The Importance of Choke Feeding a Cone Crusher (Applies to the Cone Crushers UD211, QH331, QH440, US440 and UH440) It is very important to choke feed your cone crusher to ensure even liner wear and thereby extending the life of the liners. This will also ensure that the machine will run smoother and increase your quality of …

Try to choke-feed any compression-type crusher. Remember, we are using gravity and the weight of the material to push or force material through the chamber. Since in a compression machine the material breaks to fill the air pockets or voids in the chamber, a non-choke chamber will produce a slabbier output than a choke-fed chamber. ...

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.

Inasmuch as these volumes pass the choke-point in the same time-period, the gyratory crusher capacity through the 13-14 zone is obviously the greater of the two. These two facts account for the superior performance of the standard gyratory and the standard jaw crusher when fitted with non-choking liners.

A crusher with a high choke-point incorporated in its design is not appreciably affected by choke feed.

At the high feed rate, the crusher was choke fed, ensuring the crusher could run at maximum capacity. The low feed rate allowed the crusher to run empty during the crushing; hence involving a lower density of material in the crusher and reduced throughput. The feed rates were not fixed, but manually adjusted by the crusher operator.
