GSI's ball mills are housed with oversized roller bearings and a complete drive system discharging mesh sizes from ~40M to <200M. The capacity, or throughput, of our GSI ball mills are directly linked to the particle size of the ball mill discharge. For instance, it is roughly 3 times as fast to reach a 65 mesh grind than a 200 mesh grind.

40 mesh screen (about mm) while most of the product of a fine grinder will pass 200 mesh screen ( mm). Ultrafine grinders will accept a feed of a few mm in size and reduce it to a product of sizes in the range 1 50 m. Cutters will deliver particles of definite shape and size, typically a few mm in length.
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum a...
This point is usually somewhere between 450 and 700 mesh depending on the diameter of the wire or filament used. Note: Beyond 325 to 400 mesh, particle size is normally described only in microns. *Values are based on the American National Standard for Industrial Wire Cloth (American Standard ASTM E 11). Some micron size comparisons

Mesh (scale) Mesh is a measurement of particle size often used in determining the particlesize 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.
Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
A typical ball mill has an L/D ratio of :1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground). Some are compartmented. M Linings may be made of steel, ceramic, cast basalt, silica or rubber. Ball sizes range is size from 6" diameter,
