Our combined experience in ball mill design and process equipment development totals more than 60 years and allows us to put a unique spin on steel and lined mills 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

Recently a mechanistic model of the ball mill has been proposed and the present paper describes its application in the simulation of batch mills operating under a range conditions First-order

Breakage rates of coarse particles in ball mills generally follow non-first-order kinetics and the distribution products from batch milling are often characterized by significant contributions of abrasion besides breakage by impact which are not well described using traditional size mass balance formulations Under such conditions particles are often subject to impacts of insufficient

Stirred ball mills are frequently used for ultrafine- and nanogrinding in food pharmaceutical and chemical industry but only few investigations have been published on empirical or scale-up modeling of stirred ball mills Experiments have been carried out with a laboratory scale stirred ball mill
