     · Also determined at this time is the need for welding or grinding of worn outside faces. In some cases the area where the shaft spacer rides up against the roll face can become worn (known as face wear) because of misalignment in the tube or pipe mill. The misalignment causes an indent to form on the outside face around the bore.

  • Effect of agitator shaft direction on grinding performance

    In this study we investigated the influence that the direction of the agitator shaft has on grinding performance in a media stirring mill. First we proved by milling experiments that the media stirring mill with the horizontal direction of the agitator shaft can provide better grinding performances.
