However, in proper mining terms, the size of the holes is expressed in mesh sizes. In simple terms, mesh size is the number of openings per linear inch. If the mesh is 2, it means that every square inch contains 2 * 2 holes, which is 4. Here is a table showing three classifier sizes expressed in inches, mesh size, and openings per square inch

The largest filter is 20 mesh (1000 micron), the middle filter is 40 mesh (400 micron), and the smallest filter is 60 mesh (234 micron). Each of the classifiers have two heavy duty grab handles on them as well.

Aug 17, 2013 Mesh size refers to the number of holes in an inch. The gold cube for instance requires the use of a screen with 8 holes per inch, a #8 classifier. Anything that goes through the screen is -8 and anything that is larger than the screen is +8. I use 1/2 or #2 classifier for my drywasher and then wash the larger material, +2, with a #8 to

openings in one linear inch of screen. This count is the mesh number. A 4-mesh screen means there are four little square openings across one inch of screen. A 100-mesh screen has 100 openings per inch, and so on. As the number indicating the mesh size increases, the size of the openings and thus the size of particles captured by the screen decreases

Classifiers come in a variety of mesh sizes. The mesh refers to the screen size. For example, a 1/2 inch mesh is about 4 holes per square inch; a 1/4 inch mesh has about 16 holes per square inch; 1/8 inch contains about 64 holes per square inch and so on. 1/100 inch is the smallest mesh that is commonly used for microscopic gold recovery and ultra fine gold dust and flakes

Classifiers (mesh screens or sieves) Used to classify (or sort) rocks by size. Gold separation works best when the gravel to be worked consists of similar size particles. This allows the material with a higher specific gravity (such as gold) to settle to the bottom without interference from larger, heavier rocks
