Jaw Crusher Speed Rpm

Jaw Crusher Speed Rpm. The speed of jaw crushers varies inversely with the size, and usually lies in the range of 100350 rpmhe main criterion in determining the optimum speed is that particles must be given sufficient time to move down the crusher throat into a new position before being nipped again.
