When a cubical product shape is required, the following process controls when correctly applied to the crushing circuit will minimize the flat and elongated particles generated inside the cone crusher: 1. Keep the crusher choke-fed. Choke feed means to keep the head covered with at least 150mm of feed material.

• The crusher should be choke fed so that the crushing chamber is full all the time. This is important, especially in fine crush-ing. Choke feeding maximizes the amount of multi-layer crushing, improves the shape of the crushing cavity as it wears and improves the crushing efficiency. => Choke feed level varies.

For performance efficiencies, proper circuitry should be designed around the crusher cone, says Schultz. Importantly, the circuit should be engineered to provide the crusher cone with choke-fed material, or enough material to keep the crusher full. Having too little feed can cause the crusher to side load, which stresses components.

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.

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 moves from level to level it drops a greater distance with each movement of the mantle.

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?

A secondary cone crusher should be matched to a drive motor designed and specified for high load crushing duty. The motor specifications for top performing cone crushers are with a 1.15 Service Factor and a 200% breakdown torque. These specifications enable the crusher to operate for short periods of time at or above name plate motor power.

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.

In order to maintain the maximum levels of capacity, gradation, and cubical product, a Cone Crusher must be choke-fed at all times. The best way to keep a choke-feed to the Cone Crusher is with a surge bin (or hopper) and feeder that are located prior to the crusher. Choke-feeding is almost impossible to achieve without a hopper and feeder.

Cone crusher and gyratory crusher work on the same principle. Both have the same operation. If cone crusher differs then it is only from crushing chamber. Cone crusher has a less steep crushing chamber and more parallel zone between crushing zones. It breaks the rocks by squeezing it between the gyrating spindles.
