relationship of crusher capacity to eccentricity and speed for a 42-65 gyratory primary with 6-inch open side setting. capacity is in tons per hour of 100 lb per cubic foot crushed material. eccentric assembly for a 48-74 gyratory crusher, showing spiral bevel gear, cast steel eccentric and bronze eccentric sleeve.
high-speed gyratory crushing > fine cone crushers. the eccentric is direct-driven by a vertical motor mounted above the spider, the drive shaft running down through the hollow-bored mainshaft. speeds range from 480 to 580 rpm, depending upon the size of the crusher, and upon the frequency of the electric current.
the gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m for the largest equipment . this crusher can handle products with a mohs hardness that is not necessarily less than 5.
metso's superior mkiii 60-89 primary gyratory crusher fits a wide range of feed opening ranges, and provides great benefits no matter the need. excellent performance. thanks to upgraded components, the superior mkiii 60-89 primary gyratory crusher has increased speed and more crushing power.

gyratory crushers are operated in open circuit. the feed is limited to 1 to 1.5 meters in size. thus, based on reduction ratio, the rock size is reduced to 10 to 15 cm.
high-speed crushers so far, all of the crushers we have been discussing have been of the low-speedclass; that is, with eccentric speeds ranging between the approximate limits of 100-200 rpm. it is customary, as before mentioned, to rate such crushers at their open-side discharge settings, because there is a definite relationship between these values.
gyratory crushers are principally used in surface-crushing plants. the gyratory crusher (figure 6.5) consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric sleeve. the spindle is suspended from a “spider” and, as it rotates, normally between 85 and 150 rpm, it sweeps out a

the material passing through the crusher is subjected to a series of hammer-like blows rather than being gradually compressed as by the slowly moving head of the gyratory crusher. the high-speed action allows particles to flow freely through the crusher, and the wide travel of the head creates a large opening between it and the bowl when in the fully open position.
these gyratory crushers have been operating successfully in some of the world's harshest conditions for 50 years. this long operating life can be attributed to the robust design that flsmidth still utilizes to this day.
gyratory crushers feature a higher crushing ratio and less tendency to become clogged in the feed zone as a result of bridging jaw gyratory crusher weights 1) type feed opening mantle diameter (oversized) speed of eccentric bushing max. motor power total weight of crusher spider 2) heaviest weight bottom shell 3) main shaft 4) eccentric bushing
any of you that are at all familiar with the gyratory crushers and cone crushers that the former are used as primary crushers will probably note many similarities between the types. each use a cone shaped crushing surface, and the same principal in the eccentric
thanks to upgraded components, the superior mkiii 60-89 primary gyratory crusher has increased speed and more crushing power. the overall performance is also higher since refined design reduce downtime, increase capacity and operational safety.
our experience with mining industries minerals, cement, and aggregate has resulted in a complete line of gyratory crushers to satisfy the requirements of a wide variety of our customers' applications. flsmidth holds a leading position in crushing technology with
