Roll Crushers. A. Gupta, D.S. Yan, in Mineral Processing Design and Operation, 2006 6.1.3 Roll Crusher Circuit Design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, like chalcocite and chalcopyrite they have been used as secondary crushers. Choke feeding is not advisable as it tends to produce particles of irregular size.

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. ... Choke feeding is important for ™b to maintain approximately 10–15% of material finer than the closed-side setting in the feed to assist ...

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 recommended level ...

In-line Feeding Jaw Crushers should be fed in alignment with a feeder or scalping screen. The discharge end of the feeding machine should align with the crusher's feed opening (or gape). This alignment helps prevent clogging and ensures smoother operation. Choke Feeding For best results, the crushing chamber should be kept at least 80% full.

Because 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.

Secondary crushers are often viewed in the industry as quick intermediate step to prepare feed for tertiary crushers. Key requirements from a top performing cone crusher are aggressive crushing action, high crushing force and high power. ... Often this power flexibility is needed for hard competent rock or for achieving a choke fed crushing ...
