Failure Stress Estimation of Table Liner for Vertical Roller Mill

Article Preview

Abstract:

A roller mill is composed of several rollers, rotational table liners, hydraulic cylinders and raw materials are ground between the rollers and the table with the assistance with a shearing and compressive force. It has been reported that an unexpected fatigue failure occurred in a table liner in the course of grinding portland cement. It is subjected to the cyclic bending stress by the rollers load and the centrifugal force by the table rotation and fractures at the edge of grinding path of outer roller. It demands design life 4×107 cycles but has fatigue life 4×106 ~ 8×106 cycles. The purpose of this study is to reveal the failure mechanism of the table liner occurring in the grinding operation of roller mill and to show the structural design guidelines for reducing the fatigue failure.
