Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuitIn terms of a specified circuit product size which is used to differentiate between coarse or oversize material and fines or undersize material these basic functions are a breakage of the coarse material and b removal.
Because you want the grinding balls to experience a free-fall motion iCataracting motion i would recommend you consider a rotational speed between 65 and 85 of the critical speed of the mill.
Both mills are driven by 4500 hp motorsIn 2007 several comminution circuit studies were performed to assess circuit performance and map a course for improvementThis paper discusses the results of those studies including an analysis of mine-to-mill opportunities grinding work index efficiency and ball mill functional performance.

Simine gearless mill drives’ rpms can be tailored to your operations at any time and are infinitely variable and uncomplicatedWhether manually or fully automatic – rpms can be adjusted to account for the proper-ties of the ore resulting in significantly less wear to the mill lining.
00 mm sample was further ground by a vibration ball mill qinhuangdao taiji ring nano products cohebei china to obtain ultrafine powderUltrafine grinding was performed by mixing 100 mm wheat straw with zro 2 balls 6–10 mm in diameter in a volume ratio of 1:2 for 8 h with the temperature being maintained below 30 c.
