Verification of Pilger Mill Performance
24-09-2018· The conversion of the rolling mill to a pilger mill consisted of removing the mechanical linkages that connected the gear motors to the roll dies. The pilger mill system was designed to use index- able servo motors that are connected to the large drive rolls directly. This design allows for more flexibility in the degree and speed of die rotation.
