metso c series jaw crusher manual. 2. 2 metso minerals, the world’s leading rock and mineral processing group,has installed over 10 000 jaw crushers since the 1920s. today the nordberg c series is indisputably the world's favourite jaw crusher. where cost-efficient primary reduction of hard, abrasive materials is concerned, c series crushers
jaw crusher working principle. jaw crusher for crushing materials work, is the material between the two pieces of jaw plate crushing. motor drive transmission mechanism driven jaw plate hanging around the shaft relative to the fixed jaw do periodic reciprocating motion, sometimes close, sometimes leaving in the process of moving jaw plate close
a) primary crusher – the raw material from mines is processed first in primary crushers. the input of these crushers is relatively wider and the output products are coarser in size. example - jaw crusher, gyratory crusher, impact crushers, etc. b) secondary crusher- the crushed rocks from primary crusher are sent to these secondary
above figure shows sectional view of a typical gyratory crusher. essentially, a gyratory crusher consists of a heavy cast-iron, or steel, shell/frame which includes in its lower part an actuating mechanism (eccentric and driving gears), and in its upper part a cone shaped crushing chamber, lined with wear resisting plates (concaves).
be accepted into the crusher is approximately 80% of the gape. 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
the gyratory crusher is made up of six main components , base, main frame and concave liners, drive assembly, mantle, spider arm assembly, oil system. the base is the section of the crusher that provides an entry point for the drive assembly and oil system. it also provides support for the working surface of the main frame and liners.
the gyratory crusher shown in figure 2.6 employs a crushing head, in the form of a truncated cone, mounted on a shaft, the upper end of which is held in a flexible bearing, whilst the lower end is driven eccentrically so as to describe a circle. the crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of the machine are
when you want a crusher that can withstand the harshest requirements, the gyratory crusher (ts) has you covered. the gyratory crusher ts is a high quality, modern design, durable gyratory crusher that was engineered from the ground up with an unwavering focus on performance, safety, maintenance and functionality, for the utmost reliability and efficiency in your projects.
using today’s most modern analysis techniques, flsmidth’s ts gyratory crushers are structurally sound from the inside out. with the top service design, flsmidth not only concentrated on providing a crusher that was durable, but also flexible enough to meet the various requirements of our customers.
crushers • squeeze or press the material until it breaks • mostly used to break large pieces of solid materials into small lumps • use of crushers in agricultural operations is limited . types – jaw crushers – gyratory crushers . jaw crusher • feed is admitted between two jaws, which are open at the top like v

a gyratory crusher may be looked up on as a jaw crusher with circular jaws, between which material is being crushed at some point all the time. a conical crushing head gyrates inside a funnel shaped casing open at the top. a crushing head is pivoted at the top. an eccentric drives the bottom end of the shaft.
with regards to any future expansion in mind, the jaw crusher option is limited in terms of additional throughput capacity. the sag mill may be fed with rationed proportions of coarse and fine ore (±100mm). it was however possible to obtain a close approximation to the supplied size distribution by gyratory crushing at a 5” crusher setting.
of gyratory crusher bucket-type attached to the excavator arm in fig. 9 is presented the 2d section  of the gyratory crusher bucket-type (bucket, item 14) for medium and middle sized crushing with the shaft rested on top. the shaft (item 5), on which is mounted the mobile cone (item 6), protected by armor
the mill however, we have another from a tour of the underground maintenance shop to an up-close look at the gyratory crusher, superintendent, participants took a driving tour to examine various surface locations and facilities across the site. beginning at the historic afton pit,
the crushing action is created by the closing the gap between the hard crushing surface attached to the spindle and the concave liners (fixed) mounted on the main frame of the crusher. the gap is opened and closed by an eccentric drive on the bottom of the spindle that causes the central vertical spindle to gyrate. jaw crusher gyratory crusher
when electric motor of gyratory crusher drives eccentric sleeve to rotate through belt pulley and cone gear, and eccentric sleeve will drive movable cone to rotate around the center line of the crusher, so that movable crusher gets close and then moves away from the fixed cone crusher, so that ores inside the crushing chamber will be squeezed, bent and then crushed.
gyratory crusher operating mechanism. united states patent 2486478. abstract: this invention relates to improvements in gyratory crushers more particularly to improved mechanism for driving the main shaft of a gyrat6ry crusher. crushers of this general type are disclosed in my u. s. patents nos. 1,754,895, 1,985,098 and 2,208,639 for example.
the accident occurred in the gyratory crusher building that contained five floors. the top three floors consisted of the dump floor, the drive floor, and the lube floor. a mill maintenance hatch had been removed on the dump floor eight days prior to the accident. (figure 1, appendix b).
