Exploring Jaw Crusher Efficiency | Kemper Equipment
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. Trickle-feeding will result in larger products but also reduce capacity and jaw crusher efficiency.
