Gyratory crushers. Run of mine material is transferred into a gyratory crusher's upper-level hopper. The walls of the gyratory crusher's hopper are lined with "V-shaped" pieces, the mantle and the concave, like a jaw crusher but shaped like a cone. The ore is discharged through the smaller bottom output hole of the cone.

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.

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. Therefore, it is advantageous to the ore crushing, the crushing efficiency is high. 2. Different applications. In large quarries, gyratory crushers are often used as primary crushers.
A primary gyratory crusher was required to crush iron ore at the rate of 3000 t / h. The largest size of the Run-of-Mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm x 1880 mm with a cone angle of 1 8 ∘.
The gyratory crushers will process raw iron ore material at the site, which is being developed to deliver first ore in mid-2022.
The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. It is possible, when all conditions are favourable, to …

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

Moreover, the crusher feed hopper was modeled to achieve a more realistic representation of the ore falling into the crushing chamber (or crusher cavity) and settling in it. In order to describe the movement of the main shaft, this geometry was firstly tilted at an angle γ = 0.35 relative to its pivot point Q.
The Deep Ore Zone (DOZ) underground mine will be a 25 000 tpd mechanised block cave operation starting production in 2000.

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.
