Jan 15, 2001· In this work, it is considered that the ultrafine grinding of quartz has been achieved by the addition of alcohol and glycol. The mean specific surface diameter of quartz is around μm at the specific surface area of 11 000 m 2 /kg assuming ground quartz particles to be spheres. Fig. 3 shows the scanning electron micrographs of quartz obtained by the grinding with methanol additive for the ...
Good product for this money. We make our coffee in a Turkish cezve so we need thin ground powder. The grinder makes full cup in less than 30 seconds. I believe it still can do coarse grind if you stop it sooner (510 seconds). No more visits to a grocery store to grind bags of beans in advance!

The liquid nitrogen circulates through the system and is continually replenished from an Autofill system in the exact amount which is required to keep the temperature at 196 °C. Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe.
A powder is a state with microscopic grains, a fluid has subnanoscopic grains. A powder is a granular material, it therefore presents a jamming transition, where the size of grains induces nonlinear flowing of the material. This jamming transition can be seen as an effect of the rather small number of particles in such experiments.
