Influence of the milling parameters on the mechanical work intensity in planetary mills F J Gotor 1 of theoretical models proposed in the literature for the energy transfer in milling devices and Mechanochemistry is generally performed in high energy ball mills using powder reactant mixtur During milling the intimate mixing of operator is strongly asked to consider the respective data also Since most ball mills are originally designed to perform particle refinement some suggestions might not agree with the standard literature referring to this topic Type of reaction • The chemistry in ball mills is not restricted to a special type of chemical synthesis if

Aug 15 32 ball mill rpm posted in Newbie Questions ok so I know this is a question I should be able to figure out on my own I thought I know of some web sites that had the equation but I must have been wrong any way the jar is 775 inchs wide and 105 inchs long and I m using 50 cal round musket balls for media it will be half full of media so what rpm should I run it at Thanks so muchMill Speed Critical Speed Mill Speed No matter how large or small a mill ball mill ceramic lined mill pebble mill jar mill or laboratory jar rolling mill its rotational speed is important to proper and efficient mill operation Too low a speed and little energy is imparted on the product
