cone crusher. cone crushers are similar to gyratory crushers in that they have a mantle that rotates within a bowl, but the chamber is not as steep. they are compression crushers that generally provide reduction ratios of 6-to-1 to 4-to-1. cone crushers are used in

create more environmental friendly quarry operations. two major issues in quarry operations are: 1. energy wastage due to inefficient flowsheet development of the quarry processing operations 2. generation of fines from crushing (nominally -4 mm) which cannot be utilised and sold. these sometimes have to be stored and stockpiled on site.
quarry manager heidelberger sand und kies gmbh, germany the lokotrack® lt130e™ mobile jaw crushing plant is the right choice for primary crushing in quarry operations. its heavy-duty design guarantees a reliable solution and high capacity, even with the hardest feed materials. the lt130e can operate electrically with an external power source
the nordberg® c130™ jaw crusher on the lokotrack lt130e takes your capacity to a new level in large-scale quarry applications. a deeper 1,000 mm (40”) feed opening is able to handle coarser feed material and greatly reduces the need for blasting. a small nip angle and excellent kinematics ensure aggressive crushing along the whole length

types of crushers crushers are classified according to the stage of crushing which they accomplish, such as: primary,secondary,tertiary a primary crusher receives the stone directly from a quarry after blasting, and produces the first reduction in size. the output of the primary crusher is fed to a secondary crusher, which further reduces the
as with other compression crushers, the cone crusher yields a somewhat elongated and slivery particle shape. this may be minimized, however, by 'choke' feeding the crusher. this technique will also make the shape and size more uniform. one way to choke feed is with a surge hopper and a controlled belt-feed to the cone crusher (figure 5-10).

crushing 2. gyratory crushers the original patent for the gyratory crusher was granted to phile- tus w. gates in 1881. this fint crusher was used by the buffalo cement co. at the time these early gyratory crushers were developed all mining and quarrying, either underground or open pit, was done
the chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement of the mantle and the cone at the discharge end in the cone crusher. this is illustrated in figure 5.2. reduction ratios in the following ranges are common for cone crushers: 6:1 - 8:1 for secondaries 4:1 - 6:1 for tertiary and quaternary crushing.
this is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing.
