Grinding Balls Rods As a general figure rod mills will have a void space within the charge of around 20 to 22 for new rods In ball mills the theoretical void space is around 42 to 43 It has been found that as grinding rods wear a 4″ or 4½" rod will generally break up at about 1½" diameter
If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75100 mm 3″4″ rods secondary ball mill with 2540 mm1″1½" balls and possibly tertiary ball mill with 20 mm ¾" balls or cylpebs
Rod Mills A rotating drum causes friction and attrition between steel rods and ore particles Rod mills are less common than ball mills for grinding minerals The rods used in the mill usually a highcarbon steel can vary in both the length and the diameter However the smaller the rods the larger is the total surface area and hence
Usually the grinding system in a modern small concentrator consists of one of the following configurations Open Circuit Rod MillClosed Circuit Ball Mill This configuration has proven in the past to be a most reliable system due to the fact that rod mills are not particularly susceptible to variations in feed size
