It is that point or zone in the chamber where the volume of material can approach a solid mass. • The material can become compact, restricting progress down to the next crushing zone, drastically reducing capacity. This is known as the choke point.

Read More17-02-2016 · Choke-feed implies a completely filled crushing chamber (or as full as the design will permit), with a sufficient head of material above the receiving opening to keep the crusher full continuously. This contrasts with regulated-feed, which implies that the flow of material to the crusher is throttled to a point somewhat below the capacity of the machine, so that the

Read More10-03-2016 · For proper operation, the crusher always operates with a choke level in the cavity. A controlled feed race permitting a constant power draw is required for an efficient circuit. Through proper application of the Gyradisc crusher, mill feeds of
Read Morecrushing cavity (Evertsson, 2000). Crushing liners are subject to wear; regular replacement and wear compensation are required. To provide maximum throughput, reduce wear, and minimize the crusher stresses, a mode of operation wherein the crusher inlet is fully covered with feed material (choke feeding) is recommended (Evertsson, 2000).
Read MoreNon-choke feeding to crushers is avoidable through smart plant-wide crushing plant controls. But in order to estimate severity of that in a systematic manner is not straight-forward without constant monitoring and reporting. The crusher choke feeding report makes use out of crusher cavity level sensors by analyzing their level measurements.
Read MoreCone crushers were originally designed and developed by Symons around 1920 and therefore are often described as Symons cone crushers. As the mechanisms of crushing in these crushers are similar to gyratory crushers their designs are similar, but in this case the spindle is supported at the bottom of the gyrating cone instead of being suspended as in larger gyratory
