Impact Crusher an overview ScienceDirect Topics

Impact crushers (e.g., hammer mills and impact mills) employ sharp blows applied at high speed to free-falling rocks where comminution is by impact rather than compression. The moving parts are “beaters,” which transfer some of their kinetic energy to the ore particles upon contact.

Impact crushers high-quality impactors TON Outotec

Impact crushers are named after the method they use in reducing larger blocks of rocks to smaller grain sizes. As the name suggests, an impact crusher accelerates the feed material to high speed and then flings the fast-moving rocks against the walls of the crushing chamber and each other.

Jan 04, 2019 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 have an adverse effect
