Jaw Crusher

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.

Tips for maintaining efficiency in crushing circuits

Uniform distribution of feed material around the cone crusher inlet is a good practice. This allows production of a consistent product, as well as efficient, reliable operation of the crusher. Choke-feeding is important for cone crushers because it maintains a good particle shape by facilitating an inter-particle crushing action.

Understanding the Different Types of Crushers | Agg-Net

Feeding for efficiency. Jaw crushers are routinely choke fed to maximize production capacity and ensure that particles are uniformly broken. This promotes stone-on-stone crushing, which breaks up flaky or slabbier particles. Those seeking fewer fines should try trickle feeding material into the jaw crusher.

Understanding the Reduction Ratio in Crushers

For instance, a jaw crusher with a choke-fed chamber performs best and maximizes production capacity while producing uniformly broken particles. As such, a choke-fed chamber increases your crusher capacity and …

Optimal feed arrangement

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.

The pros and cons of cone crusher applications

Keep the crusher choke-fed. Choke feed means to keep the head covered with at least 150mm of feed material. Conditions that help keep the crusher choked include surge bins, bin level sensors, adjustable speed feeders, and automation. ...

How to Prevent Crusher Choking

We all understand how choke feeding a crusher makes for good operation and product size but operators need to also know How to Prevent and avoid that same Crusher from Choking.

McLanahan | CMB Cone Crushers

To maintain the maximum levels of capacity, gradation and cubical product, a CMB Cone Crusher must be choke fed at all times. The best way to keep a choke feed to the CMB 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.
