Closed or open circuit grinding systems in recent days the ball mill grinding systems are used with the roller press and it is developing very fastly the primary grinding is done by the roller press and finish grinding takes place in ball mill because of this we can increase the ball mill capacity as well as the cement
Dec 03 analysis of particle size distribution for open and closedcircuit ball mills feed and product showed that d 90 value of feed and product of opencircuit mill is and microns
Dec 12 if p is less than 80 passing 70 microns power consumption will be ball mill power calculation example a wet grinding ball mill in closed circuit
However open circuiting the sag mill by feeding crushed pebbles directly to a ballmill circuit is often considered as a technique to increase sag throughput an option to do both can allow balancing the primary and secondary milling sections by having the ability to return crushed pebbles to sag feed as per a conventional flowsheet or to the
If a ball mill circuit were to be fed 2 distributions each with same p80 but with the open and closed circuit gradients in figure 1 the closed circuit distribution would require more energy to grind to the final p80 how much more energy is required is difficult to determine however for the purposes of this approach it has been
In addition the closedcircuit grinding system has the characteristic of high efficiency high output low cement temperature and good comprehensive benefit generally the output of the closedcircuit ball mill is 15 25 higher than that of the opencircuit ball mill with the same

The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material different from continuous ball mill batch type ball mill grinds powder by times and adopts intermittent operation the batch mill is mainly used for the mixing and grinding of materials with uniform product fineness and saving
The comminution circuit is based around a hpgr the circuit was commissioned in september and comprises two stages of crushing closed with a dry screen followed by an hpgr closed with a wet screen and the screen undersize reports to a reverse closedcircuit ball mill online chat mining closed circuit ball mill
The hpgrball mill circuit comprises a reverseclosed secondary crushing circuit prior to a closed hpgr circuit followed by a reversedclosed ballmill circuit with cyclones see figure 2 the vibrating screen decks were set to an aperture size of 32 and 4 mm for the secondary crushing stage and hpgr screen circuit
The main advantages of closed circuitgrinding is highefficiency crushing rate and the production quality is higher in the same period closedcircuit has larger production rate however the disadvantage is that the production flow of closedcircuit is more complex and costs more than opencircuit
Therefore the rod mill has the ability to control the particle size and can be used as an opencircuit grinding equipment although the ball mill does not have the ability to control the particle size itself it can control the particle size with the help of the classifying equipment the mill will discharge ore into the classifying
