1. Introduction. Mineral crushing is the main source of energy consumption in mineral processing. According to statistics, this consumption accounts for about 3550% of the total cost of the mine (Curry et al., 2014), or even may also account for % of the global electrical energy consumption (NapierMunn, 2015).More efficient crushing equipment needs to be developed to reduce ...

As we shall show later, the amount of fines minus 74 μm, produced from this operation, increased compared to the roller crusher circuit. However, the advantage of a lower space requirement, less maintenance, increased capacity and ease of dust suppression were so large that replacement of the entire fine crushing circuit by Duopactor 6900 crushers and screens was found to be ...

An improved approach is presented to model the product particle size distribution resulting from grinding in highpressure roll crusher with the aim to be used in standard highpressure grinding rolls (HPGR). This approach uses different breakage distribution function parameter values for a single particle compression condition and a bed compression condition. Two materials were used for the ...

A number of experiments were conducted on a laboratory batch impact crusher to investigate the effects of particle size and impeller speed on grinding rate and product size distribution. The experiments involved feeding a fixed mass of particles through a funnel into the crusher up to four times, and monitoring the grinding achieved with each pass. The duration of each pass was approximately ...

Roll Crushers. In Mineral Processing Design and Operations (Second Edition), 2016. Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.
