The circuit comprises a sag mill, 12 m diameter by 6.1 m length belly inside liners, the effective grinding volume, two pebble crushers, and two ball mills in parallel closed with cyclones. the sag mill is fitted with a 20 mw gearless drive motor with bidirectional rotational capacity.
Load in a closed grinding circuit. his original graph of the relationship figure 1 has been reproduced with various modifications in many publications. according to this wellknown relationship, the grinding capacity of a given mill is doubled by including a closed circuit classifier producing a
The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Ball mills are also classified by the nature of the discharge. they may be simple trunnion overflow mills, operated in open or closed circuit, or grate discharge lowlevel discharge mills. the latter type is fitted with discharge grates between the cylindrical mill body and the discharge trunnion.
Cement manufacturingbrief description of a cement mill. cement clinker is usually ground using a ball mill. this is essentially a large rotating drum containing grinding medianormally steel balls. as the drum rotates, the motion of the balls crushes the clinker. grinding systems are either open circuit or closed circuit. in an
