Up until now tumbling mills such as AGSAG mills and ball mills have had a dominant bearing on the design and economics of comminution circuits. However it is commonly agreed that the majority of employed comminution processes are energy intensive and energy inefficient accounting for up to

ball ore ratio there are other factors that combine to cause these events. Typical causes in overflow ball mills Insufficient ball charge A high ratio of ore to ball charge in a ball mill significantly increases thelikelihood of a locked charge and should be prevented whenever possible. Incorrect flush out during previous mill shutdown sequence
Coarse Grinding Rod mills are generally used as coarse grinding machines. They are capable of taking feed as large as 50 mm and making a product as fine as 300 microns. ii. Fine Grinding Fine grinding which is the final stage of comminution is performed in ball mills using steel balls as the grinding medium. The ball mill after feeding .

Ball Mill versus Vertical Stirred Mill A vertical mill was drawing 43 less power than a ball mill Small media was 30 more efficient than 25mm balls in VSM The new Vertimill with 25mm media was 60 more efficient than the ball mill
sag mills rod mills and crushers whereas it was less important for fine grinding ball mills. For very large and very long mills different constraints come into play and extending models to these mills will extend our understanding of the process. Crusher models including prediction of power usage are widely used. Models of comminution circuits
HPGRs fit perfectly in comminution regimes across many applications. Tertiary and quaternary crushing stages can be replaced by a single large capacity unit operation also having the ability to take-over part of the ball mill grinding task. Requiring less process stages an HPGR significantly reduces overall circuit energy consumption grinding

Results from this research showed that operating the first-stage HPGR in open circuit and the second stage in closed circuit with a 710 m screen resulted in a circuit energy requirement of 14.85kWht a reduction of 9.2 and 16.7 over the HPGR ball mill and cone crusher ball mill circuits respectively.
on the ball mill was on the high side with an actual operating power draw of 5300 kW meaning it was operating at 90 of its maximum power. The combined power draw of the SAG mill and ball mill was 8658 kW which caused partial over-grinding. From experience in processing plants outside of China
