  • CiteSeerX — ECT Studies of Bead Fluidization in Vertical Mills

    CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): ABSTRACT – Vertical media mills require sufficient fluidization of the grinding media in order to be efficient. Fluidization is determined by the agitator speed and, in the case of recirculating mills, also by the flow rate through the recirculation pump. Inadequate fluidization lowers the efficiency of the mill ...

  • Fluidization - Wikipedia

    Fluidization (or fluidisation) is a process similar to liquefaction whereby a granular material is converted from a static solid-like state to a dynamic fluid-like state. This process occurs when a fluid (liquid or gas) is passed up through the granular material.
