A Better Understanding of Rotor Dynamics and Support ...

The motor design engineer can predict the bending modes, since they're predied on shaft stiffness and rotor mass. Most machinery has bending modes higher than twice operating speed. There are, however, machines that operate above the first and even the second bending mode (steam and gas turbines, for example).

Tips to maximize crushing efficiency

 · Monitoring the crushing force as registered through the load on the crusher motors, as well as the pressure on the hydraulic mantle adjustment mechanism, will give forewarning of crusher packing problems before they affect your efficiency. Also, the finer the closedside setting, the greater the proportion of fines produced.
