It is necessary that the feed to jaw crushers be carefully designed to balance with the throughput rate of the crusher. When the feed rate is regulated to keep the receiving hopper of the crusher full at all times so that the volume rate of rock entering any point in the crusher is greater than the rate of rock leaving, it is referred to as choke feeding.

· I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged. Both of these

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.

· If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces <a title="Effect of Feed Rock

· As an indirect jaw crushing parameter, the choke feeding intensity was also emphasized by Beloglazov and Ikonnikov [40]. As the rock comminution and energy efficiency can be defined as a function of area increment of particles in jaw crusher [41] , the production of fines can be diminished by regulating the m f in the crushing chamber.

· Choke feeding a jaw crusher maintains a crushing chamber that is at least 80% full.
