Capacities and performance characteristics of jaw crushers

Although jaw crushers are extensively used for a variety of materials, their operational characteristics are not well understood. This lack of understanding makes selection of the proper machine difficult. Hersam (1923) proposed a method for calculating capacities using a Dodge-type jaw crusher. The equation proposed by Hersam includes a number of constants that are only qualitatively related ...

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The primary operating variable available on a crusher is the set and on jaw and gyratory the open-side set (OSS) is specified. This reflects the fact that considerable portions of the processed material fall through ...
