Mesh is a measurement of particle size often used in determining the particle-size distribution of a granular material. For example, a sample from a truckload of peanuts may be placed atop a mesh with 5 mm openings. When the mesh is shaken, small broken pieces and dust pass through the mesh while whole peanuts are retained on the mesh.
By far the most important physical property of particulate samples is particle size. Measurement of particle size distributions is routinely carried out across a wide range of industries and is often a critical parameter in the manufacture of many products.

weight mill of a similar design to the one used by other workers [14, 15]. The impact was applied by means of a falling mass on a spread layer of (10 X 20 mesh) quartz particles wetted by the desired solution. The size distribution of the broken products was determined, and the percentage change in amount passing a 20 mesh screen calculated.
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
compared to cyanide heap leach methods. A gold mill can be divided into 4 major areas: ore mining and size reduction, leaching, gold recovery, and tailings disposal.
