Read MoreThe Time that the ore spends in the grinding mill is called RETENTION TIME. This is a very important variable the longer the retention time the more the ore comes in contact with the rods the better and finer the grind becomes. To understand this important control it must be remembered that any volume that is added to a circuit must leave the circuit at exactly the same rate. All the .
Read MoreThe Outokumpu reference gives the base mill charge density for these formulae as 310 lbft 3. . The effective grinding length of a ball mill is the belly length of the mill inside the mill liners from the inside of the head end liner to the inside of the discharge end liner or grate.

Read MoreSTEEL. Steel Shot There are many sources for steel shot but all are not equal since much of the steel shot is used for shot peening. Make sure that the shot is designed as a grinding media or it could tear up the mill. Steel shot is one of the least expensive grinding medias with the benefit of high density and the availability of a wide range of sizes for small media.
Read MoreThe reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250 circulating load and having 38 of fine material reporting to cyclone underflow resulting in a classification efficiency of 50. . The classification efficiency is reduced when operating at higher feed density but lower feed density .

Read MoreUsually plant operators use mill power readings as an indicator of ball filling degree and often try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
