Ball Mills
Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...

A bond ball mill work index may also be used in the simulation and optimisation of existing mills and the associated grinding circuits sample requirements a minimum of 8 kg of material crushed to nominally minus 10 mm is preferred jktech would stage crush the sample to minus 335 mm as required for the bond ball mill work index test feed.
Ball Mill
Ore production line using ball mill is prove to be low energy consumption and highly efficient. There are two step in this process, first ores sent to the primary crushing (jaw crusher) to get the enough fineness then sent to the ball mill for the second crushing transported using elevator with regularly feed.
