Gyratory Crusher an overview ScienceDirect Topics

The gyratory crushers crush to reduce the size by a maximum of about onetenth its size Usually, metallurgical operations require greater size reduction; hence, the products from the primary crushers are conveyed to secondary or cone crushers where further reduction in size takes place Here, the maximum reduction ratio is about 8:1Jan 12, 2016 As an example, suppose that it is required to make a reduction of 7:1 in two stages of crushers, one a standard gyratory and the other a finereduction crusher We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volumereductionratio in the standard gyratory is considerably higher Crusher Reduction Ratio Mineral Processing MetallurgyFeb 17, 2016 Gyratory Crushers The primary rock breaker most commonly used in large plants is the gyratory crusher, of which a typical section is shown in Fig 5 It consists essentially of a gyrating crushing head (521) working inside a Gyratory Crushers Mineral Processing Metallurgy
