Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
2.1 Energy. Rock drilling, blasting, and comminution (crushing and grinding) consume a vast amount of energy in hard rock mines. As mentioned in Sect. 1, statistics from hard rock mines indicates that drilling and blasting consumes 2% and comminution does 53% of the total energy input in the whole production chain from mining to mineral …

In service since the mid-eighties and used primarily in cement production, high pressure grinding rolls are increasingly being deployed as tertiary and quaternary crushers in mineral comminution circuits, dealing with tougher ores including iron, gold, copper and diamonds. HPGR technology uses inter-particle grinding to reduce particle size and …
's MP cone crushers are the industry standard when it comes to large cone crushing and are known for processing more ore than any competitive unit at the same reduction ratio or product size.
Summary: In today's crushing and grinding circuits in the mining sector the bottleneck is no longer the comminution plant but the classification system. The increasing demands on grinding product fineness make this situation more and more critical. The following article will demonstrate the importance of modern screening technology in the mining sector …
2006), Ray (McGhee et al, 2001) and Kidston (MacNevin and Stephenson, 1997).There have been several others since, including Phoenix (Lee et al, 2013) and Copper Mountain (Westendorf et al, 2015).North Parkes (Sulianto et al, 2016) is an excellent example of comminution circuit optimisation following a secondary crusher retrofit, maximising …

The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstrea...
The ore is choke fed into the crushing chamber between the rolls which promotes crushing in the bed of particles. Compared to conventional roll crushers where crushing occurs between and in contact with the two rolls, contact between the rock and the surface of the roll is limited reducing abrasion of the rolls. HPGR technology has also …
