• The load-carrying capacity of a column is affected by the end support conditions. - Restraining the ends of a column with a fixed support increases the load-carrying capacity of a column. - Allowing translation as well as rotation (i.e. free end) at one end of a column generally reduces its load-carrying capacity.

In a horizontal media mill, the heated/cooled grinding chamber contains an agitator or milling shaft, round beads, and a low viscosity diluent. The liquid/solid formulation is pumped through the fluidized horizontal media at a controlled rate, and the solid particles are broken down or reduced in size and finely dispersed throughout the liquids.

load is two dimensional and contained in a radial plane whilst under misalignment it is three dimensional. The movement is also periodic with base frequency equal to the rate at which the rolling elements pass through the load zone. Frequency analysis of the movement yields the base frequency and a series of harmonics.
