Sweco Vibro-Energy Grinding Mill. The Sweco mill operates with five 5 1L jars and it comes with an adapter to allow a 0.5L jar to be secured in one of the 5 positions. The working principle of the vibratory grinding mill is based on intense motion of the grinding balls with both inertia and centrifugal forces.

particle movement within the grinding system the Markov chain model for the circuit consisting of a tube ball mill and a high efficiency separator was introduced through the matrices of grinding and classification. The grinding matrix was calculated using the selection and breakage functions whereas the classification matrix was defined from the

Therefore to compare all three circuits the target grind size was selected to be a P80 of 75 m. See Table 1 and Figure 4 For grinding to a P80 of 160 m the HPGR-ball mill circuit required 21 less energy than the SABC circuit. The main savings result from the lower energy required by the HPGR as compared to the SAG mill.
A third grinding line was installed during a subsequent expansion with full production achieved in April 2004. The first two identical grinding lines Line 1 and 2 consist of one 32s x 13.5 ft 8000 kW installed power SAG in series with one 22 x 36ft 8000 kW ball mill eachone. The third grinding line Line 3

Figure 2. Ball Mill Grinding Circuit The ball mill is in closed circuit with a sump and three cyclone classifiers. The ore and trim water are added to the ball mill and the outflow from the ball mill goes to a sump where additional water is added. The slurry from the ball mill is pumped out of a sump into two cyclone separators. The underflow .
