The crushing circuit includes a larger gyratory crusher 60quotx113quot hd equipped with 1,000 kw and the addition of a secondary crushing circuit 2x750 kw crushers. in addition, this system is complemented with additional crushing capacity in the pebble crushing circuit 2x750 kw pebble crusher.
The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. jaw crushers are mainly used in plants producing up to approximately 1600 th. primary crushing

The scope of this thesis is to examine the dynamic relations between the sag mill and the pebble crusher in a closed circuit and thus to optimize the circuit efficiency by controlling the pebble crusher operational settings. in this thesis, two modeling techniques are proposed for simulating the dynamics in the grinding process.
Between the sag mill and the pebble crusher in a closed circuit and thus to optimize the circuit efficiency by controlling the pebble crusher operational settings. in this thesis, two modeling techniques are proposed for simulating the dynamics in the grinding process. the first method is the fundamental modeling method, where the underlying
The pebble crusher was reduced in size and the pebble bin capacity was increased to allow for a more consistent flow into the pebble crusher. uncrushed pebbles were returned directly to the sag mill, bypassing the pebble crusher, to further improve circuit efficiency.
Pebble crusher is always used with sag mills in metal ore crushing and processing in a recirculation circuit. usually, cone crusher, impact crusher play the role as pebble crusher in gold ore crushing, copper ore crushing, iron ore crushing and so on.
