measured using corrected power. Monitoring mill motor amperage is not an accurate method. As the grinding media wears fine enough to be carried out by the uprising velocity in the mill, the total …
Apr 30, 2001· The rate of grinding based on the specific surface increase per unit time had been dealt with in comparison with fine and ultrafine grinding mechanisms, using balls as grinding media in the previous paper . On the other side, the particle size distribution of the finished product is also important, as it influences the properties of final products.

Jul 03, 2018· This grind is generally used for espresso and Moka pots. When preparing fine grind coffee, be sure to work in short pulses. You want to give your burr grinder the chance to manually process all surfaces of the coffee. If you leave the grinder on to chew away at it, the grinding process becomes a battering process.
This will allow for the best extraction and flow rate will brewing the coffee. If the water goes through quickly, your grind is too coarse. If it seems to plug up the flow of water, your grind is too fine. Pour-Over/V60. There is little difference between the desired grind of a Chemex and a pour-over.
He found that fine grinding was well established for such high-value manufactured products as printer inks, pharmaceuticals, paint pigments and chocolate. Early IsaMill development work. MIM decided to work with Netzsch, which was a pioneer in the fine grinding field, and still a leader.
A higher extraction rate means less contact time is required, so you need to grind your coffee more coarse. A fine coffee grind can reduce the flow rate of water which in turn increases the contact time. If the grind is too fine or the contact time is too high, it will result in a bitter tasting over-extracted brew.

Figure 1 shows the relative rates of fermentation for various corn processing methods. Fine grinding corn should be avoided in beef cattle diets because fine-ground corn ferments quickly in the rumen. When feeding high levels of finely ground corn, digestive disturbances, acidosis and founder can occur.
