possible to achieve in a cone crusher. The location of the choke level is the criterion which determines the breakage mode. Interparticle breakage is achieved above the choke level while
Jun 03, 2020· Most cone crushers have a feed opening size of 5-14", so material that's larger than the maximum size allowable will need a first stage of crushing before they can be fed into a cone crusher. Final Product Isn't Uniform. Cone crushers do an excellent job of providing finished material that's relatively homogenous.
accomplished within the crusher. Choke Feed Operating the crusher with a completely filled crushing chamber. Choking Stoppage of the flow of material through the crusher, which is usually due to the wet and sticky material clogging exit points. Circulating Load The amount of oversize material returned back to the crusher from a screen in a closed
May 13, 2019· Choke feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action. Trickle feeding is not the best option because it increases the proportion of flaky material in the crusher product, hindering its efficiency.
Jan 01, 2016· Primary crushers are solidly built to receive large lumps of rock directly from the mines and designed for large tonnage throughputs. Basically, gyratory crushers consist of a fixed solid conical shell or bowl (also called concaves) and a solid cone within the bowl called a breaking head (Figure 5.1).The breaking head is fixed to a central spindle, which is hydraulically suspended or ...

Choke feeding. The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance. Choke feeding is about maintaining a constantly high level of evenly distributed material in the feed hopper.
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?
