This promotes stone-on-stone crushing, which breaks up flaky or slabbier particles. Those seeking fewer fines should try trickle feeding material into the jaw crusher. Keep in mind, however, that this will have an adverse effect on particle shape and will also reduce throughput capacity, hindering the crusher’s efficiency.
