Grinding coal into 60 mesh particles also ensured that the CO 2 adsorption data could reflect the real micropore porosity information. The analysis time was significantly reduced in most TDC samples (except for mylonitized coal), in which the original coal has been broken to a certain degree and the adsorption equilibrium can be achieved by ...
Understanding 'Mesh': Converting to Microns Easily
For example, particles sized -100 to +200 mesh can pass through a 100 mesh sieve but not a 200 mesh sieve. When sieving such particles, the sieve with the larger mesh number (200) should be placed below the one with the smaller mesh number (100), and the particles retained in the larger mesh sieve (200) will be those between -100 and +200 mesh.

Basic Ball Mill Grinding Circuit
In some plants a ball-mill or rod-mill will reduce the ore to, say, 100 mesh and a tube-mill will finish the grinding to 200 mesh or finer. In other plants a ball- mill or a tube-mill will do all the grinding, but it must be fed with fine ore—say, 1/8 to ¼ inch—to do this properly. Grinding coarse ore in a ball-mill is done by steel balls ...
