Dry Grinding - ALPA Powder Equipment
Dry and wet grinding are two common and effective grinding methods. Usually, in the machine used for dry grinding, the material will contact and hit other particles or rotors in a closed area until it is broken into the required size. Dry milling can make particles reach micron size. But if you want to achieve smaller nanometer sizes, wet ...

Visual Encyclopedia of Chemical Engineering
The heavier the particle, the greater the chance that it exits out the bottom. The cutpoint size, a measure of a cyclone's performance, is defined as the particle size for which half the particles exit at the top and half at the bottom. A coarser (larger) cutpoint means that only larger particles can be separated.

Introduction to Cyclones
particle size. A grinding mill needs a classifier to extract the particles that have been milled sufficiently finely, and to send oversize particles back to the mill for further grinding. A cyclone does this, with the cyclone overflow being the mill final product, and the underflow reporting back to the mill feed. This
