1. The rotating speed of the movable cone of the gyratory crusher is low the stroke is small. And the ore is mainly crushed and broken and bent. The cone crusher has 2.5 times higher rotating speed and 4 times larger swinging angle than the gyratory crusher so the ore is impacted quickly.
The gyratory body of cone crusher is higher twice or three times of jaw crusher and the workshop cost is larger. The weight of cone crusher is larger than that of jaw crusher with the same output by 1-2 times so the equipment cost is higher. The installation and maintenance of cone crusher is more complicated than jaw crusher.
Mar 20 2018 The input to the cone crusher is much smaller and fragmented than that in the jaw crusher. The granularity of the materials that are crushed in the cone crushers is about 35mm to 350 mm. A cone crusher is best suitable for crushing of materials with high hardness like granite marble pebbles dolomite rhyolite and diabase. Advantages
The cone crusher is a modified gyratory crusher. The essential difference is that the shorter spindle of the cone crusher is not suspended as in the gyratory but is supported in a curved universal bearing below the gyratory head or cone Figure 8.2. Power is transmitted from the source to the countershaft to a V-belt or direct drive.
Oct 29 2019 When energy is introduced to rock ore or mineral crystals will generate a dust emission. The coarse jaw crusher has a large amount of dust emission while the cone crusher is much better. Compared with the cone crusher the sealing of the jaw crusher is relatively poor. The cone crusher spreads less dust with a deep crushing cavity.

Cone crushers and gyratory crushers are mainly used as secondary crushers in a crushing plant. Crushed product from the primary crusher usually Jaw Crusher is fed through the top of the cone crusher and flows over the mantle. A vertical drive shaft rotates the mantle eccentrically below the bowl liner squeezing the product and crushing it between the mantle and liner.
Jul 18 2015 The gyrator crusher consists of a truncated conical casing inside which a crushing head rotates eccentrically. The crushing head is shaped as an inverted cone and the material being crushed is trapped between the outer fixed and the inner gyrating cones and it is again forced into a narrower and narrower space during which time it is crushed.
The cone crusher Fig. 13.12 is very similar to the gyratory type except that it has a much shorter spindle with a larger-diameter crushing surface relative to its vertical dimension. The spindle is not suspended as in the gyratory crusher. The eccentric motion of the inner crushing cone is similar to that of the gyratory crusher.
Jul 25 2015 The greater angle of the cone crusher puts the pivot point below the distributor plate. While the pivot point for the gyratory crusher is at the spider cap. This difference in the pattern of gyration has a purpose. The primary crusher produces a product that is gauged by the size of the open side of the mantle. This is because the slow speed of the gyration allows a high percentage of
