Feeding for efficiency. Jaw crushers are routinely choke-fed, as this maximises production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, which breaks up flaky or slabbier particles. If you are seeking fewer fines, trickle-feeding material into the jaw crusher could achieve this; however, this would ...

The feed for Gyradisc crushers usually has a topsize not larger than 75MM (3 In.) for the larger units and 30MM (1¼ In.) for the smaller size crushers. Gyradisc crushers differ from conventional cone-type crushers because the comminution of material is achieved by a reduction process called Inter-Particle Comminution.
