Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and ...

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.
