Abstract
An apparatus and method for reliably generating simulations of actual dust suspension conditions and measuring the associated density of suspended dust. The dust monitor is constructed to permit generation of dust suspensions by achieving various pre-selected motions for the test material, such as a rolling motion or swirling motion relative to the forward direction of travel of the test material. The apparatus and method permit prediction and control of the propensity to form dust suspensions during actual operating situations in the field.
