DetailsCHOKE FEED THE CRUSHER {{image2-a:r-w:250}}It's important to choke feed your crusher – in other words, always keep it full of material. By choke feeding your cone crusher, your equipment will run smoother and provide more even liner wear, better product quality (shaping) and the most efficient use of power.
DetailsBecause of that reason, the choke feeding intensity undertakes the role of crushing efficiency. Since there is no standard approach for the evaluation of choke feeding intensity for industrial jaw crushers (Fig. 1), it is required to figure out the mechanism of choke feeding as a function of feeding size and quantity.

DetailsThis 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.
DetailsFeeding 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.
DetailsTypes of Jaw Crushers. Jaw crushers have been around for nearly 200 years at this point and are one of the most "historic" crusher types. Because of this, jaw crushers have advanced technologically through the years to make them more durable and to improve their movement to reduce choking and increase operational speed.
