 — A mesh size of 200 means that one linear inch of screen contains 200 openings. So, to know the mesh number, you just need to count the number of openings in one linear inch of the mesh. The larger the mesh number, the smaller the size of the openings and, thus, the size of the particles captured by the mesh.

The capacity, or throughput, of a ball mill is directly linked to particle size of the ball mill discharge. For example, it takes approximately 3 times as long to achieve 200 mesh grind as it does to achieve 65 mesh grind. …

In processing our local ore with the MBMM jaw crusher, hammer mill and shaker table, we get a p80 of ~30-50 mesh (80% passing 30 or 50 mesh sieve screen), depending upon the slot size in the hammer mill screen. Results show nearly 50% of the gold recovered was at <100 mesh, and a surprising amount of gold was at <325 mesh.
