The majority of gyratory crushers are used as primaries, i.e. they receive the initial feed from the mine or quarry. The same type of crusher with chamber modifications is used as a secondary crusher, particularly when following a large primary crusher. The fine-reduction gyratory crusher can also be used for tertiary crushing.
Comminution by gyratory crusher is the first stage in the size reduction operation in mineral processing. In the copper industry, these machines are widely utilized, and their reliability has become a relevant aspect. ... 4.0 Upper mantle diameter, φup,mt (m) 1.4 Lower mantle diameter, φlo,mt (m) 3.3 Upper concave diameter, φup,c (m) 4.9 ...

A Gyratory Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory cone crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory cone crushers can be used for primary or secondary crushing. The crushing action is caused by the closing ...
The mantle bottom diameter is 3.3 m, and the height is 4.0 m. The mean side angle of the mantle is 100° relative to the horizontal. The concave bottom diameter is 3.5 m. ... Figure 9 illustrates an example of the prediction of forces on the mantle of the gyratory crusher with the DEM simulation in steady state. Each vector represents the …
The crusher is characterised by an especially enlarged, serrated feed opening. Jaw gyratory crushers can handle much larger chunks of material than comparable gyratory crushers of the same mantle diameter and feature a higher crushing ratio, with less tendency of clogging and bridging.
The mantle oscillates, causing a decrease in the volume between the mantle and concave, resulting in the crushing of materials. In contrast, the working principle of gyratory crushers is based on the gyrating motion of the main shaft, which causes the crushing head to move down and crush the rock fed into the crushing chamber.
