During choke feeding the crushing action takes place between the jaw plates and particles, as well as by inter-particle compression. Choke feeding necessarily produces more fines and requires careful feed control. For mineral liberation, choked feeding is desirable.
Jaw crushers: Jaw crushers are blunt and often used in the primary crushing stage. They can break up large and hard materials but usually need a secondary crusher to make the rock finer. Gyratory crushers: Gyratory crushers have a conical head and a concave surface. They break through the material using compression methods …
Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. ... reliable operation of the crusher. Choke feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle …
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the …
For industrial jaw crushers, the choke feeding intensity is not considered a critical phenomenon in initial rock breakage. ... The study clearly shows that the …

Developed to crush the hardest ores and rocks, jaw crushers also perform outstandingly with less demanding materials.
This paper will present how choke feeding the gyratory crusher has been found to be one of the main influences on crusher product particle size and plant throughput. It will explain how the effect of choke feeding the gyratory was measured and from that, the various changes made to improve choke feeding of the gyratory crusher.
Choke-feeding a jaw crusher promotes stone-on-stone crushing, breaking up flaky or slabby particles. Photo courtesy of McLanahan corp. and posted in . About …
A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed, where the flow of material to the crusher is throttled in some manner so that the crusher is never completely filled. Aa particle …

Feeding Your Jaw Crusher. Jaw crushers are often choke-fed to maximize production speed. Choke feeding results in stone-on-stone crushing, which can help break apart more flaky materials. However, choke feeding also often results in a finer output. Trickle-feeding will result in larger products but also reduce capacity and jaw crusher efficiency.
A cone crusher that is under fed causes the cone to be overloaded, causing concentrated wear of the bowl and mantle liners. Overloading of the crusher by incorrect feed material can also cause damage to the crusher's internal bushing. What are the benefits of choke feeding a cone?

As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41], the production of fines can be diminished by regulating the mf in the crushing chamber.
