Under normal circumstances, a grinding millwith spiral classifier, hydro cyclone, linear vibrating screen and otherequipment constitute closed-circuit grinding, that is, ball mill rowing throughthe linear shaker grading, the material under the sieve into the nextoperation, the screen materials once again returned to the mill and thengrinding. From the point of view of classification efficiency, the classificationefficiency of cyclone and linear vibrating screen is superior to that of spiralclassifier, and the high classification efficiency means that the amount ofmaterial returning to the ball mill (sand return) in the ball mill is reduced,so that the specification of the ball mill (Barrel volume), the new ore intothe ball mill can increase the amount of ore, a relatively increase theprocessing capacity of the ball mill to reduce unit ore grinding powerconsumption, help to reduce production costs.
In addition, if the slurry into the ballmill before the increase of screening links, the purpose is also ahead of thefineness of the material will be separated out to reduce the amount of ore intothe ball mill (which already contains part of the level of qualified particlesize), while reducing over-grinding ore, so both played the purpose of savingenergy and avoid the over-grinding ore may result in the subsequent sortingprocess.
Tailings (beneficiation designer):
Routine crushing shaker is a three-sectionclosed-circuit inspection and control of screening, with the ball mill is nonecessary relationship, just to control the size of crushed products. Semi-selfgrinding ball mill before the linear vibration sieve, is to sieve stones.
According to more broken less grindingtechnology, in order to save costs, reduce the pressure of the ball mill, to beinstalled vibrating screen before the ball mill.
