Jun 08, 2010· A convenient expression for the ratio is the Q value, which is equal to the perce nt wall reduction divided by the percent ID reduction. A Q value of 2 or higher tends to smooth the ID surface. When the schedule does not lend itself to a series of highQvalue draws, it is better to use a highQvalue rod draw followed by a hard sink rather ...

The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the usual reduction ratio is about 8. According to Bond [4], the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as
Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill .
For a given ratioofreduction, the type of crusher with a flared crushing chamber will usually deliver a cleaner product than any of the older types; conversely, more reduction can be performed in the machine without creating excessive fines. The facts outlined in the foregoing paragraph have an important bearing on crushing plant design.
