Gold Crushing - JXSC Machine

Sep 29, 2019 · Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine. In the early years, common used plate feeder, but now, the vibrating feeder is more popular. Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate and easy maintenance, which can fully meet the needs of both of large scale gold plant ore small scale processing plant.
