Wet jet milling of Al2O3 slurries

A wet-rotating disc milling was used as a method to prepare ceramic slurry. The rheological measurements of the milled slurries showed that the apparent viscosity of the wet-rotating disc milled slurry was low and the slurry was nearly Newtonian behavior, whereas that of ball-milled slurry was more viscous and the slurry exhibited a very …

Effect of Water & Density on Grinding Mill

This ratio is termed the DENSITY of the circuit. One method of measurement is simply to weigh the slurry to determine the amount of solids in relationship to the water. The density of the slurry is expressed as percentages. As an example, a density of thirty percent means there is thirty parts ore to seventy parts water.
