  • Slurry density effects on ball milling in a laboratory

    Slurry density effects on ball milling in a laboratory

    The effect of slurry density on the dynamics and grinding behavior of a batch ball mill was studied using quartz as a test material. It was found that slurry density determined the distribution of solid charge in the mill, with migration of particles from the tumbling zone to the mill periphery as solid concentration was progressively increased.

    Milling Ball Milling tables

    The working principle of the vibratory grinding mill is based on intense motion of the grinding balls, with both inertia and centrifugal forces. The energy produced using the Sweco mill is higher than that produced by the ball mill, making it more effective in reducing the particles size to 0.5 micron or less.

    The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semi-autogenous mill, as well as the slurry that makes up the operating charge. Let Jt be the fraction of the mill volume that is occupied

    Aug 06, 2015 Ball & Rod Mill Density – How Water Impacts Grinding. Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods.
