Rocker Arms: The function of the rocker arm device of the cement vertical roller mill is to transmit the pressure provided by the hydraulic cylinder to the grinding roller, so that it can be transformed into the grinding force act on the material bed. The rocker arm device is mainly composed of upper rocker arm, lower rocker arm, rocker arm shaft, bearing and bearing housing and other components.
